I have a pair of Shebeests with the "SheLastic" chamois. I like them a lot and find the chamois to be just right, neither too thick (diaper butt ) or too thin (ouch). The leg elastic is snug without feeling too tight.

I also have pairs of 2007 Terry knickers and tights that seem to have the same chamois.

Sugoi Evolutions with the Ricaro2 chamois are also a comfy fit for me.

PI is my least favorite brand. I know a lot of women like the Sugar Short, but I only wear them if nothing else is clean.
