Developed in conjunction with a hang glider pilot looking for the perfect baselayer. The unique fabric structure of Cellular traps maximum insulating air next to the skin. At the same time it enhances moisture dispersal so skin stays dry, making it ideal for extremes of both heat and cold. Also perfect for snow sports, cycling, hiking. Sunglasses slots, off-centre front zip, thumb loops and flat seams. The all-in-one hood and top eliminates the chilling neck gap that can occur if a top and hat are worn separately.
