Why We Like The UNLTD AntiGravity 64L Backpack

The UNLTD AntiGravity 64 Backpack is a big step up in packing technology. Osprey looked at every nook and cranny when it came to designing this stable and easy-access trekking bag. That all starts with the UNLTD AntiGravity suspension system—utilizing vertical and horizontal wire steel framing, a formed back panel, and a Carbon DLS secures even the heaviest hauls to the center of your back to become one with the bag. And even more than that, the UNLTD AntiGravity's highly adjustable setup can be tuned on the fly thanks to the easy-grab straps. So if it's ever feeling loose, just cinch it up and keep pushing forward.

Really feels like nothing on your back

I've used it once or twice and have initial impressions
Size Bought:

My husband and I both have these. He scored his on sale for 50% off at a local gear store and I got mine on sale here. Probably not worth the non-sale price. I upgraded from a 54 L backpack to this and it truly is comfortable! I was previously wearing an older Osprey Atmos. I love the clamshell opening for packing purposes AND for accessing your gear on the trail. I got a really nice fit and never had any pain in my hip bones or my shoulders.
