Ella Adamovská climbs in 3B Slight

A few words from Eliška Adamovská:

This is the best harness I’ve ever owned. I think it’s already my sixth in a row and that’s just because I read somewhere you should replace them after each season. Otherwise, I’d probably still be climbing in the first one, it’s untouched. It’s a mystery to me why this harness, despite being so light and despite seeming so fragile, shows no sign of wear and tear. Even a whole year and a million falls later, it still looks good as new.

I use it for competitions, where its weight is the main thing, but also on the rocks where I love its firmness and durability. It has basically everything I expect and need from a harness, so I’ve never really considered using any other.
