Very Happy

A friend recommended this harness and I couldn't be happier. Lightweight, easy to use and very comfortable.

Ethan Van Win
Awesome harness!

Awesome harness! Fits really well.

Jack O
Comfy and light

Very light and breathable. Fits comfortably, but obviously doesn't have the padding of some heavier harnesses

Great harness

Lightweight & comfortable - far better than the recent Petzl harnesses (especially the Astro, which is crap). Would recommend as a rope access work harness.

Simon Sharples
Comfortable and lightweight

Definitely the most comfortable harness I've worn, doesn't chafe at all. Also very lightweight and a fair price.
Thanks verx!
