    Shave ounces without losing out on comfort and stability.

    Putting shoulder straps and a belt on a silnylon sack might be super lightweight, but without real suspension, it's hard to haul when your load breaks the 20-pound barrier. Osprey created the Exos 34 Backpack with a lightweight yet sturdy aluminum frame so the Exos can transfer slightly larger loads than other minimalist packs. A breathable foam back panel and mesh hip-belt help circulate air to improve evaporative cooling.

    Awesome Pack

    • Familiarity: I've used it several times

    Really digging the pack. As a diehard Osprey fan (I rarely cheat on them), I used a Kestrel 32 for a long time for day hikes and over-nighters if I was with other people, and although it still is the most comfortable pack ever, I wanted something a little lighter and with more breathability for warmer weather (I get very sweaty and often find myself carrying packs on one shoulder to dry off, not Osprey's fault, just me).

    Without going into detail, I chose this over the Stratos for a few reasons, but I'll admit that I did NOT like the Exos series when I first saw it (when I was still judging the book by the cover). It seemed very fragile and I didn't think the shoulder straps sewn on the tension mesh would hold up. Well, I was wrong, and Osprey deceived me in a good way. After a lot of usage and some minor abuse, it shows no signs of wear. As long as you have more than 10 lbs in the bag, the mesh hugs your back like a glove and helped me significantly with sweat reduction. The Airspeed suspension system with the tension mesh isn't QUITE as comfortable as the Airscape for me personally, but it still is incredibly comfortable and worth the small trade off for the breathability. Take that statement with a grain of salt, it's still more comfortable than 99% of the other packs out there, but if sweat was not a problem, I might choose the Airscape by just a hair. But let's face it, there's no perfect "do-it-all" pack out there.

    Also, I tend to only use hipbelts on descents, so on the way up, the Exos' hipbelt easily folds backwards around the pack and stays put if you loop it through the side compression straps. The only minor issue with not using the hipbelt is that the pack tends to shift on your back slightly with each step, which can get a little noisy. Not a big deal as I understand the pack is designed to secure around your waist, but my Kestrel does not shift without the hipbelt. Perhaps unavoidable with a tension mesh suspension, but just more of a comment rather than a complaint -- figured I'd just mention that.

    I remove the lid for dayhikes, and put it back on for over-nighters (both for weight and volume reduction). Without the lid, a simple sewn-in flap deploys to cover the top of the pack and you basically just have one big compartment -- I prefer to use little organizational pouches rather than pockets built into the pack, so this is how I like it. I was a little concerned that 38 liters may be too big for a day-hike, but without the lid (which is 6.5 liters for the Exos 38 in Medium, info directly from Osprey), it goes down to 31.5 liters, in case anyone was curious. The ability to remove the lid it makes it quite versatile.

    On a quick side note, I really like the way the outer pockets are designed. I love the little pockets on the shoulder straps -- great for little items you use frequently (I put my vaping device in there!). The side pockets are also well-placed. I use one of them for my fairly large smartphone because I can easily take it in and out from the front opening of the pocket without taking my pack off. So far it's never fallen out, but if I was moving fast or on fairly rough terrain, I might suggest putting it inside the pack to avoid problems.

    Overall I'm extremely impressed with this pack and have no real complaints at all so far. Really makes me realize how over-built some other packs are, and you gotta admit, it's pretty badass looking. The only reason I'm upset is because I judged this pack without trying it and didn't buy it sooner. Plus, I know that if anything ever goes wrong, Osprey's got my back. Oh, and great service from Backcountry as always!

    Great pack

    • Familiarity: I've used it several times

    I took this on a few weekend hikes in the Whites, as well as a few other over nighters during the summer of 2015. After using an older pack for many years, I was blown away by the light weight and air frame of this pack. The airframe doesn't really stop you from getting all sweaty, but it is very comfortable and helps cool you down to a degree. The hip belt and other adjustable pieces make for a comfortable, sweet fit. I bought an Osprey bladder (3 liter I think?) and it fits and works great with the pack. My one quibble is the sizing of this thing. I got the large after measuring my torso as instructed by the sizing chart on the Osprey website. The large is just a tad too big, which can lead to very annoying chafing spots over the course of a four day march. I should have gone to an EMS or REI to try one on before purchasing.

    Hey there - you are right, the frame cant stop you from sweating (hard to do!), but it can dry you off quickly. Yes, sizing is non adjustable, because adjustable sizing adds weight. And in this pack, we wanted to strip everything that added weight. It's important to not think about your height when considering size. It has to do with how long your torso is, so sometimes tall flks have long legs and short torsos, so trying it on is the best way to go.

    Glad you like your Exos!

    Great ultralight option for multi-days

    • Familiarity: I've put it through the wringer

    I was suprised at just how much you can cram into this little guy. Still had plenty of room after packing in a fairly large sleeping bag, clothes and layers for several days, full cookset, fuel, food and toiletries. Didn't even get close to hitting capacity. Easy to load, comfy to wear, all the technical and adjustment features of the full-size Ospreys without the bulk and weight. LOVE the new hip belt adjustment system. Much more intuitive, easy to use and adjust on the fly.

    Awesome Use of Materials & Super Design

    • Familiarity: I've used it several times

    It's difficult to decide which ultralight bag to pick ... A very personal-preferences decision for sure, however, Osprey Exos makes that choice a little easier with it's versatile design, quality materials and nice light-weight frame and ventilation system. Super comfortable and stable when wearing, plus greater durability than others in this category. Makes a great daypack and helps you make the right choices in equipment to keep your base-weight down on overnight treks. Can't go wrong with this one!

    Does anyone know whether or not I can use Exos 38 as a carry-on when flying? Thanks.
