I just wore a balaclava for the first time (this is the first season that I've decided to ride past the beginning of October, so I bought a bunch of stuff to keep me warm), and had quite an unexpected problem. The temple bars of my glasses hold the balaclava open on the sides, acting as wind scoops. Not enough to actually let air in and make me cold, but enough that it gets REALLY LOUD! Riding without glasses is not an option for me, but I'd like to do something about the noise. Also, I'd prefer to wear my glasses on the outside of my helmet straps, but that doesn't seem possible with the balaclava.
I THINK the solution is to cut holes in the balaclava just in front of my ears, and insert the temple bars of the glasses through said holes, but I wanted to see what advice I get here / what others in my situation have done before I permanently alter my balaclava.
