Orange Mud Ultraflask
Best ergonomic hydration solution for long distance trail runners.
This flask solves the annoyance of sloshing by shrinking as you drink, keeping your center of gravity stable during intense movement. While the removable hose adds a layer of complexity to your setup, the trade-off is a versatile, temperature-resilient system that adapts to any pack or pocket.
