These are great. They do the job of protecting your tennis racquet grip from rain especially when you carry your racquets in a backpack. They are very Fashionable and I highly recommend them
I had no idea grip covers were a thing, but I must say I really like them. They keep my grips dry on rainy days and it's a far better option than the strange attached cover for one racket (I always carry two) that I had on my Babolat bag.
