The Tech Under Helmet Beanie by Mons Royale is a small, space-saving knit cap that fits under your helmet and protects you from the cold and wind. The beanie is made from 190 merino wool, is skin-soft, has flat, unscratched seams and can do all the things that products made from merino wool can do: Breathe, inhibit odors, regulate moisture and temperature and protect you from UV rays if you're ever on foot and without a helmet.
