Sender Harness

Mammut's Sender series consists of high-performing climbing gear for all styles of ascent, and the Sender Harness is hyperlight and geared for all-around sending. It has that light, breathable, free-moving design that sport climbers love to fall into when they're projecting, and it's extremely packable for mountaineers and ice climbers. Mammut added four attachments for ice screws, and there are two rigid gear loops and two webbing gear loops for cams and quickdraws, and Mammut added a haul loop and chalk bag attachment for a full arsenal of climbing gear for whatever route you want to send.

Very comfy, prefer the nonadjustable leg loops to the adjustable ones. Wear indicators are a good idea, just a good sport climbing harness.

Sender sends it

As expected for the Sender line this is a super lite harness. And as expected from Mammut the quality is top notch

Great harness

Amazing harness for all around climbing. I used it for ice, sport and trad and I've always been satisfied. Comfortable and lightweight, a good harness.

Super Sport Harness

A super harness that is lightweight, with everything you need and none of the frills you don't. I've used it mainly sport climbing and it easily fits all of my draws on the gear loops. The single adjustable belt loop and elastic on the leg loops make the harness easy to put on/take off, and make for a comfortable experience. The provided storage bag is an awesome added bonus and the bright orange colour makes you easy to spot for all those cool climbing pics!

Works exactly as expected

Fantastic harness which holds to my hips really well. Used on several outdoor climbs and in the climbing gym on a weekly basis. Have zero faults with it so far. Took me some time to get used to the elastic but now that I am familiar with it compared to my old webbing only harness I really like it.

Harness is super light and very comfortable. Previous harness was the 4 slide from Mammut, I didn't realize how bulky it was until I upgraded to this one. The chalk bag attachment is a little funky, if you use a biner to attach your chalk bag to the back of the harness, you'll need to find an alternate solution because it'll twist. Either a belt or the Mammut Crag Sender chalk bag work well.

Comfortable harness

This is a great sport climbing harness that has been super comfortable. I've had it for about a year and have spent many hours hanging in this thing. It is really comfortable, lightweight, and functional. Love the thick belay loop with the indicator warning feature. My only complaint about this is that the gear loops are a little floppy and don't stay cantilevered off the harness very well for easy access to draws and pro. Other than that, this is a great harness that I highly recommend.

Every feature you want in a harness!

This harness is my everyday favorite. Love the fit and the way the buckle slides tight with no hassle. The gear loops are great and look like they'll last forever. The legs are comfortable and flexible. All around great harness for sport climbing.

Super comfortable and high performance

This is the best and most comfortable harness I have ever owned. I especially love the attention to details such as the subtle shape in the gear loops to push the quickdraws forward. Also the wear indicator in the belay loop is nice. Its given me lots of soft catches and I will definitely buy again.
