I purchased this product for my mom as a Christmas gift. She has psoriatic arthritis therefor it can be difficult for her to use her computer at long periods of time but that happens to be her job. The product is made of a high grade of neoprene and is covered in nylon and cotton fabric. It is perfect to use as a compression glove, a thumb splint or even as an arthritis glove. I might even consider purchasing myself one also due to having a smaller version of the same issue. #rankboosterreview
