there are many threads about apparel fabrics and I strongly think that synthetic material is much better than cotton for apparels. I have not seen any threads about socks and wristbands. nowadays synthetic fabrics are much better than 10 years ago. there are many fabrics are softer than cottons. I prefer Nike PE wristbands which has nylon and spandex material (because of softness). I feel that cotton fabrics are slightly rough but not really bothers me though. which one do you prefer and why?
