The Singing Rock Onyx Harness is a high-end rock climbing harness providing maximum comfort, low weight and superb freedom of movement.

This excellent harness offers a simple design encompassed within a deceptively high performance laminate constriction. The waist belt and leg loops are built with a combination of robust yet breathable PES micro mesh and a durably light diamond weave Nylon laminated to an EVA padding. The PES micro mesh is positioned across all contact points with the body, whilst the Nylon is just where you need it to minimise abrasion. The harness comes with 4 stiffened gear loops, a drop seat and Singing Rock’s patented stainless steel Ziplock buckles, which are both stronger and less likely to wear than their alloy counterparts.

Designed for use on sport or trad routes where movement, lightweight construction and feel are paramount.

  • Flexible leg loops with elastic straps adapt to the user´s legs
  • One patented Rock&Lock ziplock buckle - made of stainless steel to increase strength and corrosion resistance
  • Streamline laminate construction guarantees unlimited movement
  • Leg loops and waist belt feature variable width webbing - this ergonomic construction combines maximum comfort and low weight
  • Padded waist belt and leg loops are made from EVA foam and breathable PES fabric with high abrasion resistance
  • 4 new ergonomic braided gear loops are shaped to facilitate handling and provide extra space
  • BMI Adjustment: allows users at the bottom end of a given size to keep the waist belt overlap neat and comfortable
  • Supplied with a quality mesh storage sack

Brilliant light weight harness that's

Brilliant light weight harness that's really comfortable. Legs are on elastic which means if you have bigger thighs then there is no adjusting room but other than that it fits perfectly.

Great harness for the money - easily pass as £55 harness.

I've now worn this harness

I've now worn this harness on a variety and it works great. Found it to be super comfortable and easy to take on and off. The sizing is perhaps not quite perfect - I have a 31" waist and this seems to the minimum for a Medium size.
