As a mountain biker and triathlete, I get very sweaty and wanted to protect my seats. Neoprene covers are expensive and look like crap IMHO. So I got a few black bath towels and some eyelets and some elastic compression cords and I came up with a temporary seat cover.
All round nice guy
Just picked up a set of elastic cords from the dollar store. Certainly wouldnt use them for anything real, but I feel comfortable in their ability to hold a towel up after kayaking or being caught in the rain.
