Outer (front) stretch pocket
As you can see, the fabric is very stretchy. I used 2 32oz bottles for example.
Do to the new linelock compression straps that go across this pocket, I am no longer able to strap my z-rest here vertically. On the Nimbus Ozone and the Vapor Flash, this was the perfect place for attaching it. The linelocks apparently cannot be quickly removed and re-attached easily.
