Doc's is my favorite chamois cream...by a considerable amount. I'm sure I haven't tried them all, but I've tried many. When you first dig into it, seems like maybe it's not going to be all that great, like it's almost too thin, but then it ends up working longer and better than anything else I've used. The only downside...the stuff can be hard to get sometimes. I try to have a back-up on hand because I've run out before and couldn't find any at all, even direct from Doc's.
This is the first real chamois cream I ever tried and don't feel the need to try anything else.
It just works for me, doesn't smell weird, doesn't have some of the major ingredients reputed as bad for your skin (e.g. petrolatum, mineral oil), doesn't stain my cycling clothes.
Even after a 3 to 4 hour super sweaty ride, when I come home and shower, I can feel the chamois cream hasn't been washed away by sweat or degraded into nothingness by the heat and movement.
This chamois creme has a great consistency- not as thickhard as Betwixt and not as thin as Paceline. It also has a pleasant tea tree oil scent without the unpleasant numbing property of some Euro style blends. I probably marginally prefer Assos, but definitely don't find it worth the much higher cost.
I really like this stuff. Great antibacterial properties, feels good and does what it's supposed to. Has just about the same consistency (although slightly less stiff) than the Assos stuff. However, for the same price, you get twice as much.
