比利時帽

Wore this on a windy morning and the flaps actually stay put over my ears, no tugging needed. It's thin enough to fit under my bike helmet without feeling bunched up.

I was skeptical a cap could handle real cold, but this thing blocks wind way better than my old beanie. The flap folds down over the ears on the nastiest mornings, and it still fits fine under my helmet.

Wore it on a windy 40-degree ride and my ears never went numb once, which is more than I can say for my old beanie. It's thin enough to sit under my helmet without bunching up.
