Thin but warm! The new Midweight Merino Wool Hat from our friends at Buff is just what you need as the temperatures start to cool. The benefits of merino wool are many: it’s naturally odor resistant; it’s warm in moderate to cool temperature; it’s breathable, moisture wicking, and dries quickly; it’s machine washable; and it retains heat, even if it gets wet. This hat has a snugly comfortable fit, a clean, simple look, and is thin enough to wear under a bike or ski helmet. It’s also small enough to slip into a pocket, so you can always have it handy. Keep your head warm and insulated with the Buff Midweight Merino Wool Hat!
