These 100% Merino Wool beanies (aka touques, stocking caps, knit hats, etc) are staple pieces of gear when conditions are liable to get chilly. Stuff one in your bag and stay warm wherever your ride takes you. Perfect for covering up your helmet hair or a chilly night in your sleeping bag.
One size fits most. Folks with bigger domes may find the fit a little snug at first but it will break in.
From Surly: "Grandma always said, ‘you lose 75% of your body heat through your head.’ Now, we aren’t doctors, but we’re smart enough to know not to mess with Grandma. Wear your wool hat."
