By combining supremely advanced fabrics and leading design techniques, Levity represents the pinnacle of performance in ultra-lightweight packs. Comfortable, supportive, ventilated and durable, these packs are built for the adventures where every gram counts.
Levity 45 is designed with purely the essential features, in order to minimise weight and maximise performance. A large main pocket with top drawcord access is covered by a fixed lid, which features a spacious zippered pocket. A front pocket provides space to store and easily access spare clothing, while two side pockets will comfortably accommodate water bottles. Loops on the top, front and base can be used for lashing excess items to if needed.
Levity features a fully ventilated Ultralight AirSpeed™ suspended mesh backpanel, keeping you cool and comfortable on the trail. The ExoForm™ hipbelt and harness provide excellent padding and highly effective load-transfer into the body’s strongest muscles.
Advanced NanoFly™ material are used on the exterior of the pack in order to provide impressive durability and abrasion resistance. Non-exposed surfaces are built from 30D Siliconised Nylon, which provides an excellent weight-strength ratio.
Levity 45 is compatible with all Hydraulics reservoirs and size Medium Ultralight Raincovers.
If you’re looking for ultra-lightweight performance without the usual compromise, look no further than Osprey’s Levity.

Brilliant ProductI bought a Levity 60 through your second life site a few years ago, and I am very very happy with it. I am a DofE assessor as well as busy completing my ML. Needless to say I spend allot of time in the mountains. If I am completing a several stage / day hike, this is my go to bag. Ultra light weight, more than enough space, very comfortable. Basically it does what it says on the tin. If I had to knock it, my only criticism is that I cannot store my walking poles on the shoulder strap like you can on my other Osprey bag. I have just seen a 45 on sale and am seriously contemplating getting it.

Great in theory - but it does NOT last!I really wanted to love this pack. If you look at the specs this pack is just superb: incredibly low weight (i.e. in the Dyneema packs territory) WITH a frame WITH a full ventilation system. So far so good. The only problem is that in order to achieve that incredible weight there has been a major compromise in terms of fabric (particularity the UHMWPE). This means that after every single trip I took with this pack I always come back with that little extra tear and I am now running low on repair tape :). So unless you don't care AT ALL about durability, do not go with this and simply upgrade to Dyneema or go with an Exos instead.

Countering Mike's score of one star because he won't download an App!I don't know, either. However, it seems totally unjust for Mike to give one star (and therefore 'sway' the overall score) by giving one star - not for the standard of the product but because HE cannot be bothered to download an App! If Mike had given an average score based on those so far it might have been a bit more reasonable; laternatively, desoute the web page saying "you're reviewiong: Levity 45", Mike still thought he was reviewing the web page, not the product! I'm kind of surprised that Osprey leave it sitting there unless it's as an everlasting reminder of Mike's presence without which we'd all be much worse off.

no idea, can't measure itHow can I select the right size without downloading your sizer app? I am not going through the hassle of downloading an app just to size myself. I will just have to buy another pack unless it's possible to size myself without bothering with the app.

Un Sac surprenant, idéal pour les "Backpackers" qui cherchent la légèreté.Je suis parti sur l'île de La Réunion en ce mois de septembre pour découvrir la vie créole à travers le GRR2. C'est un sentier de grande randonnée qui traverse l'île de part en part, de Saint Denis (Nord) à Basse Vallée (sud de l'île)
Environ 140 km pour découvrir Le Cirque de mafate, de Cilaos, Le Piton des Neiges, Le Volcan de La Fournaise et ensuite le Littoral.
Le sac de 45L est très léger et dès que l'on a bien comprit le fonctionnement de chaque sangle, chaque poche cela devient un véritable plaisir.
L'accès au contenu principal est rapide, mes 2 poches à eau étaient disposées dans la poche extérieur et facilement accessible pour être remplies. Des accroches extérieures sont possibles et facile. La solidité du sac, rien a redire, Rien a craqué. Il faut faire attention, être méticuleux et prendre un peu soin de ces affaires et alors tout se déroule a merveille.
J'avais une "raincover" pour protéger le tout de la pluie. Les bretelles sont à mon goût suffisamment rembourrées, je leurs reprochent juste ce petit détail, pas de passant pour les mains afin de soulager un petit peu les épaules. Au niveau du dos, il est aéré via un filet. Un autre petit détail, le sac ne tiendra pas debout tout seul mais on s'y fait assez vite et on s'adapte. Bref J'adore mon compagnon de voyage et il a été fidèle.

Levity 45Me and my girlfriend we are very happy users of Exos 58 and Exos 48 (mark I) backpacks, we love them for their breathable and very comfortable mesh back panels, large side and front mesh pockets, and many little tie outs, compression straps etc. And as we are downsizing our hiking equipment I was delighted when the new Levity was released. However I got a little disappointed when I got to try one out. Just like the new Exos 2018 (mark II) version I am missing the hip belt pockets. I know it is some extra weight but we find them very useful for all those small bits like trekking pole tip protectors, compass etc. etc. OK, we could live without them but I would find it very useful at least if they were available as an optional extra piece of gear to buy.
But what I am missing much more are the side and front mesh pockets (just like the EXOS mark II backpacks that have less mesh than mark I). I believe there is a reason why you decided to make Levity side and front pockets from rigid fabric, but it stopped me from getting the Levity packs for us. The “old” Exos I mesh pockets hold everything in its place safely. Each side pocket is big and strong enough to carry even 2pcs of 1,5L pet bottle (we regularly carry just one in each pocket but sometimes you need to carry more water). And the front mesh pocket is more importantly perfect for all the wet pieces of wear and gear allowing them to dry out while walking.
I am sure you are doing your best when releasing new backpacks or new versions of the old ones. I am also sure you have experienced hikers to test them in advance. And I am also well aware there is no backpack that meets everyone’s expectations. But it there was a perfect Osprey backpack for me it would be the new Levity with side and front mesh pockets, hip belt pockets (even optional extra piece of gear would be fine) and also I would find it great if some extra straps of the same color were available for example for strapping a sleeping mat outside the backpack when needed.
And I also dream of Osprey back pack with roll top closure… but I can happily live without that :-)
I will keep my eye on your web side time to time and maybe one day :-)

A good pack but some nigglesThis is a great, lightweight and very comfortable pack that seems durable with the right care. However, I found there were some niggles for me and I had t ask many questions at Osprey. The compression straps don't seem that useable I think elasticated straps would have been more useful and I couldn't get them to work in a useful way despite asking Osprey for help. I think they need to do a video if this is to be deemed a useful function at present. Sack falls over onto its front so you need to be mindful of this, and I could not alter the sternum strap - again I had to ask and apparently is moveable however its very tight and I feel like the buckle wont go over the small hoops so have not managed to adjust this as yet. I think if there was a bit more support and information for these basics that would be good. The niggles and lack of knowledge available keep me from giving it a higher rating.
