Review on BPA-Free PEVA Hydration Pack Bladder - WACOOL 2L/2Liter/70Oz Or 3L/3Liter/100Oz Capacity, Leakproof Water Reservoir by Julian Locklear

This is the first bladder I’ve purchased and it worked very well. Did not have a problem with leaking at all. Fits enough water for longer 12-15 mile day hikes. The only thing that was difficult to figure out at first was the mouth piece. There are not clear directions for this. To get a steady flow of water you have to pull the base of the mouth piece out after you take the cap off, twist it in the designated direction, THEN bite down.
