Zerofit Heatrub Ultimate Baselayer - Black

Game-Changing Warmth and Comfort

Our Most Popular Baselayer

The award-winning Zerofit Heatrub Ultimate is a best-in-class, game-changing baselayer that has been independently tested and proven to be five times warmer than leading competitors and twice as warm as a sweater.

Advanced Heat Threads Technology

Technologically enhanced 'Heat Threads' inside the garment are activated through even the slightest of movements, gently brushing against the skin to generate positive warmth instantly. The construction of the Heatrub Ultimate means that this heat is retained.

Unrestricted Freedom of Movement

Unlike other baselayers, the Ultimate does not rely on 'compression for heat.' This design not only provides greater warmth but also ensures you won’t feel restrained by an inability to move freely, making it one of our most comfortable baselayers.

Optimal Neckline Design

The Ultimate features a slightly looser neckline, allowing some heat to travel away from the body. During testing and development, a tighter neckline was found to cause overheating. This thoughtful design keeps you comfortable.

Exceptional Heat Retention

A rigorous product evaluation at the iconic Boken Institute, Japan's leading testing organization, resulted in a Heat Retention Rating of 0.78. For comparison, a standard baselayer would have a rating of 0.1-0.14, and a sweater would typically have a rating of around 0.3.

All-Weather Versatility

Whether you’re passionate about fishing, hiking, motorcycling, golf, equine sports, sailing, skiing, gardening, or you spend a great deal of your working day outside, the Ultimate has got you covered in temperatures as low as minus 10°C.

Cost-Effective Heating
