  • Product Type: Unisex lightweight climbing harness
  • Material: Warp Strength Technology
  • Weight: 275g
  • Precision-engineered for sport climbing
  • Next evolution in Warp Strength Technology balances support, comfort, and durability for repeat sessions

Featuring the next evolution in Warp Strength Technology, the Lithos SL strikes the perfect balance of support, comfort, and durability, meeting the demands of the most committed sport climbers, session after session. Plus, with a revolutionary sizing system, you can customize your fit like never before, dialing in the perfect waist-to-leg-loop ratio for all-day comfort.

Harness features

  • Belay loop
  • The next evolution of Warp Strength Technology integrates structural fabric across the back panel, simplifying construction while dramatically enhancing support and maintaining the harness’s incredibly thin 2mm waistbelt
  • Two snap-fit moulded gear loops are strategically placed for effortless clipping and can hold a full rack of quickdraws while keeping the harness streamlined and minimalist—perfect for projecting and redpoint attempts
  • The new forged buckle design improves the cinching action for a secure fit while making it easier to take the harness on and off
  • Both leg loops are a single, continuous piece of webbing, which eliminates high-wear stitching in critical areas, increasing durability and drastically improving mobility for unrestricted movement on the wall
  • The elastic rear rise is easy to unclip one-handed, even while wearing the harness, and it’s easily replaceable, extending the harness’s lifespan
