Stay regulated and protected in changing conditions with the Purple Mountain Observatory Polartec Alpha balaclava in black. This technical balaclava wraps over your head and neck to shelter you from cold, wind and moisture while adjusting insulation as you move. The Polartec Alpha fleece construction helps trap warmth when you’re still and vent heat when you’re active, making it ideal for high-intensity outdoor use.
