Navy and white striped knit fabric, featuring fluorescent yellow accents. - Color: Navy and white stripes - Material: Knit fabric - Design: Thin stripes and fluorescent yellow accents Thank you for viewing. Both items have been stored at home, and I'm selling them because I don't think I'll be able to use them. Polyester, nylon, polyurethane, or something similar - I'm not sure of the exact composition. The fabric width and length are listed conservatively, so they are actually wider and longer.
