Arc'teryxSL-340 Harness

Light, compact, and reliable.

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.

Arc'teryx does it again!

  • Familiarity: I've used it once or twice and have initial impressions

Sleek, simple, functional, durable, lightweight, and amazing... did i mention amazing! I never imagined a harness this thin and lightweight could be this comfortable. I am not a gram counter when it comes to sport climbing gear usually but I appreciate how lightweight this is! If you are looking for a comfortable Ultraligh amazingly well built sport climbing harness look no further. That being said this harness is NOT a trad or multi pitch harness as it only has 2 gear loops to help save on overall weight.

To clear up any confusion

    So I know Arc'teryx harnesses can sometimes not make sense and a little confusing on which one is best for you, here is a break down video from Arc'teryx to clear everything up:

    This harness works great

    Woah mama.

    • Familiarity: I've put it through the wringer

    Seriously. What the hell? This is like being help up by a divine force while on the wall. There are no pressure points and I honestly don't even notice i'm wearing it. The technology that distributes the force throughout the harness instead of into focused ropes is the technology to thank. I know it looks pricy, but it's worth it in my opinion.

    Loving the reviews, thank you!

    Lightweight safety
