With a capacity of 500 ml, the Sense Pro 50 bottle shape is designed for frames that lack space and access. Its over-moulded cover offers better grip on the bottle and its double-closure Pro-Cap system makes it 100% watertight for easier carrying. No more spilled drink on the bottle and on the bike! The silicon push offers a pleasant sensation when drinking. The quick-opening valve provides better-regulated control of the liquid consumed without spillage due to overflow.
