Designed and engineered in Japan, where sailing remains a hugely popular leisure pursuit, the Heatrub Ultimate Baselayer has been independently tested at the iconic Boken Institute in Osaka, resulting in a warmth retention rating of 0.78: a standard baselayer would have a rating of 0.1-0.14, while a sweater would have a rating of 0.3. It performs at its best in a temperature range of -10° Celsius thru 10° Celsius – so even in the coldest of conditions, the Ultimate has got your back.

A standard baselayer traps body heat between your skin and the material, so it takes a little time before you feel the benefits. With Zerofit, five separate fabrics, along with a patented knitting process, create instant warmth as soon as you pull it on. The Ultimate is also the baselayer for sailors who hate traditional baselayers! We don’t engineer our products with compression for heat as a technology, unlike other brands. The unique fabric mix means you don’t need the tightness in order to activate the baselayer, making it a much more comfortable proposition.

Innovative ‘Heat Threads’ positioned on the inside of the garment gently rub against your skin as you move, which creates positive warmth across your body, and also means this instant heat is retained.

The Heatrub Ultimate is available in black, grey, red, navy, green and winter white in sizes from XS-3XL.
