The Basso Pro fly weight bottle is the lightest 550ml bottle available. Its record weight of 54g is achieved through its variable thickness. Thicker on the base and thinner on the central body, this doesn't just make it possible to use less plastic material, it also ensures a tight grip when cycling and an easy to squeeze ergonomic structure so liquid flow is abundant with the lightest pressure.
Material: Specially created polypropylene
Cap: 2-piece cap with removable 1-piece valve for easy cleaning
