Though I've gone through alot of basic woolly offerings I find the wind tends to go straight through them - maybe I have sensitive ears. I've preferred a
Lowe Alpine mountain cap for about 10 years - nothing beats it for keeping your lugs warm in a strong wind.
I hate the restriction of wearing a waterproof jacket hood unless I really have to; the cap is great as your hood becomes unnecessary unless the rain really is pouring down. Seemed expensive when bought maybe, but I can't see that it'll ever wear out. As opposed to footwear where I go through a pair or two every year.
Maybe we will test the Caberfeidh-Mrssanta hat next time there is a review.
