Unless your head swells about 1/2" all the way around when it warms up, I don't see how this is an all-weather helmet. When you remove the winter lining (which is great, btw, super comfy), the helmet just flops around on your head, suddenly way too big. Is there a snap-in summer foam gizmo somewhere? Not that I can find and I've really, really tried. If you know, please, please let me know. Otherwise, what you have here is an unadjustable cold-weather helmet.
