While running The Rut Mountain Run, this bottle helped me stay hydrated and avoided crashing out from dehydration.

Ultimate Hydration
Black Diamond’s soft flasks are the hydration setup you want when you’re deep into Colorado’s high country. After knocking out 43 of the state’s 58 14,000‑foot peaks, the difference between “good enough” gear and actually dialed gear becomes painfully obvious — and these flasks land squarely in the latter category. They slide into the Distance 22L’s front pockets like they were engineered for your exact stride. No sloshing, no awkward bounce, no wrestling the flask back into place while you’re gasping up a ridge. The soft‑body design collapses as you drink, which keeps weight tight to your chest and eliminates that annoying pendulum effect you get with hard bottles.
