osprey back side backpack Sportlite 20 Hiking – Shop Escape Outdoors Osprey Sirrus 36 - Walking

Its small, but not too small, comfortable, the pockets and storage are for the most part well-thought out

You can pick from nylon and polyester material options

Its worth noting that the Jester has similarly loose bottle pockets, so this issue isnt necessarily exclusive to the Vault

If you overpack the bag, it tends to round out the back of the pack, making it uncomfortable to carry

Plenty of compression straps, including one inside the bag that compresses the contents from the top, make it easy to keep everything balanced and even offer ways to hang clothes or a towel on the outside of the bag to dry while hiking
