Independently tested at the iconic Boken Institute in Osaka, the Ultimate has proven to be five times warmer than leading competitors, so whether your passion is fishing, walking, hiking, farming, sailing, gardening, bowling, bird watching, snowboarding, skiing, photography, motorcycling, golf or equestrian sports – the Ultimate has got you covered, even in the coldest of conditions. It’s also the perfect baselayer to wear when watching your favorite sport or team in an icy cold stadium.
Testing at the Institute resulted in a heat retention rating of 0.78; a standard baselayer would have a rating of 0.1-0.14, while a sweater would typically have a rating of around 0.3.
Extra-long ‘Heat Threads’ on the inside of the garment (you can actually see them) gently rub against your skin as you move. This creates frictional heat which means that instant warmth is retained, and the Ultimate has been designed to work in a temperature range of 14° - 50° Fahrenheit.
