Bringing year-round functionality, the Black Diamond Momentum 3S harness handles everything from mid-week gym sessions to alpine trad climbs. Speed Adjust buckles on the waistbelt and leg loops accommodate changing layers throughout the seasons and help you dial in the perfect fit, while four gear loops hold enough draws and pro for any route on your ticklist. The Momentum 3S is built with Dual Core Construction, which uses two bands of thin webbing and an OpenAir foam insert in the waistbelt for affordable support and breathability without pressure points.
