We have these on some of our bikes, heaps of customers have tried them and without exception all have bought one or more!
What makes them so good, they are comfortable, tough, waterproof (no spongy wet bum!) and look a bit different. There is no cover to rip, you can scuff them but it wont rip or tear. The design makes you "sit in" they soften up initially but then wont change more form there. What you buy is the shape it will be in many years time, and with a 10 year warranty it should last a while.
Two basic styles available, C17 & 15 both in Ladies "S" fit and Carved(centre slot). Colours are Natural, Black and Slate, the colours will fade in the light however.
If you ride your bike a heap, do big miles then these are well worth a look.
