What Our Gearhead(R) Experts Are Saying: "I've worn a bunch of facemasks over the years, but the Terryclava nails it-super breathable, never clammy, and thin enough to fit under a helmet without bulk. It's my go-to for cold days on the mountain." The Airblaster Terryclava keeps our face covered and cozy without overheating or feeling soggy halfway through the day. It's the OG single-layer facemask that ditched bulky double knits for breathable, quick-drying performance-and yeah, we're never going back. Airblaster's acrylic knit stretches comfortably over our head and sits soft against the skin, making it an easy favorite for deep resort laps and cold-weather commutes. It slips seamlessly under helmets and hoods, and the retro Airpill logo gives it that signature Airblaster flavor we know and love.
