Lowering down a big chunk of vertical real estate is just the beginning. When your rappel ends in a frigid pool, you need to know you've got reliable gear. Feel confident in your trusty Edelweiss Canyon Static 9. 6mm Rope. Treated with EverDry, this abrasion-resistant cord won't pick up as much water weight as comparable, untreated models. Unlike many of its peers, the Canyon Static shrinks by a mere 1% in water, and weighs in at just 59 grams per meter.
