Product description

The ultralight Sender Light Harness from Mammut is equipped with just two gear loops and a buckle to adjust the size. It contains only the bare essentials and is therefore aimed primarily at ambitious climbers who want to progress quickly and safely. It's a reliable harness for competition, giving you the best possible support for your performance on the rock.

It’s made of high-molecular polyethylene and polyamide, which makes it particularly strong and durable. High-molecular polyethylene is characterised above all by its high strength. The leg loops are elasticated to keep everything in place and comfortable, although there are no adjustment buckles on the leg loops.

It’s completed by the indicator technology in the tie-in loop, which indicates when the climbing harness needs to be replaced.
