This is Aero Tech Designs’ Merino Wool Balaclava in black, knit from a 48% merino blend with active-heating construction — the dark interior absorbs warmth and insulates the full face and head.
It works under bike and ski helmets, over the face on sub-freezing commutes, and tucked into jacket collars on cold outdoor shifts — the long neck stays put under layers, and one unisex size covers most adults.
Aero Tech Designs has designed and sewn cycling apparel at its factory in Coraopolis, Pennsylvania, outside Pittsburgh, since the 1980s, with one of the widest size ranges in cycling.
