When pushing our grade, we cinch on the Black Diamond Zone Harness for reliable performance that's both ultralight and comfortable. The 4-way stretch material is breathable and moisture wicking, keeping us moving freely through the crux and cool as we fight off the pump. Thanks to the contoured, women's specific fit, when we blow off the wall, a hard catch won't feel like we're breaking in half, while the Fusion Comfort Tech construction uses 3 strands of webbing in the waist and legs to prevent pressure points as we hang and suss beta.
