Most of our products are constructed with either our patented noiseless cotton Fabrapel barrier (for light-moderate sweat protection) or with a noiseless, water-proof urethane/vinyl barrier for moderate-heavy sweat protection. Fabrapel is outstanding with water-repellency, odor-repellency and stain-repellency capabilities and feels like regular soft cotton.
If a product is made with Fabrapel then its style number is designated with an F for example 2483F.
