The ArcTeryx SL-340 is the most compact, super light (SL) harness in the current range. Streamlined, sleek and nimble, the SL-340 has been specifically developed for sport climbing and hard 'head point' style trad ascents. It has been designed with a unisex fit to suit both women and men.

The SL-340 delivers security, agility and freedom of movement when you are performing at your limit. Hardwearing Burly Double Weave absorbs little to no moisture, dries quickly and is soft against skin. The waistbelt construction is updated with a softer edge that creates less pressure and improves overall comfort. The disciplined design means features are stripped to the essential; at 340g (12 oz), this is THE lightest and most compact Arc'teryx harness.

Warp Strength Technology
WST™ differs from traditional harness construction in that the load is evenly distributed across the entire width of the harness structure rather than loading a single, narrow strip of webbing in the centre or running edge binding, both of which tend to concentrate the pressure of the harness making them less comfortable. Warp Strength Technology™ cradles the body and the load is universally dispersed from edge to edge. This construction method provides a high degree of support and this new generation of harnesses are more comfortable over time and usage than ever before.

The rocknrun service was excellent.

The rocknrun service was excellent. The harness though is not as brilliant as expected for a top price harness. The size is ridiculous, I use to wear M or S, I took the measurements and read the sizing chart and ordered an S, and the harness is big for me. I'm a male 187 cm and 70 kg, stunning to know I wear XS. I also bought that harness because I have back pain and I've been recommended because the thick back support, but my feeling is worse than with my petzl corax. Nevertheless is reaaally light, and comfortable if you get the proper size.
