Trail Runner™ Soft Flask

Water & Hydration

Color

Selected: Clear Lake

We teamed up with Hydrapak® to bring the performance of their iconic soft hydration flasks to you and your dog’s next adventure. They’re made of a pliable, lightweight material for a hydration solution that’s easy carrying - whether that’s in your running belt or your running vest (or your dog’s). Just twist the valve and squeeze the bottle to dispense water for a trailside straight-from-the-spout-sip or a dog bowl refill.

Compatibility: Trail Runner™ Belt (360 ml); Trail Runner™ Running Vest (360 ml for size XS; 500 ml for size S - L/XL)

Final sale. Not available for return.

    Incredibly useful for on the go!

    We love filling these up with water and some ice to throw into our day pack for our dog. Two of these packs hold enough water for a long hike. They are lightweight and completely leak-proof!

    Perfect

    My dogs drink from bottles so this is perfect. Folds down to nothing when empty.

    Great idea

    We haven’t used them very much so I can’t rate durability but we can certainly hike a lot farther with the additional water in our Switchbak harness.
