Versatile and Compact Hydration for Any Adventure

The HydraPak PocketFlask 500ml is a highly portable, flexible hydration solution designed to fit where traditional hard bottles cannot. Ideal for stashing in a jacket pocket, a running belt, or the side mesh of a daypack, this soft flask collapses as you drink, significantly reducing water slosh and saving space as it empties. Its minimalist design makes it an essential tool for those who need quick access to water or electrolyte drinks without the bulk of a standard bottle.

Despite its lightweight construction, the PocketFlask is built for durability and ease of use. It features a high-flow bite valve that provides effortless hydration on the move and seals automatically to prevent annoying leaks. The 28mm cap is compatible with many water filtration systems, making it a versatile choice for backcountry travel. When empty, the flask can be rolled up or flattened, disappearing into your pocket until your next refill.

Key Features:

• Collapsible Body: The soft material conforms to your body and shrinks as you drink to minimize movement and maximize pack efficiency.
• High-Flow Bite Valve: Delivers water quickly with a gentle squeeze and features a leak-proof shut-off for secure transport.
• Stowable Design: Rolls up or folds flat when empty, making it incredibly easy to carry as a backup or primary hydration source.
• Filter Compatibility: The standard 28mm threaded top is compatible with various backcountry water filters for safe drinking anywhere.
• Rugged TPU Construction: Made from abrasion-resistant TPU with RF-welded seams for maximum durability and flexibility.
• BPA & PVC Free: Constructed from safe, food-grade materials that ensure your water stays taste-free and healthy.
• Easy to Clean: Top-rack dishwasher safe, allowing for simple and thorough maintenance between adventures.
