The Sandusa beach towel, the world's first sand-resistant towel, is billed as the beachgoer's answer to troublesome sand assaults. Developed by Australian innovator Baz Brown, the Sandusa is waterproof and sand resistant, and is designed to allow beachgoers some relief from sandy beach gear. According to the Sandusa website, the towel "leaves the beach at the beach."

How does the Sandusa beach towel work?

"Unlike regular beach towels where sand can get trapped in the loopy fibers, the Sandusa's smooth nylon backing allows sand to slip off easily, leaving it dry and sand free," Brown told The Telegraph.

The Sandusa beach towel is made of nylon on the bottom side of the towel and there's an inner waterproof lining.

Nylon is a synthetic polymer, known generically as polyamides, and is found in a number of common consumer products. It is a hybrid material made by bonding diamine and dicarboxylic acid together. Nylon was developed in 1935 in Delaware, and was first used in the production of toothbrushes. Its notable characteristics are its better weathering properties, higher melting point, abrasion resistance, and more compact molecular structure.

"Man's very first synthetic fiber, stronger than steel, fine as a spider's web, more elastic than any of the common natural fibers, splendidly shiny and due to be marketed with the commercial name of nylon, was presented by Dr. Stine, a DuPont vice president, at the New York World Fair on 27 October 1938," the Central Commission for Materials and Techniques, or CCMT, reports.

According to CCMT, nylon was most notably used as material for women's stockings. They became so popular that the inventor, the DuPont company, had to build two additional production plants to meet their demand.

The developers of the Sandusa beach towel are raising money online through the crowd funding campaign site Indiegogo, in which users pledge donations towards innovative projects they like. So far, Sandusa has raised about $9,000 of its $50,000 goal.

What's the one downside of the Sandusa beach towel? You can't flip it over or track sand on it. "We are not magicians," the developers state on FAQs section of the website. "The towelling side is just like a normal towel so if you get sand on that side and stomp all over it, it will remain sandy like a regular towel would."

Here's a video of the Sandusa beach towel, the world's first sand resistant towel, as seen on YouTube:
