Sometimes you need just the barest of hats. Maybe you’re fighting a cool breeze as you traverse a ridgeline, or bike-commuting on a brisk October morning, or starting chilled on a sunrise trail run. This 100-percent merino cap will be your go-to three-season and winter-workout hat—and it fits under any helmet (and in any pocket when you warm up and tuck it away).
The wool is as soft and supple as cotton, but wicks and breathes better, and it creates so little stink that one tester still hasn’t laundered his after more than 30 uses. (A more picky editor washes hers repeatedly and reports no shrinking or pilling.)
Key feature: The fit is longer than traditional beanies, which delivers exceptional ear coverage.
