“I am usually a water bottle only type a guy. When I got the Fluid Pack, I converted. The way a hydration unit is contained in the pack, along with the contours of how extra gear is packed around it, simply worked. I could hike, drink, and my gear did not affect that water flow, which I have had a problem with in the past. I now use this pack as an all in one hydration system and gear transport as a single unit, and never stop to get out my water bottle. It’s like I gained a new engine with fuel injection.”
