Product Reviews
Rated 4 out of 5 by from Awesome pack! Typical Osprey weird design... Got this guy for a 50 mile hike this summer. Already completed a couple short treks with it and immediately I love how comfortable it is (even with a heavy load). However because of the osprey domed metal frame it definitely sits different compared to any other pack. Was comparing this one with the hyperlight 2400 and a couple others and figured I'd give this one a go. I'm pretty pleased with my decision. However I will say because of the design the pack will always fall over when set down... just a little gripe I have. But given the weight and the breathe ability of this pack I highly would recommend this guy for those looking for a lightweight weekend or week long hike. P.S. Highly recommend the matching osprey waterproof cover for this bag... it's definitely not waterproof by itself like the hyperlight...

Rated 5 out of 5 by from exceeds expectations got this pack for the colorado trail and beyond. at one point carried 7 days worth of food in this little guy. exceeded the load weight by at least two fold, still felt great. for a sub two pound pack, this thing is amazing. surprisingly durable and going strong two years later. for an ultralight pack it doesn't sacrifice comfort, that's why i chose it. for the right intentions and use this pack is far above anything else i have used.

Rated 4 out of 5 by from Can't believe they put a fixed top on a thru-hiking pack This is a nice long-distance/ultralight pack with one Achille's heel. The main packbag is a versatile, common design nowadays. The front pocket and big side pockets are nice for quick access to gear, and surprisingly carry quite a bit. The silnylon, while thin, seems like it will hold up well as long as you pay a little attention to it. The thicker fabric in higher-wear areas inspires more confidence. Overall it carries pretty well, though it has a tendency to slip down my back at the lumbar, and I would gladly trade a couple ounces for a full, more padded/structured hip belt. I've thru-hiked the PCT and AT, and nearly every other thru-hiker I've known gets rid of the top lid on their packs. Very sadly, Osprey doesn't give you that option with this pack, and the fixed lid drives me nuts. I'd much rather save those ounces (and have them in the hipbelt) and have quicker access to the drawstring into the main compartment. It's a shame because otherwise this pack would be perfect. FWIW, I like the color of it too, much preferred to the gaudy Exos series colors.

Rated 5 out of 5 by from Nice, Light-weight Pack I bought the Levity 45 for a week-long hike on the Georgia section of the AT. It was the final piece in my efforts to reduce my pack weight from 40 lbs to 25 lbs or less (I succeeded). I found the Levity more comfortable than the Exos model I had intended to buy, so I bought the Levity, instead. and after purchasing a compression sack for my down stuff (hammock top & bottom quilts), I found the pack was the right size for carrying all my stuff. Things to note: - the front-opening side pockets give very easy access to water bottles, and they seemed the perfect size to stack two 700 ml SmartWater bottles in each pocket. FYI: if your half-empty bottle starts making a sloshing noise, reach back and tilt it up a little bit... problem solved. - while some folks don't like lid pockets or "brains", this one's fine: it's not overly big and is firmly attached to the back of the pack, so it doesn't flop around like some do. Keep some items in it that you want easy access to and that are not too heavy, and you'll probably appreciate having it, too. - the pack's weight tended to ride on the area between my waist and the top of my butt, and if I shifted the weight up, it eventually found it's way back to the same place. It was a comfortable carry, and I think mostly a matter of me being a guy without much in the way of hips, rather than anything to do with the pack's belt, etc.. My hiking buddy had a far more robust pack, and he tended to re-shift his pack weight at least as much as I did. - Fully loaded including food and water, my pack weighed about 25 lbs, and it carried fine. I certainly didn't feel like I needed "more pack" to haul the load. As the contents of my food bag emptied and I was carrying about one liter of water, my pack weight was probably about 20 lbs, or maybe a little less. At that weight, this pack was an absolute dream to carry... it seemed to almost disappear on my back.

Rated 3 out of 5 by from I really wanted to love this pack, but... I was hoping they would revamp this backpack for 2019 but sadly no. First the good: Ultralight. Love the weight. Very comfortable. Some backpacks hurt my back. Not this one. Now the bad. The brain is permanently attached and does not adjust up. So you can't remove it. Top does not expand up. Bummer for through hikers. No external pockets. They could at least make them an add on accessory. Outer storage is not made of mesh and doesn't expand. This is a real bummer. Takes two people to get your water bottles out. The pack falls over when you set it down. Seams to attach dirt. I took this pack on one hike 3 days, 2 nights and returned it. So comfortable. But when you can't even get your water bottles out. So frustrating. If they made the brain removable, mesh side and back storage, make belt pockets available this pack would go from a good first attempt to a great pack.

Rated 5 out of 5 by from Levity Pack I just completed a one week backpack trip in the Trinity Alps Wilderness. The pack was the lightest I've ever used. I found it to be adjustable as needed and comfortable beyond comparison. I've been backpacking for over 40 years. This is the most comfortable experience I've ever had with a backpack. I also appreciate knowing that I can call Osprey with questions and speak with a human.

Rated 5 out of 5 by from Comfort and extremely light I am Almost 50 years old , can still get 15 mile days in thanks to the help of this light weight pack . so very comfortable . find no need for extra pockets as I use a hydration reservoir , use side pockets for snacks that you can reach as you hike . My favorite pack for 3 seasons , been a avid backpacker approaching 40 years , can not go wrong with this pack , you have to remember what this pack is designed for , love it.

Rated 5 out of 5 by from Osprey does it again [This review was collected as part of a promotion.] It's an awesome light back pack. I bought for my brother. I packed it with a tent and few other heavier items and he said he was 'light as a feather'

Please note that the info provided above refers to the Torso Size / Length the pack will fit, and NOT any dimensions of the pack. Below are steps for how to measure your torso length. You should have someone help take this measurement for you so it is accurate.

1. Start at the iliac crest, which is the top of the hipbones on the side of your body. These act like a shelf for supporting a pack hipbelt.
2. Touch your chin to your chest to find the C7 vertebrae, the knobby bone at the base of your neck.
3. Make sure you keep your back as straight as possible while measuring.
4. Measure the full length from the C7 vertebrae to the iliac crest. This torso measurement determines what size Osprey pack you should carry. Refer to the size chart above to find your ideal size.
5. If you are in between sizes, it is ideal to try them both on before ordering.

Measure around the fullest part of the chest.

Warranty Info

ALL MIGHTY GUARANTEE - Osprey's Lifetime Warranty

When Osprey celebrated their 35th anniversary in 2009 they launched The Osprey All Mighty Guarantee. What that means to you is ANY Osprey product purchased at ANY time is covered. Any product, any reason, any era - the all encompassing Osprey lifetime warranty ensures their dedication to superior design, craftsmanship and quality of their products is backed up by their actions to replace or repair a pack so it lasts a lifetime. Or two.

Here are some details.... Osprey will repair for any reason, free of charge, any damage or defect in their products, whether it was purchased back in 1974, or ordered right now from this site. If they are unable to perform a functional repair on your pack, they will happily replace it. Osprey proudly stands behind the All Mighty Guarantee, so much so that it bears the signature of company founder and head designer, Mike Pfotenhauer.

Some Osprey All Mighty Guarantee FAQs:

What do I do if my Osprey pack needs to be repaired?
If you live in the United States and need a repair done on your Osprey pack, you will first need to obtain a Return Authorization number. You can do this by reaching their Returns Department at 866-314-3130, or using the information that is provided with a new Osprey pack.

What do I do if I just need a replacement pack part like a buckle?
Give Osprey a call at 866-314-3130 and they will take care of you.

How long will it take?
You can tell Osprey you need the pack returned by a certain date when you request a Return Authorization number, and they will do their absolute best to meet that deadline.

What if my pack is super dirty and stinks?
Clean it before you send it to Osprey to get repaired. The real reason is that there is a law that says if your gear is too dirty or odiferous (smelly), Osprey is not allowed to repair it and will just return it to you.

Do I have to pay for shipping?
A little bit. You are responsible for the cost of shipping the pack to Osprey, and they will pay shipping to return the pack via UPS or FedEx. Osprey cannot be held responsible if packages get lost in transit, so make sure you get a tracking number when you ship your pack out. Also, if you use expedited shipping be sure to let Osprey know (866-314-3130). They, in turn, will give your pack priority processing and return it using a similar expedited shipping method.

Do I have to register my pack to take advantage of this incredible guarantee, and/or need to be the original owner of my Osprey pack?
No! Osprey's All Mighty Guarantee is truly ALL MIGHTY. If you own an Osprey pack that needs to be repaired they will repair or replace it.

JUST A HEADS UP: If your Osprey product is not repairable and is replaced, the original product will not be returned to you. They will try really really hard to repair your pack, but if they are unable to make a functional repair, they will replace it. For products that are no longer in production you will be contacted by Osprey to discuss replacement options.

All good answers. So what is NOT covered?
• Osprey program packs or any Osprey pack used by outdoor programs are ONLY covered under Osprey's Program Pack Warranty, NOT AMG.
• Size and/or fit issues. Make sure you buy a pack that fits. Check out the size guide on Osprey product pages for more info.
• Personal preferences like colors you don't like, style of the pack, or not enough/too much room in your pack. Check the product description, features, specifications, and size guide to make sure you are ordering the right pack for you.
• Third party Repairs or replacements. Send your Osprey pack to Osprey and Osprey only to get fixed. Easy as that. And don't try fixing things yourself.
• Cosmetic wear and tear including any reasonable aging of your pack that affects only the appearance and not the function of your pack. Be proud of those scars!
• B.A.M.G. (Before All Mighty Guarantee) Repair Work. The All Mighty Guarantee applies only to repairs requested on or after January 1, 2009.
• A Osprey Hydraulics reservoir is covered by a limited 1-year warranty, which is the reasonable lifespan of a reservoir. Pouring and storing of warm/hot or boiling water in your reservoir WILL VOID your warranty, so don't do that. Reservoirs are NOT designed to contain or handle liquids at temperature.
