The Momentum 4S harness from Black Diamond is built for both gym days and outdoor climbs. Four Speed Adjust buckles allow precise tuning at the waist and legs, making it easy to adapt to layering and movement for varied conditions.
Two standout comfort features include Dual Core Construction that distributes weight across hips and legs and a soft, breathable lining that reduces pressure points and boosts mobility during long climbs, belays, or rappels.
Pre-threaded buckles offer quick, intuitive adjustments that stay put as you tighten. This makes it practical for gym sessions, crag days, guiding, or group settings where versatility and safety matter.
Equipped with four gear loops and a rear haul loop, the Momentum 4S helps you organize quickdraws, cams, belay devices, or anchor hardware on any route. The layout supports balanced weight and easy access to essential gear.
Constructed from high-strength materials, this harness is designed for repeated use indoors or outdoors. It supports gym climbing, sport routes, trad climbing, and alpine objectives, with resilience across seasons and layering setups.
Who is this for? climbers who value a highly adjustable fit, comfort over long sessions, and practical gear organization. The design invites you to imagine better ways to approach climbs without guaranteeing outcomes.
