Review on Gelindo 15L Hydration Backpack with 2L BPA Free Water Bladder - Lightweight Outdoor Gear for Hiking, Biking, and Camping - Insulated Compartment, Ideal for Kids and Beginners by Tyler Kota

I really like this water backpack. It holds a remarkable amount of water. The water comes out of the tube very easily (yes, you still have to bite the tip, but that's how they all work). The material is a lightweight, water-resistant nylon but looks of pretty good quality. All straps are comfortable and adjustable. I don't know how well the water bag cooling pad works as I haven't used it for a long time. There is definitely plenty of room for additions. I have a complete bike kit (from multi-tool to headlamp and spare tubes) and still have room when I need it. The only doubt is that it would be nice if he also had a waist belt or lower. chest strap at hand. I had to do some digging in the garage and when I bent over the backpack it slid forward and up my back which was quite uncomfortable. But it's not really designed to be used that way from the start, so it would be nice, but hardly necessary for normal use.
