I decided I'd cut out the vents in the back of my helmet to get a bit more airflow. I had heard of using window screen repair kits to cover up the vent holes, but the lowes only sold massive sheets for around 15 bucks. Needless to say, I went to find something else. I got an idea in my head and headed to wally world. Now I know everyone here has at least seen bacon fried before. . . you remember that screen you put over the pot to keep from getting jacked by the hot grease? Aaaah yes, and for only 5 bucks I found my new vent covers. They form fit perfectly, kept shape, and stuck with a little bit of hot glue. Pics attached. Thought I'd share. Hope everyone had a good thanksgiving.
