The HydraPak 500ml Soft Flask is a lightweight, collapsible hydration solution designed for runners, cyclists, hikers, and endurance athletes who need efficient hydration without bulk. Engineered to fit seamlessly into running vests, hydration belts, and backpacks, this soft flask delivers reliable performance for training sessions, races, and long outdoor adventures.

With a 500ml (0.5 liter) capacity, each HydraPak soft flask provides the ideal balance between hydration volume and minimal weight. As you drink, the flask collapses to reduce sloshing and save space, ensuring a comfortable, bounce-free experience during high-intensity movement. This answers common hydration questions such as how much water a Hydro flask holds—in this case, a precise half-liter designed for portability and speed.

The HydraPak Soft Flask Speed 500ml features a high-flow bite valve and wide-mouth opening for quick refills, including compatibility with ice and powdered hydration mixes. The TM Soft Flask 500 ml variant offers a streamlined profile optimized for easy handling and secure grip, making it ideal for fast-paced runs and races. For extended use or dual-carry setups, the HydraPak 500ml 2 Pack provides added convenience and flexibility.

Constructed from BPA-free, PVC-free, and taste-free materials, HydraPak soft flasks ensure clean-tasting water every time. The durable yet flexible construction resists abrasion and repeated compression, while the leak-proof cap and valve system prevent spills, even under pressure. Cleaning is quick and hassle-free, allowing for better hygiene and long-term use.

Whether you’re tackling trail runs, cycling endurance rides, or mountain hikes, the HydraPak 500ml Soft Flask delivers dependable hydration in a compact, athlete-friendly design. Lightweight, collapsible, and performance-driven, it’s an essential hydration accessory for anyone who values comfort, efficiency, and reliability on the move.
