At OMC, we’re passionate about quality — so partnering with Zerofit was an easy choice. Their baselayers are trusted worldwide for their warmth, comfort, and performance. We’re excited to offer some of our favourite Zerofit pieces, carefully selected with anglers in mind.
The most popular baselayer across the entire collection, 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.
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 and the construction of the Zerofit Heatrub Ultimate means the heat is retained.
Unlike other baselayers, the Ultimate does not work on the basis of 'compression for heat' - so not only does it provide greater warmth, but you also won’t feel restrained by an inability to move freely, making it one of our most comfortable baselayers.
It also features a slightly looser neckline design, which allows some heat to travel out away from the body - during testing and development of the Ultimate, a tighter neckline was found to cause some overheating.
A rigorous product evaluation at the iconic Boken Institute - Japan's leading testing organisation - 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.
Regardless of where your passion is fishing takes you – the Ultimate has got you covered in temperatures as low as minus 10° Celsius.
And because it's so good at keeping you warm, there's no need to 'layer up' with bulky additional clothing - the Ultimate does the work of multiple layers which also makes it a cost-effective heating solution.
