When the temperature drops, this HeiDmai beanie has got your head covered – literally. It's a unisex knit skull cap that's all about warmth without the bulk. The outside is made from a premium, stretchy acrylic knit that feels soft and has a nice hand-knitted texture. The inside is where the magic happens: it's fully lined with a super soft, thermal fleece that traps heat like a champ. It's incredibly cozy against your skin. The fit is elastic and stretchy, fitting head circumferences from about 22 to 23.6 inches (56-60cm), so it's a comfy one-size-fits-most for both men and women. The dimensions are roughly 9.1 inches long by 8.7 inches wide. It's perfect for any cold-weather activity: hiking, camping, skiing, running, cycling, or just walking the dog. The Dark Khaki color is versatile and pairs easily with all your winter jackets and sweaters. It also makes a fantastic, practical gift for anyone in your life. Stay warm in style!
