The Ultimate Arm Protection against Heat, Flames, Sparks... Waylander Welding Sleeves are made of the highest quality cow skin leather. The sleeves protects clothing and skin from heat, splatter, sparks, thorns, and other features that might hurt the arms while working. To assure comfort on the upper arm, an adjustable elastic keeps the sleeve from falling down. The other side fits well around the wrist, to keep sparks from falling into the sleeve. Other uses for the leather sleeves: grilling, gardening, automotive, metal construction, workshop, carpenter, butcher, and many others.
