Petzl's High-end climbing and mountaineering harness.
The padding is made of Petzl's WIREFRAME technology. This is made up of dyneema cord/strands covered in a thin layer of foam thereby evenly distributing the user's weight. All this whilst retaining an extremely lightweight and comfortable harness that is easy to move in. It also packs in a small bag the size of your fist.
The gear loops should also accommodate British trad racks, with the option to divide the front loops with a spacer, further utilising the space.
The result is a true all round harness that will be as at home on single pitch sport as it will half way up a big mountain route.
