Mammut Sender Harness is a high-performance climbing harness designed for all climbers looking for a comfortable and lightweight harness to tackle their projects at the crag.
Made with laser-cut fabric in the waistbelt and leg loops, the Sender is extremely breathable to prevent annoying excessive sweating even on the hottest days.
Particular technology is also found in the rear buckles of the straps connecting the waistbelt to the leg loops. The Slide-Bloc system ensures optimal load distribution.
There are four gear loops, two rigid front loops and two softer rear loops.
Finally, the connection ring is protected by a plastic sheath that helps prolong its life. If you start to see red threads coming out of the belay loop, don't panic: it's an innovative system that lets you know when it's time to replace your harness!
