Description
The Zerofit Heatrub Ultimate leggings are a premium base layer with unmatched warmth, heat retention technology, and a stretchy, non-restricting fit.
These leggings are made from the same material as the Zerofit Heatrub Ultimate shirt, an award-winning and independently tested baselayer proven to be five times warmer than similar garments. Comparable to fleece-lined overtrousers, these leggings come with the added benefit of four-way stretch for active sports and heat retention in the coldest conditions.
The secret to this superior warmth lies in their revolutionary ‘Heat Threads,’ woven into the fabric of the garment and activated with the slightest movement. These threads gently brush against your skin, instantly generating positive warmth without requiring compression or tightness to keep you warm or the need for additional layers on top.
As the Heatrub Ultimate doesn’t rely on compression for heat, the leggings are made from a four-way stretch fabric, allowing for an incredible range of movement without restriction, while generating and retaining warmth.
Tested rigorously at the prestigious Boken Institute, Japan’s leading testing organization, the Heat Retention Rating of 0.78 sets the Heatrub Ultimate far apart from standard baselayers, which typically range from 0.1 to 0.14, making the baselayer the perfect companion for outdoor activities in the most extreme temperatures.
Machine washable, moisture-wicking, and proven to work in temperatures between -10° Celsius and 10° Celsius, the Zerofit Heatrub Ultimate does the work of multiple layers, making it a cost-effective thermal solution.
