At Spanish brand Buff, almost all products are one size. For example, the neck warmers, which we often call a "Buff," are available in one size, except for children's models. Buff does use two sizes for its caps. You can find out which one you need in the size chart below.
It's best to measure your head with a tape measure around the thickest point. Don't hold it too tight.
