Sonic Harness

Huge Step Up

The sonic is a gigantic leap in comfort and quality over the mass-market gym harness I’ve been using for several years. In particular, the waist belt’s width and padding are just so much more comfortable both when on the wall or belaying. And the materials feel much more durable and premium, with negligible additional weight. I’m also delighted to be able to support a handmade product from my home state!

I absolutely love it! It is quite an upgrade from my old BD Momentum. Very well made, comfortable to hang in, and was able to carry a full trad rack with room to spare. I liked that I could get it with an extra gear loop as well.

Best harness ever!

I've been using MM harnesses for 10 years and I've loved them all. However, my waist and leg sizes don't go well together. I need a med waist belt and small leg loops (skinny leg syndrome). I reached out to the folks at MM to see if they could custom make me a harness and they DID! Only $10 more. I've had a few Sonic harnesses, which all work great, but my new custom Sonic harness is even more great and comfortable! Thanks MM!
