The Bicycle seat cover from KTS is as described on the product description page.
https://www.amazon.com/gp/product/B01LY5TRDF. This padded gel seat has a drawstring for getting a tight fit and also has non slip grips on the inside of the fabric. I get saddle sore. I have creams, padded undergarments and padded shorts to help with the soreness and I think this seat cushion is going to help too. It seems to have padding in all the right spots without having too much out the sides.
I have stored my e-bike for the winter and have another one shipping out to me for Christmas. I used one of my seats that I had in storage and replaced because it was not comfortable. This seat cover will be great come Spring when I can get back out and get some exercise and vitamin D.
