Combining lightness, suppleness and support, the Arcteryx R300 climbing harness is well suited for alpine climbing and trad climbing. Warp StrengthR Technology WST allows the harness to be shaped and contoured to the climbers body for excellent support and comfort. WST eliminates the need for excessive padding by uniformly spreading the load across the entire harness. Self-locking 7075 T6 aluminum buckle at the waist provides an extra margin of safety by allowing adjustments while maintaining the proper double-back configuration. 4 webbing loops sewn directly to harness are sheathed by injection-molded polyurethane gear loops. Shaped for forward racking, polyurethane gear loops are reversible and removable loops remain flexible in extreme cold. Core of tie-in points and belay loop feature Wear Safety Markers when the sheath is worn, bright orange will show to indicate that abrasion to structural webbing may occur. Stretchy leg loops offer a precise fit without restricting range of motion. Exterior stretch-woven fabric is lightweight and highly abrasion resistant spacermesh on inner face is soft and breathable. Non-structural haul loop lets you trail a second rope. The Arcteryx R300 climbing harness comes with a stretchy mesh storage bag.
