    A lightweight weekend backpack that will please some of most minimalist adventurers out there.

    The superlight Osprey Exos 48 Backpack has enough space for all your gear for weekend backpacking trips in the Uinta mountains in the summer or the Ouray Ice Park in the winter. A combination of the AirSpeed back panel and the light yet durable 6065 aluminum frame brings a lot of breathability by dumping excess heat out of the sides. ExoForm covers the shoulder pads and waist-belt with mesh and gel for the ideal blend between breathability and comfort while you hike. This top-loading pack features a removable lid with two zippered pockets for short day hikes during your trip.

    The Exos 48 also features two mesh side pockets for water bottles, two zippered pockets at the waist-belt for any small item you might need on the trail like sunscreen or lip balm, and a front stretch mesh pocket for quick access to maps, a book, or a compass. It also has straps for a sleeping pad, and you can remove both the sleeping-pad straps and the compression straps when you're going minimal. There's an attachment loop for an ice tool or two, and a tie-off point for a last-minute item.

    As far as I know the best pack ever made

    • Familiarity: I've used it several times

    Let me preface my review by admitting that I've not carried that many good packs in the field. Most of us haven't. But I know what I have carried and how they felt.

    If I had unlimited funds to buy any pack made this is the pack I'd choose. Apparently a lot of people think the same way because this pack shows up in almost every "best pick" article I've ever read.
    The cooling effect of this pack's design is phenomenal. The load handling and comfort is...well, I don't think it could get any better in the 19-26 pound range that I hike in.

    The pack is light, but not so light that you question it's abilities. It's probably as close to ultra-light as you can get without running into the issues that ultra-light packs are notorious for. I have not carried 35 pounds in this pack (and likely never will), but I have no doubt that it'll handle it like a champ. It transfers weight to my torso better than any pack I've ever tried on (and I've tried on a bunch with weight bags in local outlets). I mean like all the weight is on my torso. I'm just blown away about that. Being a lightweight pack it doesn't have a bunch of pockets. The compression straps are very thin. I'm sure they'll hold up over time, but I do wonder.

    I wish it had a pack cover. Having experienced the weight gain of a soaked pack I endeavored to and succeeded in getting all my gear into my pack rather than lashed to it for the express purpose of being able to use a cover. Now that I have this pack I'm relying on a poncho, which admittedly works. Still I'm fond of a pack cover and may have to splurge for Osprey's premium priced offering. Incidentally, the reason I like a pack cover (a poncho is actually better at keeping my pack dry) is because in the Arkansas heat it's sometimes nice to get rained on. Maybe that's just crazy talk.

    Of all the gear that I've ever purchased and reviewed for hiking there is no other item that I can more confidently and enthusiastically recommend than this pack.

    Excellent light weight pack

    • Familiarity: I've used it several times

    I have made numerous backpacking trips and bought the Exos 48 as part of going lightweight. I'm very pleased with the pack after completing 1 week in the Winds in Wyoming and plan to use it for section hiking in the Appalachians.

    Good bye weight!

    • Familiarity: I've used it once or twice and have initial impressions

    This is my first experience with a light weight pack. I've been using a Gregory Baltoro 75 for several years and have always really liked the fit and function but over the last year the weight of my sleep system and clothing have dropped to the point where my Baltoro had become overkill.

    So I picked up the Exos 48 and headed out to Rae Lakes for a few nights in the Sierras. The Exos topped out at about 28lbs with food and water. At that weight it was absolutely amazing. The frame and shoulder straps made the weight disappear. The design provides great air flow so my back was actually cool in the hot summer days. The biggest surprise is how convenient the pockets are. As much as I like the Baltoro,the Exos works better. Pulling a liter water bottle in and out of the side holster pockets is easier on the Exos even though the Baltoro has a dedicated holster. The Exos shoulder strap pocket is perfect for an iPhone. Also the large central pocket is great for the items you need quick access. All of these little features make the pack work really well.
    Like other pieces of light weight gear, care needs to be exercised when using the Exos. The materials aren't up to being dragged across granite and packing sharp gear needs to be done with care. Those that can't master the zippers found on light weight tents and bags may be a bit ham fisted for the Exos.
    All-in-all I'm very pleased with the Exo and surprised with how well it works. Osprey knows how to design a pack that works.


      ...Do it again (stupid iPhone) instead, I just kept going and never took the pack off! When I had just about completed the 5 miles I realized my sunglasses had fallen off the strap. So I backtracked another mile or so and actually found them! They are pallets after all! I ended my little morning hike with my brand new exos loaded with 22 lbs of gear, water, and food having covered 6.5 miles. Not bad for this 58 year old body! Now to double that and do 3 or 4 days in a row.

      Awesome Pack as Expected

      • Familiarity: I've used it several times

      I got this for weekend camping trips and I've come to expect top notch quality from Osprey as this is my 5th pack from them. The bag is extremely light weight, has all the features you can imagine, and shrinks down to fit your load perfectly. I tested out the waste strap and i would say it would remain comfortable up to around 45 pounds, which is a lot for this style pack.

      Great pack - Super light

      • Familiarity: I've used it once or twice and have initial impressions

      Obviously, it's light. You knew that already, the pack fits great. The hip belts are quite comfortable for how small they are (compared to the other Osprey Packs).

      The suspension system is amazing, feels so nice when a cool breeze is running between your back and the pack.

      Light, Light, Light!!!

      • Familiarity: I've used it once or twice and have initial impressions

      Hopped on the Osprey bandwagon and darn glad I did. Loving the additional storage space and the bedroll strap. I haven't used it on any long trips yet but look forward to it,

      What an internal frame pack should be

      • Familiarity: I've used it several times

      This pack is right on point down to every little detail. The mesh panel really does help your back breathe better than most packs and reduces the dread back sweat as much as possible. The frame is lightweight but still supportive and is definitely not flimsy. The nylon is lightweight but you can tell it is not going to tear any time soon. The detachable lid and infinitely adjustable suspension are two of my favorite features.

      At hardly over 2 lbs this pack is almost in the category of an ultralight but it will hold all your gear just as if not more comfortably that your old full frame pack that weighs over 4 lbs or more.

      If you want to shed some weight from your pack itself without any comprise in support then you have found your pack.

      You also cannot beat Osprey's warranty policy if you were to ever have an issue. The Almighty Guarantee is second to none.

      No seriously, they said replace for ANY reason ANYtime, no that is not a typo and no they wont hassle you for ANY reason.

      This pack is everything I wanted it to be and more with new snazzy details I notice every week I go camping!

      Wow just Wow and more WOW

      • Familiarity: I've put it through the wringer

      Yes, this pack is that good. Do you want to shave all the weight and keep all the features then this is the pack for you! You will love the way the pack is framed it never touches you middle and upper back! The waist best has no extra straps hanging down and fits like a dream! I have my winter pack weight down to 24 with 2 liters of water and its like I have nothing on my back at all. I love how versatile this pack is. If you want to go out on a 2 or 3 day trip it will handle all of your personal load! I you want to take it ice climbing or mountaineering it will carry ice axes and ropes. Its is the perfect pack for other of us that count the ounces!! There is not one thing I could ever say bad about this pack!

      Upgrade over the old version

        I've been using the older Exos 46 for the last 2 years and its the best back I've ever owned, mainly because of it's light weight, breathability and overall comfort. I just checked out the new Exos 48 at EMS and it looks similar to the old pack with some noticeable upgrades. Also, the updated colors look fantastic. The most noticeable upgrade is the padding on the shoulder straps and hip belt. The old models sacrificed padding in this area, I'm guessing to make the pack lighter and more breathable. Osprey did a great job of adding "meshy" breathable padding to the new pack without adding much in the way of extra weight. It's only a few ounces heavier than the old model, yet it is more spacious and has detachable straps that allow you to make the pack lighter than the old model if you so desire. Either way, the weight difference isn't noticeable unless you put it on a scale. As comfortable as the Exos 46 is, the new model is even more comfy! The rain cover is also a new, welcome feature. Excellent job by Osprey improving one of their best packs. I'm tempted to buy the new one even though my old one is still in great condition.

        I have a full size BearVault. Would it fit inside? How well?

        The back panel has some lightweight rods to add support, so they wont bend or fold to fit in the canister. Are you looking for a summit pack that would?

        Feel free to hit me up at or 801-736-6398.

        If I have a 42 waist will this Exos 48 hip belt fit me?

        Hey Allen Culbreath,

        As for the hipbelt on the Exos 48, all sizes (S, M, L) should fit you. The more important measurement will be the Torso Length. You can reference the size chart on the website, or contact me and I'd be more than happy to help you with sizing.

        I presently have an Osprey Exos 46 (M),...

        I presently have an Osprey Exos 46 (M), and it is PERFECT . . except for the fact that my Wild Ideas Bearikade Weekender (9" diam at the base, 10.5" L) will not fit inside the pack. I am considering purchasing the Osprey Exos 58 for a 19-day JMT trip in August, but I would like to know if you can tell me whether the 58 will accommodate my bear canister. I am very short waisted, and do not like it when a pack is so tall that it knocks my broad-brimmed hat rim forward on my head. Help!
