Orange Mud Ultraflask
Best ergonomic hydration solution for long distance trail runners.
This soft flask solves the annoyance of mid-run sloshing by shrinking as you drink, keeping your load stable and quiet. It’s a versatile, temperature-ready solution that prioritizes comfort, though the modular hose setup adds a bit more complexity than a standard, fixed-straw bottle.
