MARS™505 deluxe orange welders have extra-resistant leather, which is achieved by treating leather with extra aluminum and chrome. This added durability extends the life of the glove while increasing protection from open flame and sparks for the wearer. Lined with a 4mm-thick flame-resistant foam lining, they're cut to provide the wider, roomier fit that many welders prefer. Kevlar® sewn throughout for seam integrity, all critical seams are welt-protected. Select sidesplit leather is used throughout.
