Almost certainly not. Hoods for helmets generally advertise that feature specifically because they're HUGE, and this one doesn't.

Hi bri,
Actually, yes, the hood does accomodate a bike helmet. I have a size Lg Vapor Hoody, and a medium size road style bike helmet, and could pull the hood over the helmet. Hope this helps you.

Angus is making a claim based on how this item is advertised...Jeff responded with actual testing. Call Backcountry for some help first...then decide.
