HydraPak Ultraflask Speed
Best lightweight hydration solution for long distance trail runners.
This flask solves the mid-run annoyance of sloshing and bouncing by collapsing as you drink, keeping your vest stable and quiet. While the soft material requires a bit more care than a rigid bottle, the ability to filter water on the fly makes it an essential upgrade for long-distance trail days.
