The USWE Rocket Softflask With Straw delivers hands-free hydration through a longer straw, so a runner can drink without breaking stride or digging for a cap mid-race. The flask sits deeper in the vest pocket than a standard bottle, which keeps it out of the way and cuts down on bounce with every stride. Made by HydraPak, the collapsible TPU flask flattens as it empties, so there's no half-full sloshing to distract from the trail. What Our Gearhead(R) Experts Are Saying:"I can grab the straw and drink mid-stride on a technical descent without ever looking down, which matters more than people expect once the trail gets rocky."
