GearTop's Skull Cap Helmet Liner is the hat you forget you're wearing — until you realize your head is still dry, comfortable, and perfectly in place. Built for runners, cyclists, skiers, and anyone who wears a helmet, this moisture-wicking liner keeps sweat out of your eyes and your focus on the road, trail, or slope.

FEATURES

• Quick-drying moisture-wicking fabric pulls sweat away from your skin
• Breathable construction reduces heat buildup during high-output activity
• Snug but non-restrictive fit keeps hair in place without a tight squeeze
• Sweat-absorbent liner fits under helmets cleanly — no bunching, no pressure points
• One-size-fits-most construction works for a wide range of head sizes
• Thin profile fits under bike helmets, ski helmets, and hard hats without adding bulk
• Machine washable and quick-drying for easy daily use

TWO WAYS TO WEAR IT

As a standalone running beanie: On cool-weather runs, the skull cap keeps your head warm without overheating. The open-face design keeps your vision clear and ears covered. It's thin enough to not feel bulky at tempo pace but warm enough to cut wind chill.

As a helmet liner: Cyclists, skiers, snowboarders, and construction workers know the problem — helmets trap sweat and get uncomfortable fast. The GearTop skull cap creates a wicking barrier between your head and the helmet padding, absorbing sweat before it runs into your face and extending the time between helmet washes.

TEMPERATURE RANGE

Best suited for 0°C to 15°C (32°F to 59°F) conditions as a standalone hat, or as a liner layer in colder temperatures. For sub-zero conditions, layer it under a warmer beanie or inside a full winter helmet.

CARE INSTRUCTIONS

Machine wash cold, gentle cycle. Tumble dry low or air dry. Do not iron or dry clean.
