"What Our Gearhead® Experts Are Saying:""This flask is my favorite for long trail runs—soft enough to collapse as I drink, but structured enough to slide easily in my vest. The SpeedFill cap is quick to use at aid stations, and I really appreciate that it's filter compatible for backcountry miles.""When we’re logging miles on rugged trails or toeing the start line at an ultra, the UltraFlask Speed 500ml Water Bottle keeps us moving light and hydrated. Designed for seamless integration with most running vests and packs, this flask conforms effortlessly to its pocket and our movement—no bouncing, no sloshing, just smooth sips on the go. With a wide SpeedFill™ cap for fast topping off and a soft TPU body that compresses as we drink, this flask makes mid-run hydration intuitive. The 42mm opening is filter compatible for backcountry missions, and the durable construction withstands long-term wear and rugged conditions. Whether we’re chasing PRs or traversing alpine trails, this flask flows with us every step."
