We took the brim off. And when you make a cap this sturdy, that's no small affair. It was a big job, cutting into the craftsmanship of our original cap, but the guys and gals in our snowmobiling group wanted something snug under their helmets, and we couldn't help but oblige. The result is a premium wool-blend, soft-lined cap you can wear under anything for as long as you own your head.
