Heatrub Merino Wool Baselayer Is Back – Grab It Now at the Lowest Ever Price This Black November!

While the Heatrub Ultimate remains our best-selling baselayer, we know many of you can’t get enough of the luxurious comfort of the Zerofit Heatrub Merino Wool Baselayer. This premium piece, crafted in Japan, has just been restocked and ready to keep you cozy all winter long.

Combining exceptional warmth with the naturally soft feel of Merino wool, it’s the perfect choice for anyone who values both performance and comfort. Whether you're hitting the slopes, heading outdoors, or just braving chilly mornings, the Heatrub Merino Wool Baselayer delivers a touch of everyday luxury that keeps you warm in style.

Exclusively crafted and produced in Japan — the birthplace of the Zerofit brand — our Merino Wool Baselayer offers a luxuriously soft feel against the skin while keeping you comfortably warm, even in temperatures as low as -10°C.

Available in classic black and white, this unisex baselayer perfectly blends style, comfort, and performance. It was also tested for its thermal efficiency in the same Heat Retention Test as our award-winning Heatrub Ultimate Baselayer, proving it’s a reliable choice for staying warm without compromising on softness or quality.

Interest in active and outdoor sports such as American golf and skiing is not just for masculine individuals. It may also be true for the gentler ones, especially those with delicate skin. So, if you belong to this group and want gear that best suits you, then the Zerofit Heatrub Merino Wool Baselayer should be an excellent purchase for you.

The Heatrub Merino Wool Baselayer is expertly crafted from a premium blend of 75% Merino Wool, 17% Acrylic, and 8% Polyurethane. The choice of Merino Wool is no coincidence — it’s renowned for its superior moisture and temperature regulation. It returned a CLO Rating of 0.42 - a standard baselayer would have a rating of 0.1-0.14 – making it THREE TIMES WARMER than a regular product.

This advanced fabric is specially enhanced to absorb and dry sweat quickly, preventing the discomfort of cold, damp skin. As you move, the material efficiently wicks away moisture and releases it as vapor, keeping your skin feeling dry, fresh, and comfortably warm no matter how active your day gets.

Beyond its incredible warmth and comfort, the Heatrub Merino Wool Baselayer is carefully treated to enhance its moisture-wicking capabilities, ensuring you stay dry even during intense activity. To address the natural challenge of wool fibers and bacteria, the fabric is equipped with antibacterial properties that help prevent odor buildup, keeping you feeling fresh all day long.

Additionally, by blending premium Merino Wool with a special synthetic fiber, Zerofit has made this baselayer easy to wash, durable, and perfect for sensitive skin.

The result is a luxurious, high-performance baselayer that not only shields you from the cold but also delivers exceptional comfort for all skin types. With Zerofit USA, you’re guaranteed authentic Japanese craftsmanship and top-quality products—like the Heatrub Merino Wool Baselayer.

The Heatrub Merino Wool Baselayer arrives beautifully presented in a premium rose-gold colored box, reflecting the luxury and craftsmanship that define the Zerofit brand. This elegant packaging not only enhances the unboxing experience but also makes it an excellent gift choice for anyone who values comfort, warmth, and quality.

Whether you’re purchasing it for yourself or as a thoughtful present, the Merino Wool Baselayer’s stunning presentation perfectly complements the superior performance waiting inside.
