The Cavalier ones are good
I had one that had silicone (where the saddle is placed) and cotton in the outter part. I really didn’t like it at all, even though it had silicone it keep moving and was very difficult to fit. I prefer the ones that only have cotton in the sides. Those are the ones I am using now.
Ecogold will not slip at all!!
kavallerie gel half pad is amazing! It's gel so it keeps everything in place, its shock absorbing and has so many more features. Heres a link to buy it: https://mykavallerie.com/ Hope this helped!
Ecogold are non slip or acavallo gel
