Kitchen Grips mitts are unique, offering unparalleled hand protection and a secure grip, without being thick and bulky. They're made from a soft, pliable, waterproof (and steam-proof) material called FLXaPrene. The comfortable material features a nubbed surface that gives you a no-kidding, confident grip on hot pans and dishes. FLXaPrene is temperature-rated to provide protection from to 500 degrees F to -134 degrees F. The cuffs on Kitchen Grips mitts can be folded down for extra arm protection. In addition, FLXaPrene is both anti-bacterial and anti-microbial, with non-porous surfaces that do not absorb stains. Cleaning is a snap, as the water-repellent, stain-proof fabric washes up perfectly with soap and water, or even goes in the top rack of the dishwasher or in the washing machine. Air dry only.
