Works well under a bike helmet. Protects from wind and rain pretty damn well, the ear flaps stay comfortably in place even in strong headwinds. I've used between -2 and +8c, it's perfect!

This sort of headgear is held in high regard by mushers, ski tourers and anyone who’s ever spent some time in the Nordic fells on a bitterly cold, windy Fall day. The cap gives complete protection for your ears and its peak has a metal wire, allowing for and adjustable shape. And as you’d expect of SealSkinz, the cap is also completely waterproof.
This product used to be called the “Waterproof Extreme Cold Weather Hat”.
