At a mere 12 ounces, the SL 340 Harness is a sport climber's dream as well as Arc'teryx's lightest and most compact yet. Warp Strength Technology offers a surprising amount of support and and balanced weight distribution, while Burly Double Weave fabrication lessens pressure points, enhances moisture management capabilities, and ensures long lasting durability. To keep weight down, Arc'teryx added a single, small, secure, and self locking buckle at the waist. Despite its simplicity, the SL 340 styles safety markers at the belay loop and tie in points for a replacement reminder. There are three gear loops, two at each side and one behind that's perfect for anchors and belay devices.
