Streamer II 500ml Flask with self-sealing valve for smooth hydration
What Our Gearhead® Experts Are Saying:
“I love the Streamer II 500ml Flask for running and fast-paced adventures. It shrinks as I drink, so it doesn’t slosh around or take up extra space. The self-sealing valve is awesome—I never worry about leaks when I’m moving fast.”
We’re always reaching for the Streamer II 500ml Flask when we need hydration that keeps up with our energy. Designed by HydraPak® and built for everything from running belts to bike rides, this lightweight flask keeps water right at our fingertips. Its soft, flexible body shrinks as we drink, so we’re never distracted by bouncing water bottles.
The self-sealing valve prevents leaks and the wide 42 mm opening makes refilling on the trail a breeze. And like all Deuter gear, it’s BPA-free and made without PFAS, so we can stay focused on the adventure ahead.
