The Stormlock Banff Springs Cap from Jack Wolfskin is the winterised version of the classic baseball cap. It has a soft, lambs wool-like fleece lining and a microfibre thermal lining. The cap is also windproof, so icy cold winds don't stand a chance. And if you get a bit too warm when you're out chopping wood, the breathability performance ensures a pleasant wear climate. Or you can just fold up the ear flaps and neck protector to cool off a little.
