How do sand free beach towels work?

Sand-free beach towels are designed to shake off sand easily, making them more convenient to use at the beach. They are made with special fibers that when matched to the correct microfiber suede weave are designed to repel sand. My experience with my Newlyfe (newlyfe.com.au) sand free beach towel is that it is very good at repelling sand and for quickly drying too. They are by their nature also very compact and tend to not smell due to their quick drying characteristics.
