Black Diamond Ethos Womens Harness

1   |  

The Black Diamond Ethos Womens Harness is the ultimate super comfortable and durable women's specific trad climbing and mountaineering harness. 

Specifically aimed at those who want a tailored, unencumbered fit with maximum breathability, enhanced comfort and a robust construction, the Ethos is based of the men's Chaos and is built for long routes and to withstand serious amounts of abuse. Perfect for everything from cragging in a Lakeland valley to BIG routes in the Alps, this harness would even suit a sport climber wanting something more robust. 

The Ethos packs a comfort orientated, yet low profile, womens specific bullhorn-shaped waistbelt, built using BD's Kinetic Core Construction: this uses a thin layer of Vectran fibers in place of traditional webbing to evenly distribute weight across the waist and legs. As well as the use of a modern hot-forged speed adjust (or ziplock) style waist buckle, the harness also comes equipped with four large pressure moulded gear loops, with easily enough room for all your gear. Finally, a 12kN-rated rear haul loop is included to finish off this fabulous piece of gear, and all this at just over 350g (size small).
