Review on Gelindo Tactical Hydration Backpack: 2L Water Bladder, Lightweight Pack for Hunting, Hiking, Camping & Cycling by Bryan Turner

Originally bought for a snowboard I wanted and it worked great. I don't know if it's waterproof or not but it held up well in the snow and kept everything dry. I then used it on a week-long trip to Brazil, where it proved even more useful. I didn't even buy it for the insulated water pouch, but I stored a water bottle in this pouch for hours in 100 degree Brazilian heat and it stayed damn cold all day. I'm glad I bought this.
