You'll stay hydrated with the Showers Pass VelEau 42. It's a unique, bicycle-mounted hydration system, designed specifically for mountain, road, triathlon, touring and recreational cycling. It eliminates the need for a hot, cumbersome backpack-style hydration pack; and is a safer and more easily accessible alternative to traditional frame-mounted bottles. It has a 42-ounce reservoir in a seat bag with room for your gear too. And there's a medical-grade drinking hose that runs from the reservoir to your stem. It's attached via an easy-to-use magnetic reel so you can simply grab, pull and sip from the bite valve to quench your thirst with ease.
