It's a Velo Plush - however, based on a google search that's a grossly generic name, used for many, many seats. I'm gonna have to find more detail to search for when I check out my bike tonight.

I do agree w/ the shorts comments - the lycra is way up my back, and the chamois in the butt is very noticable off the bike - feel like a duck's tail wagging away I'll try my other shorts next ride ~ nothin like constantly digging out a frontal weggie to make cycling fun
