Vented helmets beware

(Avid Cyclist) January 26, 2012

Those helmets with the giant vents with which to rustle your hair are awesome in the summer. However, when it gets below 50degF, I nab this thing in a heartbeat and have relied on it for years. It doesn't feel bulky under the lid (although you may need to increase the helmet tightness band size a bit), cuts out most of the wind, keeps the tips of the ears nice and toasty and is not itchy in the slightest. I do sweat under it if I wear it when it's too warm, but the wool has that nice side effect in that no one else will ever know.
