I have had a Big Skinny wallet for many years and I think it is the best wallet I have ever had. It is so light weight, thin, and has rounded corners so that I cannot feel it is in my pocket most of the time. It is made of a tough nylon type material. After all these years, it shows almost no wear. The material is durable and washable and is easily dried out if it gets wet. I am a fisherman, kayaker, and gardener so it has not had any special treatment. I have quite a few credit cards, membership cards and ID cards and it is surprising that this wallet will hold up to 20 cards! You won’t go wrong with this wallet. Available in brown and black.
