This under-the-seat system makes fluid intake on the go simple.

The 42-ounce reservoir fastens below your seat.

The bite valve offers enough suction to successfully bring water from the back to the front of the bike without any extra effort, and we were able to easily bring the tube to our faces or lower our heads and sip, hands-free.

When filled, the VelEau 42 added 3.73 pounds to our bikes, which is on par with carrying the same volume using other methods.
