Trail Flask 350

Pure Water. Any Trail.

Never worry about where your next drink will come from.

The HydraTrail Pure Flow Flask 350 gives runners and adventurers the freedom to access clean, filtered water whenever they need it. Designed for trail runners, ultramarathon athletes, and explorers, the advanced PureFlow™ filtration system allows you to safely refill from natural water sources so you can travel lighter and go further.

Instead of carrying heavy water supplies, simply refill along the way and keep moving. Whether you're running deep into the mountains, training on rainforest trails, or pushing through long urban runs with a hydration vest, HydraTrail ensures clean water is always within reach.

Lightweight, flexible, and built for performance, the PureFlow™ Filter Flask compresses as you drink to reduce sloshing and fits comfortably in most running vests and hydration packs.

Run with confidence knowing that clean water is always available when you need it.
