They look weird but are supposed to be very comfy.
Has anyone used one? What are they like?

I borrowed one to do the C2C route, a few years back and found it very comfy.

I had to force myself to sit further back that I did with my other saddle, in order to be sat on the raised pads, but got used to it pretty quickly.

Since then I’ve adjusted my position on my ‘normal’ saddles, and found them more comfortable too.

I seem to remember them having a ‘try it or return it’ policy, too.
