In the cool months the Sweatvac helps keep my head warm, and adds a little cushioning between my skin and the helmet. The real benefit is in the warm and hot months, when I can wet the Sweatvac and let the airflow in my helmet bring the temperature of my head down. Cooling my head helps me think more clearly, makes me more alert, and makes me want to ride farther.

Excellent fit and keeps the sweat dried up.

It works great and my helmet stays dry.

Works great and is comfortable.
