Go big. The largest of our ultra-light series, the UltraFlask Speed 6 ml holds more so you can go the distance. Its soft material allows it to fit snugly in most vest pockets and it shrinks as you drink to minimize water movement. Topped with our newest SpeedFill? cap feature that makes aid station refills a breeze.
