Soren, I got the large for me and the #2 size passenger pad. Black in color. They attach with an elastic strap that goes under the seat, and seems to remain in place nicely.
The nice thing about the strap is that it has those quick disconnect buckles on both sides so you can remove it in a snap if you don't want to leave it on the bike.
By the way, alaskaleather delivered it to me instantly. Very prompt turnaround.
The wife gave it a quick try the other night. Look, anytime I can spend $100 on the bike and it makes the wife happy, it's got to be good. lol
I'll try to post pictures soon.
