## Overview

The HydraPak PocketFlask 500ml is a lightweight, collapsible soft flask designed specifically for runners and outdoor enthusiasts. Its low-profile, tapered shape fits snugly into running belts and vest pockets, while the innovative 28mm locking cap ensures leak-proof hydration on the move. Made from durable TPU and silicone materials, it shrinks as you drink to reduce bulk and bounce. Dishwasher safe and backed by a lifetime warranty, this flask is engineered for comfort, convenience, and long-lasting performance.

## Description

Top to bottom, this is our lowest profile flask. It slips right into the snuggest run belts and leanest vest pockets. The new 28mm locking cap easily opens and closes with a touch of a thumb, preventing leaks and drips while in motion. Made for minimal distraction, the innovative pinch-welded bottom gives it a tapered profile and the low-diameter cap makes it comfortable to carry — no pokes or irritation. Included in the package: - PocketFlask 500ml Flask - 28mm Locking Cap - Bite Valve - Basic Care & Use Instructions Specifications: - Capacity: 500 mL / 17 fl oz - Weight: 32 g / 1.1 oz. - Dimensions: 280 mm x 80 mm / 11 in x 3.1 in - Material: TPU, PP, Silicone, POM

Review: Naked running belts + bottle = winning combo - Like other runners, I have countless water flasks, Camelbak, Hydrapak’s various models (including their easy fill version, hand-held version, etc). This new design is low/thin profile which is perfect for fitting two flasks into a Naked belt. That combo is great for trail running. And also good for road marathons - I’d rather skip the busy aid stations. The lock mechanism is a huge plus. When you put other bottles in a belt, pressure always squeezes the drinking valves causing annoying leaks. That doesn’t happen on this new design. The only compromise is that the bottle opening for refilling is considerable smaller. I have done a road race with these yet. So can’t speak to how fast/slow refilling would be from a typical water jug at a road race.
Review: Leak free - For perfect in my hydration belt and do not leak. Bonus is that they are dishwasher safe!
