Great pack
I love the improved valve! It's easier to use and allows more use. The pack has a ton of storage space for phones, keys lunch and snacks. The pack is also comfortable.
My only obstacle is the hose. It crosses the front of the body which is somewhat awkward and at times the magnetic is not strong enough to keep the hose in place. However, I would buy the pack again mainly because of the storage and the convenience of the bladder and the valve.
