Designed with an angled spout, Camelbak’s Chute 0.75L delivers a high and steady flow of water without spilling down your chin. When drinking, this cap simply clips into place to prevent it from getting in the way. Camelbak have attached the cap to the bottle through the inclusion of a rubber tether which securely keeps the bottle and cap together at all times. For cleaning purposes, all parts can be unclipped to be put into a dishwasher and are also BPA free.
