Heat Holders’ creators always seem to come up with innovative ideas to keep us warm no matter what. Here is an example, combining their improved version of the original heat weaver thermal lining technology and the classic reflective hi-vis that workers and cyclists alike definitely need on those cold and dark winter nights. The Heat Holders / Workforce collaboration allows this synergy of knitting technologies to become relevant to working and outdoor environments The turnover hats boast a 4.7 tog rating, higher than the original Heat Holders mens turnover hat and much warmer than your standard acrylic hat. This is thanks to the new and improved heat weaver lining within the hat, a plush fur-like thermal lining that maximizes the amount of warm air held close to the head. Special Heat Holders yarn also provides high performance insulation against the cold and has superior moisture wicking breathing abilities. A stretchable knitted construction also allows the hat to fit around the natural contours of your head, improving warmth and comfort Heat Holders hi-vis hats come in 3 colours including bright orange, bright yellow and black. The two lines that strike on the turnover section of the hat are reflective bands that allow light to bounce off for higher visibility in the dark. Our hats are available in one size and are 89% acrylic and 11% polyester on their outer and 100% polyester inside. They are also machine washable.
