Found the idea of using a sheepskin car wash mitt from
Sumo on the COG forum. The mitt I bought was $6.97 CDN at Walmart.
I removed the cuff, opened the seams on one side and the top and
sewed the ends of the remaining side seam to reinforce. This yields a bum-shaped seat pad about 9" x 13".
If you're buying a mitt, be sure to look inside and choose one made of 2 pieces, not a number of little pieces sewn together.
I've tried the pad on a few longer rides, it makes things more comfortable and varied in dry weather,
not much good in the rain.
Bought a beaded seat pad intended for car use from Canadian Tire, $9.99 CDN.
Disassembled and reassembled into 3 seat pads for the post-'93 Concours seat, about 13" x 13". Black elastic and
metal hooks attach under the seat to the upholstery lip.
Great on warm days, allows air flow. Hope for good drainage in the rain, too.
