Its double-knit construction makes it highly effective at trapping warm air, while the long neck means the wearer won't experience any unwanted draughts. A one-size-fits all, open-face thermal work balaclava from one of the world's leading garment insulation innovators. Ideal for freezer/chiller work, as well as for work and recreation in outdoor settings, particularly during the winter months.
