Pocketflask 500ml Water Bottle

What Our Gearhead® Experts Are Saying:

"I stash the PocketFlask in my race belt for long trail runs—it’s so low profile that I forget it’s there. The locking cap gives me peace of mind, and it compresses down as I go. Zero bounce, no leaks—just perfect."

When we’re logging miles on the trail or chasing PRs on the road, the last thing we want is a bulky flask bouncing around or leaking mid-stride. That’s why we reach for the PocketFlask 500ml Water Bottle. Built for minimal distractions and maximum flow, this soft flask fits snugly in even the most compact belts and vest pockets, staying flat against our backs and secure in our kits.

HydraPak designed it with a pinch-welded bottom for a tapered shape and topped it with a low-profile locking cap that opens with a flick of the thumb and stays sealed when we’re on the move. As we drink, the flexible body compresses to cut down on slosh and streamline carry, and when the run’s done, it packs down small and rinses out easily. For our fast-moving days, this flask keeps hydration light, simple, and steady.
