Rayon is a natural fiber made out of cellulose and is very close to cotton. Rayon sarongs are very popular because the fabric is soft,smooth,and comfortable. Like cotton,rayon sarongs are also more casual in appearance often having fringe. Many rayon sarongs are hand made with designs that are painted or batik but also come solid. Rayon is durable but can shrink or crinkle with washing making most rayon sarongs dry clean only.
A large portion of sarongs are made out of polyester because of it's lightweight, flowing qualities and wrinkle resistance. For some, polyester can have a negative image but sarongs made of this fabric are quite beautiful and glamorous. Polyester takes print and color well making even the most intricate printed sarongs look fabulous. Polyester is also quick drying; it only take a few minutes for your sarong to dry once wet and there are never concerns about your sarong "bleeding" into your swimsuit. Polyester sarongs are machine/hand washable. Polyester sarongs come in wide range of colors and styles making this a great choice.
Cotton is also another popular fabric for sarongs. Cotton sarongs tend to be more casual and come in both a traditional rectangular style and the more modern sarong with the built in tie. This fabric can take on many looks, it can can be smooth or crinkled (gauze). Cotton sarongs come in solid colors or can be printed. Key benefits of a cotton sarong are comfort, durability, quick drying, and also light weight. A cotton is machine/hand washable but does not offer as much wrinkle resistance as some of the other fabrics.
