Salomon created the Sense Hydro S-Lab handheld hydration set that keeps your hands relaxed while you're logging the miles. This unique system designed around the hand with soft vented fabrics perfectly fits your soft flask. Breathable mesh palms keep your hands cool. A thin elastic cord loop keeps the mouth of the flask properly oriented so drinking is as simple as raising your hand to your mouth and taking a sip. Wipe sweat off your brow with the soft terry cloth fabric on back.
