Castelli Water Bottle Red, One Size

There's nothing worse than feeling parched on a long, hot ride. But if you brought along the Castelli Water Bottle, you'd be enjoying a nice, refreshing bottle of water or electrolyte mix. This water bottle features Castelli's Purist technology, which prevents residual taste and stains, while the MoFlo valve is quite easy to open and assures leak-proof performance.
