The main difference between the Quick-Dry towel and the Beach towel, is the type of fabric that is used. The Quick-Dry towel is a microfiber material that is made from 100% post-consumer waste, primarily plastic water bottles. They are compact and ultra lightweight which makes them dry out incredibly fast. The Beach towel is made with a super soft and absorbent fabric that is entirely made out of cotton. It's thicker, more plush and has that classic terry cloth feel.
