The Breakaway Surge&';s beauty is its simplicity. The lightweight performance design starts with our Surge(TM) Cap - self-sealing, it delivers high-flow hydration on the move. The bottles are slim and ergonomic to fit comfortably and securely in your hand and cage, and the ultrathin side walls make squeezing easy, so focus stays on the ride, not the bottle.
