The PocketFlask 500 ml is Hydrapack lowest-profile flask yet, designed to fit into the snuggest running belts and leanest vest pockets. With a sleek top-to-bottom profile, it stays comfortable and unobtrusive while you move, eliminating pokes and irritation even on longer runs.
The new 28 mm locking cap opens and closes easily with a simple thumb action, preventing leaks and drips while on the move. An innovative pinch-welded base creates a tapered shape for a secure, low-profile fit, while the flexible design shrinks as you drink to minimise water movement. Made from ultra-durable, abrasion-resistant TPU with RF-welded seams, the PocketFlask is built to last. A self-sealing bite valve delivers smooth, drip-free sips, keeping hydration simple, fast, and distraction-free.
