Review on Hydration Adjustable Climbing Lightweight Waterproof by Anthony Morrow

I've never carried a water bag while running but with the hot summers I figured it would be better to run with something other than a water bottle in hand. I've been out for a long time this weekend and I can honestly say I hardly noticed it was on my back other than the cold from my ice cream. As a beginner with a backpack I wasn't sure how tight I needed to make the straps so I just tightened them as tight as I could and I must have been lucky the bag didn't move afterward. I wish there was a guide on how to care for the bag, but it's not that difficult to understand. Assembly wasn't too difficult either, you have a choice of which side you want the straw to come out on.
