I do wear these pretty regularly, and now that I've got a good bike fit and comfortable saddle they work pretty well. The chamois is definitely very thin, which can be harsh but is nice in terms of not getting bunchy or soggy with sweat - really depends on how much cushion you need. The material is pretty nice - I actually find it fairly stretchy, and haven't had problems with the crotch being too tight, maybe mine are just broken in. Not a fan of the upper material - I have to wear a base layer under these even for short rides, just too itchy otherwise. And the combination of them being cut a little short and having pretty poor grippers means they tend to ride up. I'm 6', 160, 32 waist, and the large fits ok, although maybe a bit short.
