Protects against cuts, heat, and fire. Five times stronger than steel on an equal weight basis, Tuff-Knit KV Gloves are made from 100% Dupont™ Kevlar brand fiber- the same material as bulletproof vests. Material offers excellent cut resistance, will not support a flame and can withstand temperatures up to 900 degrees Fahrenheit without breaking down. Designed to last 3-6 times longer than cotton, gloves are seamless so they won't tear and are great for handling glass, welding, or steel manufacturing.
