The Hydrapak Pocketflask 500ml is a compact, ultra-durable hydration flask designed specifically for runners and outdoor enthusiasts.

This flask is engineered to be the lowest profile option available, making it perfect for snug running belts and lean vest pockets. Its innovative design features a 28mm locking cap that easily opens and closes with a touch of the thumb, ensuring leak-free transport.
