THMO Mens Knitted Beanie Hat Did you know that you lose the majority of your body heat from your head You might think your feet or your hands are where you lose your internal heat because they are stone cold. But, it is your head, as it is usually warm and escapes through there. These mens THMO hats are designed to keep the heat in. They are a great winter accessory to keep not just your head but your whole body. These mens THMO hats are made from 100% acrylic. Acrylic is one of the best man made fibres that is especially designed to keep you warm, whilst also possessing a soft touch. It is also a good thermal insulator, holding warm air close to your head and trapping the heat that is generated by your head. The cuff also hugs the side of your head firmly so that heat can not escape though the sides of the hat. The hat also has a turnover cuff, so you can wear the hat cuff turned over or you can straighten the hat out to give you some extra length. On the cuff is the black THMO badge stitched into the front of the hat. The hat is an original knitted style. These mens THMO beanie hats are made in one size and they are available in 2 different colours including jet black and dark grey. They are made from 100% acrylic and they are safely machine washable.
