Sweat-Wicking Motorcycle Skull Cap with Adjustable Rear Ties

Why a low-bulk, breathable layer matters under a helmet

NIOSH explains that sweat evaporation is one of the body's cooling mechanisms and that thicker or less-permeable clothing can hamper heat exchange. This thin skull cap is designed to manage sweat at the helmet liner while keeping added bulk low. Read the NIOSH guidance. This is general heat-stress science, not proof of a specific temperature drop, and the cap does not replace hydration, rest or other heat-safety practices.

Keep sweat off the helmet liner

The stretch fabric sits close to the head and helps absorb and move perspiration during commuting, touring and other helmeted rides. Rear ties let you adjust the fit without a thick buckle under the helmet.

Fit and care

Tie it snugly without creating pressure points, then check helmet fit before riding. Hand-wash or use a gentle cycle in cool water and air-dry. Stop using it if it changes the helmet's secure fit.
