I had someone on a post ask me to post pictures of of the carrier from a forum that I can not find again.
They were inquiring about my post stating I have this available for sale. $50 pl;us $30 shipping.
I wondered about the ones on ebay for 12 -15 $. Read a review that said they soak up water and your butt gets soaked. Do not have a Wind Rider yet, but the apparently use material that lets the water flow out?
