100% Inherent ARC FR Protection The FR protection is woven into the fabric meaning it is permanent. No matter how many times the garment is worn or washed, the protection level always remains. This results in peace of mind knowing all STRATA garments will keep engineers safe for the life of the garment and it saves you money reducing the cost per use by not having to keep replacing garments after their chemical protection is washed out. Easi Arm Gusset Technology The added underarm panel has been fitted and developed to give greater freedom of movement through the sleeve and shoulder for working overhead and on the ground without exposing any skin. Tight Knitted Structure The fabric has been tightly weaved together ensuring the inside of the jacket will keep you warm while the outside insulates. The article itself does not pill, it has been made in a way so that it does not collect dust, fluff or any bobbles. Pockets 2 X Concealed Zipped Pockets
