Leather gloves are desirable for a number of reasons. They provide good grip, insulation, and durability. They’re thicker than regular fabric, which offers a higher level of protection. However, leather gloves tend to dry, crack, or shrivel when excessively exposed to high temperatures. They’re not ideal for working with heat because of this reason, though they do offer adequate burn protection when in good condition. Welders commonly use leather gloves, usually with a durable liner to offer extra protection.
