A Merino Winter Cap is a staple in almost every cyclist's wardrobe, and for good reason. Relatively light, they're comfortable and easy to carry or wear when you're off the bike. The Merino Winter Cap is thin enough to fit under helmets, with an updated panel construction that reduces bunching, too. The brim has also been shortened a bit (compared to some caps), for better upper peripheral vision without reducing the ability to block sun and rain.
