FORESTER professional chainsaw safety chaps are UL listed and meet all OSHA requirements. From the 1200 denier water and oil resistant oxford outer shell with 6"x6" pocket, to the 12-layer chainsaw protection inside, these chaps are built to provide the highest level of protection. SIZING: All chaps fit waist size 28"-44". Short length fits most 5'-5'4", Regular length fits most 5'4"-6', Long length fits most 6'-6'4". Please note: Chainsaw safety chaps are designed to reduce the risk of injury should the chainsaw chain come in contact with the protective chaps.

These chaps are not suitable protection for use with electric chainsaws, due to the high- torque nature of electric motors
