I have the Goode Rider ones (both full-seat and knee patch), the Equine Couture, and the FITS Beka. Hands down, I prefer the FITS Beka, because they’re flattering to a chunky body like mine. In fact, if I could replace all my breeches with the Beka ones, I would, but $$$$… If you like the jean feel (meaning soft, washed denim), you can’t go wrong with Goode Rider. They look like regular skinny jeans, really flattering in my Dubarry knockoffs when I run around town, and they wash and wear like jeans (unlike the Bekas, which are made of some different sort of material). They are a mid-rise, and have a wide waistband, which is also flattering. I have two pairs of full-seat Goode Riders, both purchased on sale, and their original knee patch.
I hate the Equine Couture ones. They’re ugly, slippery, and the waist is huge and I have to wear a belt to keep them up, and I’m pretty rectangular in shape (not a curvy, little-waisted hourglass). I rarely wear them and have been considering donating them to the local equine rescue consignment shop. Don’t waste your money.
