The unique low profile design of the Amphipod Full-Tilt Velocity eliminates the discomfort associated with traditional bottle packs; includes a comfortable horizontal riding 20 oz ergonomic bottle.
Comments: Great product. I think this simpler version is actually far superior to the AirStreth version that costs more. The carrier and bottle are very comfortable and do not move or shift at all. There is just enough room in the storage for a few gels and a cell phone. Simple, comfortable, convenient... From: Texas
Comments: I use this bottle on all of my long runs. It fits snugly with minimal bounce. It has a wide mouth which makes filling and cleaning nice and easy. The zip pocket provides ample space for a couple of gel packs. It is very comfortable to wear. From: Kat, New Hampshire, USA
