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:

    I bought this as a gift for my friend, he absolutely loves it. Out of curiosity I had to try it on it fits perfect and is so so so comfortable haven't worn it on the wall, however that might change soon looking to buy one for myself soon!

    Pull the trigger!

    You Should Buy One

    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
