Flame and heat resistance: The primary function is to protect against flames, heat, and hot objects, reducing the risk of severe burns. The fabric is designed to self-extinguish and limit the spread of fire.
Comprehensive protection: A one-piece coverall provides more complete protection than two-piece suits, as it eliminates potential entry points for flames and heat at the waist or hem.
Durable and comfortable: Designed for long hours in tough environments, they are often made with heavy-duty fabrics and a design that allows for freedom of movement.
Functional design: Many coveralls feature a long front zipper for quick and easy use, snap closures on pockets, multiple pockets (including chest and tool pockets), and sometimes adjustable cuffs or waistbands.
