The Arc'Teryx A300a Climbing Harness is a super light and compact mountaineering and ski touring harness that doesn't sacrifice comfort for performance. The Warp design of the A300a allows for the waist belt and leg loops to spread the climber's weight over a larger surface area. Combine this with a belay loop that has orange strands to indicate when your harness is warn out, two molded reversible/removable gear loops and self locking buckles, and you have one of the best setups around. Stripped down to the alpine essentials, the A300a Climbing Harness is one of the lightest, compact, and comfortable fully-adjustable alpine harnesses on the market.
