Osprey Hydraulics 500ml Soft Flask
Osprey's Hydraulics 500mL Soft Flask is built for runners who need hydration without the bounce. A removable WingStay stabiliser holds its shape and keeps the flask sitting still in a vestpack pocket, even once it's empty. The wide 42mm opening makes loading ice or mixing in electrolytes easy, and the tapered shape slides into pockets without a fight. A high-flow, self-sealing bite valve and easy-grip twist cap simplify drinking on the move, while durable TPU construction with RF-welded seams keeps it leak-free over repeated use. Compatible with the UltraFlask Filter Cap, sold separately, for on-the-go filtration.
