Nathan design and quality in an intuitive pack, the Nathan Triangle hydration pack is perfect for runners and walkers of all levels.
Comments: Pretty good product overall. Use this along with hand bottle for my ultra training and racing. Once adjusted correctly it's very comfortable and hardy noticeable. Love the bungie over the bottle that practically eliminates bouncing. Only down side is that since it is not a stretchable waistband you have to fit it pretty tight to stay still.
