1 review   |  

The Mammut Sender Fast Adjust is the lightest Mammut climbing harness with adjustable Fast Adjust leg loops.

Highly breathable and extremely lightweight harness specially for performance sports climbing. The laser-cut fabric offers exceptional breathability and robustness, while split webbing technology ensures optimum weight distribution. The Fast Adjust buckles on the leg loops make it possible to adjust the width of the leg loops in seconds without worrying about an additional belt strap.

      Really happy with it.

      This harness was bought to replace one I had gotten too small for. It’s bright, it’s light and it’s comfortable. It’s a really good harness for sport climbing. But has also been good for trad too. The fifth gear loop is very useful. And it has extra small loops around it as well for things like a brush or a chalk bag. Would highly recommend this harness. Rock + Run’s stellar service makes them a pleasure to deal with always.
