Beige knit beanie using 3M Thinsulate insulation. This is a very cute and fluffy knit hat ✨️ It also has a brushed lining, so I think it will be very warm when you wear it! I have kept it in the closet since I bought it without wearing it even once. 3M™ Thinsulate™ high-performance insulation was developed to make you more comfortable in the cold season. It achieves excellent insulation due to its fine fiber structure. It's a technology that makes "warm and not thick" possible. Based on scientific analysis, it is used worldwide in winter sports wear, town casual wear, fashionable wear, gloves, boots, hats, and bedding, delivering slim and comfortable warmth.
