A Pack For All Occasions: Osprey Kestrel 48 Versatility

Osprey specializes in designing and producing a range of backpacks for specific activities and practical applications. For example, they do packs for long trips, short trips, hiking, sporting, camping, and just for popping down to the shops. Get the drift?

In a nutshell, the Osprey Kestrel 48 is the ideal choice if you are looking looking for small-ish multi-day hiking or camping backpack that is lightweight and yet really durable. It is also a great pack if you want to take your bag as carry-on luggage so is perfect for budget backpackers or weekend breaks.

In the following sections, I will explore the the Osprey Kestrel 48’s key features. I will take an in-depth look at its weight, its organizational options, its breathability, fit/sizing, and of course,  how it compares to against other backpacks in its category.

Let’s get to it…

Osprey Kestrel 48 review

The Osprey Kestrel 48 is the ultimate mid-size backpack.

 

Quick Answer: The Osprey Kestrel 48 is perfect for You if…

  • You are a dude (or at least built like one… there is a Women’s equivalent model available)
  • Your plan is to go on overnight backpacking trips of less than a week.
  • You are only packing the bare the essentials for your trip.
  • A full-featured backpack is more important than a minimalist style..
  • You want to take a backpack as a carry on for your flight.
  • You need a backpack with a rain cover.
  • A backpack with the ability to attach a sleeping pad/tent is important to you.
  • You need a backpack that is adjustable and very comfortable.
  • A kickass lifetime guarantee is important to you!
  • You want to look cool whilst trekking.

The Osprey Kestrel 48 is the brands no-frills solution for backpackers, hikers, campers and festival goers needing a straight-up backpack for short(ish) trips.

As with a lot of the Osprey range, one of the Kestrels best qualities is its weight (or lack thereof). The Osprey Kestrel 48 weighs as little as half as much as other backpacks in its class, making it very attractive to ultralight thru-hiker crowd.

Seriously guys, I recently upgraded to this from a lesser pack and I cannot BELIEVE how light this feels in comparison!

Mercifully though, the Kestrel 48 doesn’t compromise on comfort or flap on fit in the name of saving weight. The Osprey Kestrel was designed with the same quality, ventilation features, and adjustability as Osprey’s full-featured (i.e bigger) hiking backpacks.

If the above-mentioned features are important to you, then the Kestrel 48 may just be the answer to your short to medium duration backpacking prayers!

The Osprey Kestrel is not for every backpacker though, as it does have its limits, which I’ll cover below.

 

Quick Answer: The Osprey Kestrel is NOT the perfect backpack for you if…

  • You are planning a long trip and need heaps of gear. The capacity is only around 48 liter.
  • Your average trip will be a multi-day, winter camping trip where you will need heavy gear.
  • This pack is out of your price range. These packs are not budget buys.
  • You don’t travel light.
  • Urban travel is your style. You don’t plan in doing any trekking. You may be better of with the Nomatic backpack or an alternative, like the Tortuga, instead.
  • You want a travel bag with wheels.  This bag doesn’t have wheels.

Not all Osprey backpacks were created equal. They are all unique and all have their own strengths and weaknesses. If you don’t plan on using the Kestrel to go hiking, camping or maybe to a festival, then there may well be another pack out there far better suited to your travel needs.

However, Kestrel does still work well in an urban environment. The Kestrel 48 is kind of a as “jack-of-all-trades” type backpack so it will work for a multitude of travel occasions.

I personally use mine when I go on city breaks or when I travel to see my girlfriend in Nantes. However, if you want storage space for electronics, folders, and the related work equipment, you may find the Kestrel to be ill-suited. To be honest, sometimes it is a bit of a squeeze to get my laptop into it.

 

Osprey Kestrel 48 Review: Key Features

The Kestrel 48 is a functionalist hiking backpack that offers the essential features where they are really needed and cuts all the excess ones which, let’s face it, are seldomly ever even used.

It’s lighter than 1.63 KG so if you want to keep your base weight (ie, the weight of the backpack when it’s empty) to a minimum whilst still having plenty of carry-comfort power, then the Kestrel 48 was designed for that exact purpose.

This is a major pro for me as I hate the excess weight and like to feel as light as possible when traveling.

So let’s take a look at what the Kestrel 48 has to offer… Check out the video below for a quick visual rundown of the Osprey Kestrel 48.

 

Osprey Kestrel 48 Warranty (The awesome ‘All Mighty Guarantee’)

Osprey’s lifetime warranty (dubbed the All Mighty Guarantee!) is pretty unique in the industry and is definitely one of the best things about the Osprey brand.

The All Mighty Guarantee is basically a lifetime warranty.  No matter when you bought your bag, you can post it to Osprey and they will fix many problems free of charge. Of course, you will have to pay the shipping cost to get it to the repair center but it’s still a lot cheaper than having to buy another pack.

This warranty is great for seasoned travellers and adventurers who drag their packs countless miles, packing and unpacking it innumerable mornings and nights.

Basically, if you spend long enough on the road or on the trails, then eventually your backpack is going to need some kind of repair. You will need this guarantee sooner or later.

Therefore, a lifetime warranty for your backpack is one of the most valuable things you can have. This is a testament to Osprey’s high-quality products, these guys really are prepared to put their money where their mouth is and sell products guaranteed to last a lifetime.

Ospreys Customers Service is also pretty awesome and the repair centres’ communication and turnaround times are very commendable.

However, it is worth noting that the guarantee does not cover accidental damage, environmental damage (ie if you let it get damp), airline damage, and crucially, wear and tear. Whilst the All Mighty Guarantee is a massive bonus, it is not entirely infallible and you should contact the repair center before you send your pack to them to ensure that you are in fact covered.

Osprey Kestrel 48 Size and Fit

The Osprey Kestrel line comes in two sizes: 38 and 48. For clarity sake, we are obviously looking at the Kestrel 48 for the purposes of this review. Again, these are ideal for city breaks, hikes and 3-day camping trips. That said, by packing lightly and cleverly, I managed to live out of mine for over 2 weeks last summer in Hungary and also completed the 11-day Anna Purna circuit in Nepal with a previous (lesser quality) 45-liter pack.

The Kestrel is designed in “one-size-fits-all” sizing format. However, the pack is very highly adjustable and will gladly fit a wide range of torso lengths (large to small, a pack for all!)

For a woman specific size, check out the Kestrel’s sister pack: the Kyte 46. We have a full Kyte 46 review with much more information!

Osprey Kestrel 48 review

Adjustable and agile, the Osprey Kestrel 48 delivers a fit and shape conducive to crushing trail miles.

 

Why the Osprey Kestrel 48 Airspeed Suspension Kicks Ass

As we already know, the tensioned back panel can quickly be adjusted to fit a wide range of torso lengths whilst also providing ventilation to reduce sweating (and if you are not breaking a sweat out on the trail, then you ain’t trying hard enough!)

The LightWire frame shifts the weight of the load onto the hip belt. This takes the weight off the backpacker’s shoulders and provides a balanced, comfortable carrying experience.

Seriously, because of this feature, you can carry double the weight. It is the difference between actually enjoying the hike and feeling like Jesus carrying his cross to Golgotha. Never ever buy a pack without it.

The back panel design truly provides superb ventilation. If you have ever been on a punishing hike, then you know your back will soon be rolling in sweat beads. It will make you stink and can also cause infection and rashes, so this is another essential feature for any serious backpacker.

The Kestrel 48 provides sufficient room for air to freely flow down your back because there are a few inches separating your back and the pack.

When you are hiking, you are going to sweat some and that’s absolutely fine. This is why having a backpack  that actively combats stagnant sweaty pockets can go a hell of long way to cutting down on unnecessary discomfort, water loss and rashes.

Osprey’s recommend load capacity limit is between 15-25KG. If you go beyond this you risk damage to the pack as well as causing yourself difficulties in actually carrying it.

Osprey Kestrel 48 review

Love that airflow…

 

Osprey Kestrel 48 Weight

Quick Answer: 1.63KG

All too often, lightweight, small backpacks simply do not have the same long-lasting durability as backpacks built with heavier material. This is not the case here, the Kestrel 48 is relatively small but strong as hell!

When you go hiking (or do the long walk through an airport), every last ounce or gram matters. Therefore, using a backpack which is light from the start will definitely assist you to keep your trail weight to a bare minimum.

The Osprey Kestrel 48 is a good candidate for an ultralight thru-hiking backpack.

 

Osprey Kestrel 48 Storage and Organizational Features

The Osprey Kestrel 48 is simple and user-friendly. It features a main compartment and a few side pockets. There is also additional features which allow you to pack both a sleeping bag and sleeping pad.

The main compartment is easily accessible with a single side vertical zippered access point. It is also spacious enough to pack most of your gear in there, if you wish to. However, the Osprey backpack allows for the rest of your gear to be neatly organised, thanks to a hipbelt and its lid zipped pockets. This is great for keeping valuable items close at hand.

It is also possible to attach larger items (such as a sleeping pad)  onto the lower external straps. Then, your sleeping bag can be stored in the base compartment with internal zip divider.

The sleeping bag compartment in all of its glory…

As I said, this pack is perfect for multi-day hikes and camping trips.

The top lid of the pack has an integrated storage pocket for keeping quick access items close at hand. The two mesh pockets on each side – though not zippered – provide ample space for a water bottle and other gear storage.

More zippered pockets are found on the two hip belts. I love hip belt pockets as they make it easy to access my phone for photos, stash an energy bar, and safeguard my lip balm.

Love me some hipbelt pockets…

 

Stow on the Go Trekking Pole Features

Oh, and if you like to trek with poles, Osprey developed an awesome “Stow-on-the-Go” system, which means no more ‘pack on pack off’ to store your trekking poles.

Instead, you simply pass the poles through two elasticated loops for a hands-free solution. There is even an ice axe loop that may prove useful in winter conditions or on our organized Pakistan tours!

A front stretch pocket allows you to stow away any wet clothing from the rest of your gear.

One can easily secure a tent or a sleeping pad on the outside of the sleeping bag compartment using the compression straps.

All said, with 48 liters of storage space plus the exterior straps, you should be able to pack everything you need for a weekend camping trip or my forthcoming, one week long summer backpacking jaunt across Spain.

Kestrel 48 review

If trekking poles aren’t your thing, the Osprey Kestrel 48 has plenty of ice axe storage as well.

 

Using the Sternum Straps and Hip Belt Adjustments

For the perfect fit for your body shape, you just need to adjust the sternum strap and hip belt. Depending on exactly where you want the sternum strap to be placed, you can slide the sternum strap up or down the rail it is attached to.

Take care not to knock the sternum strap clip off of its rail – this is pretty hard to do – as it is a real pain to reattach. I actually had to send an old Osprey backpack back to the company as it was impossible to reattach the sternum strap clip to the rail, despite my best efforts.

As I mentioned before, the hip belt features two pockets, one on each side.

Kestrel 48 review

Use the different adjustments to dial in the pack just right to fit your body.

 

Osprey Kestrel 48 Price

How Much is it? $180.00 USD

Osprey products are definitely not cheap. You can find another 48 liter pack for as low as $100 and even other “name” brands enter the market at around $130. However, it really is a great value and is definitely worth the money.

Remember, the old adage, “buy cheap, buy twice,” so unless you want your pack to break apart in the middle of a hike, spend the extra money! Besides that, technical backpacks in this range sometimes costs double the amount. Doesn’t seem expensive now, does it?

The more expensive backpacks in this range are usually pricier because of added features and durability. Remember though, in a 48 liter pack you may not need these features and they will also add weight. As for the extra durability, remember the Osprey All Mighty Guarantee.

Ultimately, as with all things, just because a backpack is more expensive doesn’t mean that it’s better. We feel that Osprey strikes the perfect balance between offering plenty of functionality and durability, and being affordable for the lay-person.

In summary, the golden rule is the best backpack is simply the one that best serves your needs.

One last word on price – $180 is not a massive investment for a backpack. If you want, you can use it for years and years and miles and miles. Oh, and if you ever want sell it, the eBay resale values are not bad.

For those shorter trips, the Kestrel 48 packs in a tremendous value. I am using mine quite a lot these days.

If truth be told, you can’t put a price on Osprey quality or comfort…

 

Does the Osprey Kestrel 48 Come with a Rain Cover?

I’m British. I would never buy a hiking or camping pack that did not have a rain cover. So yes, the Osprey Kestrel 48 comes with a rain cover! (Weirdly, for some years Osprey did not include rain covers with their backpacks, which was damned irritating).

The rain cover on the Kestrel sits in its own storage pocket waiting for those watery occasions – it can quickly and easily be whipped out when the storm clouds roll in, at only a mere moments notice.

The rain cover is also adjustable which makes it very easy to secure it to shape the backpack stopping it from falling or blowing of.

This is another essential feature. Having a rain cover is absolutely crucial for most hiking or travel adventures and you should not set of without one (OK granted, there are some places on earth where it never rains, but not many!).

When the weather takes a turn for the wetter, you absolutely need to keep your things dry, especially your sleeping bag! (I slept in a wet sleeping bag in a cave in Pakistan once. It was not fun)

Having a rain cover is therefore essential. It is equally important that the cover can also be accessed quickly and easily. This pack has you covered here.

Quick tip guys – even though the Osprey Kestrel 48 has a kickass rain cover, you may still wish to consider packing dry bags because they provide that extra bit if protection and help to guarantee that your stuff will stay dry.

Psst! If you’re going on some daring adventure deep into the jungle and need a serious 100% waterproof humidty-proof backpack, then check out my in-depth review of the best waterproof backpacks for adventurers.

(Did I just spend the last 10 paragraphs talking about a rain cover? Man, this morning’s coffee must have been strong!)

Kestrel 48 review

The rain cover storage pocket provides easy access for when the skies open up.

 

Is the Osprey Kestrel 48 Compatible with a Hydration Reservoir?

Yeah, it is. Hiking is thirsty work after all.

However, the Osprey hydration reservoir is not included and is sold separately. If you do buy the hydration reservoir, note that the water is not included. You will have to source this yourself either from the sky, a cactus, or maybe your kitchen sink.

Personally, I do not use “camel packs.” I prefer to drink from a good ol’ water bottle or sometimes, for a treat, drink from a puddle like a dog. However, I know some of you guys love them and so rest easy that the Kestrel 48 offers you the option of attaching one.

The internal hydration reservoir sleeve carefully holds the reservoir into place so there is no danger of it moving around.

Osprey Kestrel 48 vs the Competition

First up, my previous 45 liter backpack was a total piece of shit. I am not going to name and shame but I do want you guys to know, there are some truly awful competitor products out there.

However, the Osprey Kestrel does have several competitors even within the Osprey brand (a bit of sibling rivalry never hurt anybody, said Cain to Abel…).

The Osprey Exos 48 is a similar product and worthy rival. Like the Kestrel 48, it is full framed, but less featured, ultralight, and perfect for those short(ish) trips, multi-day hikes, and camping trips.

Kestrel 48 review

The Osprey Exos 48 is another solid option for backpackers looking for a more minimalist bent…

 

Cons of the Osprey Kestrel 48

No backpack is perfect (although The Broke Backpacker does have plans to one day invent one. Stay tuned).

My main gripe is that the metal frame ventilation system on the back makes the pack a little more sturdy and inflexible then I would like so it can sometimes be a bit challenging to deep pack. It also protrudes that bit too high so it can restrict head movement.

Some of the compression straps are also a bit long and dangly for my taste. I have this issue with most packs though, to be honest.

Finally, the main drawback is that 48 liters is not always enough space, but then again, there are bigger packs out there for that.

 

Final Thoughts on the Osprey Kestrel 48

Still with us? Well, wow! You’ve just made it through my obscenely long and detailed review of the Kestrel 48, which contained no fewer than 2 expletives, 2 biblical references, and plenty of other nonsense. 

If you actually read all of this, then I think  you owe yourself a little treat. How about an Osprey Kestrel 48?

Seriously, I have now been using Osprey backpacks for a couple of (amazing) years now, and I doubt that I will ever look for another brand. The Osprey Kestrel 48 is perfect for those shorter trips or hikes.

If you are looking for a cool, functional, reliable, light, and awesome valued backpack, then the Kestrel 48 is an ace choice.

    Aiden, thanks for this faboulus review. I’m looking for a backpack which I can use for a couple of overnighters in Holland/Germany/Belgium of dayhikes. That’s whyis doesn’t have to be that large. I tride a 58 ltrs in the show. Feels good.
    But I also have to pack stuff. I have a 1,8kg sleepingbag and a 3kg tent (50x15cm packed). That’s what I already have and I don’t want to spend more just because I have stuff that’s still fine. Sleepingpad is 0,8kg en quite small. What do you think whit these sizes with this backpack. I really like the looks, features en how it feels on to my back, but I don’t want it to be to big and heavy because I also want te do daytrips en weekends with no campingstuff.. for the short overnighters with campgear I don’t have to take a big amount of (warm) clothing…
    Thanks again and goodluck with traveling
