    Don't weigh yourself down.

    Whether you're heading out for a single night under the stars or an ultralight thru-hike, the Osprey Levity 45 Backpack carries your gear with poise. NanoFly fabric is incredibly lightweight and also resistant to abrasions, so you don't have to worry about bumping a tree limb or rock squeezing through overgrown passages of trail. This pack has Lightwire suspension to give the load structure, keeping it balanced as you duck and scramble as the trail requires. The ExoForm harness and hipbelt pad the contact points for your comfort, while the tensioned mesh backpanel maximizes ventilation between you and the pack to manage moisture. Pockets and attachment points at the top, front, and sides of the pack ensure that you can get to your most-used items quickly so you can get back to crushing miles.

    So light!

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

    I demo'd this bag for an overnight trip down the Narrows in Zion National Park and this thing is legit! I used the men's because it fit my torso a little better than the women's version. This thing is great for lightweight travel! I prefer to hammock camp so most of what I have is pretty light so this bag worked great. If you carry heavier gear then I would recommend you get a slightly heavier bag. If I were going on a longer trip I think I would opt for a slightly burlier bag with a little more features. This bag is an exercise in simplicity and for shorter trips I loved it! The fabric felt like it would be super fragile, but I found it to be pretty durable! And I packed this almost to the brim.

    This is probably the most comfortable suspension system I've ever had on my back with a full load! My only complaint was that when I wanted the straps cinched down tight, the mesh on the shoulder straps left some gnarly marks on my shoulders because I was wearing a tank top. The padding with the mesh over it is NOT friendly to wearing sleeveless tops, so if you like to wear tanks, I think you might want to look elsewhere because I chaffed pretty bad and my shoulders looked like I had lizard scales each time I took the pack off.

    I was given this product by Backcountry, but this review is my personal opinion.

    This is the first Osprey pack that I have owned in a long time and makes me want to give them another chance in the future. I have stayed away from hem in the past because I felt they always overdid it with straps. Certainly not the case with the Levity. It is extremely streamlined and the only zipper is on the brain.


    - Roomy. For a 45L pack you can fit a lot of stuff. The front packet is perfect for easy access to a rain shell or micro puffy, while the side pockets each can easily fit a 1.5L Nalgene.

    -Comfortable. I am 5'8" with a 28" waist and got the small. It fits great. This is my first pack with Osprey's airflow mesh back and it works as well as advertised. The brain is stitched all the way across the top which helps keep it stabilized, too.

    -Streamlined. A minimal amount of straps and buckles makes it easy to get inside of the pack and makes sure that nothing falls out. The only zipper is for access to the brain.


    -Cinch straps. Each side of the pack has a cinch strap that just kept getting in the way when not being used. They were easy enough to untie and remove.

    Overall I am very pleased with this pack and it will definitely become my new go-to day pack. That being said, i also cant wait to take it on some 2-3 trips in the backcountry. I will be sure to update this review once I have.

    Osprey is on to something

    • Familiarity: I've used it several times

    Osprey has found a nice little niche with this pack. Normally packs with UL materials have lackluster frames, and packs with good frames are constructed with heavy material. This pack uses a sturdy frame and light materials to find a sweet balance between comfort and weight.

    -Lightweight, any pack made of Cordura is going to help keep your base weight low!

    -Carries very well. The Lightwire suspension is super comfy and balances weight well between hips and shoulders.

    -Back mesh is verrry breathable. Much less sweaty than any other pack I've tried.

    -Easily compressible when taking smaller loads. Though the frame cannot compress down, the cinch system on this thing is pretty money.

    Not designed for vertical pursuits. When pushing up 35-45 degree talus fields, I found that my head would hit the frame when looking up. If for some reason you were using a climbing helmet with this pack, you wouldn't be able to look up either. In addition, there are no ice axe/trekking pole loops. While this is a pack designed for long, fast thru-hikes, a lot of modern thru-hikers are pushing limits in more vertical terrain like the Wind Rivers and High Sierra. I think it would be smart for Osprey to make it a little more "alpine friendly".

    Overall, I think Osprey is headed in a great direction with this pack. Light materials and a very functional design for long distance treks would make this pack choice for those who value both weight and comfort. I doubt there are other packs on the market under 2 lbs that carry as well as this one.

    Osprey levity 45l

    • Familiarity: I've used it several times

    I’ve gone from the exos 48l to levity 45l to save some pack weight. I have just over 50 Miles in with the levity and absolutely love the pack. My pack weight is right at 18lbs for a five day trip in the backcountry.
