Stay Warmer This Season with the Zerofit Heatrub Ultimate Base Layer

Are you someone who loves the outdoors but dreads the cold creeping in? ❄️ Whether it’s walking, hiking, cycling, playing football, snowboarding, gardening, biking,  skiing, or just enjoying your favorite winter sport, staying warm without feeling restricted is key.

That’s where the Zerofit Heatrub Ultimate Unisex Base Layer comes in – your perfect cold-weather sports companion. Unlike traditional base layers that can feel tight, heavy, or limit your movement, the Heatrub Ultimate is designed to give you maximum warmth and complete freedom.

Built especially for skiing and other freezing conditions, this baselayer doesn’t just shield you from the cold – it actively keeps you warm while letting your body move naturally. The result? No more layering hassles, no stiff or bulky clothing, just lightweight comfort and reliable warmth wherever your adventure takes you.

If you’re serious about outdoor sports and refuse to let cold weather hold you back, the Heatrub Ultimate Base Layer is exactly what you need.

The Heatrub Ultimate Baselayer isn’t just warm—it’s been independently tested at the Boken Quality Evaluation Institute and scored an impressive 0.78 for heat retention. To put that into perspective, a standard baselayer typically scores between 0.1 and 0.14.
What sets it apart from most thermal layers is its innovative design. While typical baselayers rely on compression to trap your body heat, the Heatrub Ultimate uses special Heat Threads woven inside the garment. These fibers generate warmth instantly, keeping you cozy from the moment you put it on—even in the coldest conditions.

The Heatrub Ultimate generates up to five times more warmth than a standard baselayer, making it our best-selling favorite for cold-weather adventures. Its super-soft Heat Threads trap warmth instantly without tight compression, giving you unbeatable comfort and freedom of movement.

Available in six stylish colors—red, green, black, grey, navy, and winter white—and sizes from XS to 3XL, it’s the perfect fit for every outdoor enthusiast.

The Zerofit Heatrub Ultimate Base Layer isn’t just about keeping you warm—it’s designed for complete freedom of movement. Thanks to its patented knitting process and innovative blend of five fabrics, it adapts perfectly to both slower-paced and high-intensity activities.

Ideal for the coldest weather conditions, the Heatrub Ultimate protects you from chilly to freezing temperatures while you enjoy your favorite outdoor sports.

At Zerofit USA, you can easily get the authentic Heatrub Ultimate along with other premium Zerofit gear.
