What are karate suits made of?

Answer 1

The karate outfit is called a gi or dogi. It is usually made of heavy cotton. Many of the lighter weight ones are now a blend of cotton and polyester, particularly for the kids. Senior practitioners like the heavier weight ones as they stand up to the pulling and tugging of the throw better. And contrary to what you would think, a heavy gi is cooler to wear than a lightweight one. The weight is measured in ounces, indicating how much the fabric weights. The lightest I've seen is 5 oz and I have a 14 ounce heavy weight.

Answer 2

They are made from all sorts of cloth, the least expensive ones are made of cotton. The highest quality ones are made of silk over a cotton core.
