Infinity saddle

Yes... I've been using them for years. It's without doubt my favourite saddle ever.
I have one on my 29er, and have done long multi day rides on that, and I have one on my work bike which I ride 5 days a week.
My first one was the original bare plastic version. Second one has the leather cover just down the middle edges.
The only criticism with mine is that they shred the fuck out of the arse of my trousers on my work bike.
The newer fully covered version in your picture would stop that, but I can't afford another one at the moment... They're not cheap.
I haven't had ANY saddle sores or chafing since swapping to the Infinity.
I also never wear padded shorts anymore either.
They feel a little strange at first, but once you get used to the feeling of sitting 'in' it, rather than 'on' it, they're awesome.
