Heated undershirts

G-Heat's heated base layers, equipped with powerful batteries, provide constant warmth. Perfect as a base layer for your winter activities such as hiking or skiing, or for outdoor work or in cold environments, they ensure comfort and protection.

Designed for winter weather, they're ideal for athletes at high altitude, motorcycle riders, professionals working in cold conditions, and city dwellers. Their versatility makes them essential for all activities in extreme temperatures.

G-Heat provides a detailed size guide (chest, waist, and hip measurements) to guarantee a perfect fit and optimal warmth.

G-Heat's base layers are available in two designs. The long-sleeved seamless heated top features integrated heating technology for precise temperature control, breathable fabric to wick away moisture, and an ergonomic fit that feels like a second skin. The heated midlayer, on the other hand, is a flexible base layer specially designed for static activities or motorcycle riding. It guarantees both freedom of movement and warmth in cold weather.

G-Heat's heated base layers combine cutting-edge technology, ergonomic design and breathable materials to guarantee comfort, freedom of movement and thermal performance for the most demanding users.

That's the big question! To answer it, you need to understand the fundamental difference between the two. It's a bit like choosing between a good blanket and a radiator.

• Traditional thermal underwear (wool, synthetic fibre, etc.): It works on the principle of insulation. It's passive heat. It traps the warm air from your own body to create a barrier against the cold. Ideal for moderate, steady effort where you produce your own warmth. Its limitation? If you're static or your body cools down, its performance diminishes.
• G-Heat heated base layer: This one creates its own heat. It's active, adjustable warmth. Thanks to its battery, it generates a heat pulse that doesn't depend on your effort. Ideal for static activities (motorcycle riding, stationary hunting, shift work) or intense cold conditions where insulation alone isn't enough. It ensures you constant warmth, whether you're moving or at rest.

Think heated base layers are reserved for polar expeditions? Think again! It's the well-kept secret of everyone who's decided that cold won't dictate their day any more. Whether you're a professional braving the elements, a winter sports enthusiast, a road warrior, or simply someone who wants to transform winter into a season of comfort, we've got you covered.

Ready to take the plunge towards a winter without shivers? Excellent choice! To find the heated base layer that'll become your ally, you just need to ask yourself the right questions. As your coach, I'm giving you the 3 key points to check for a successful purchase.

• Heating zones: A good heated garment doesn't heat randomly. It delivers precise warmth to strategic areas of the body: the back, lower back, stomach... Where cold strikes first. This targeted approach guarantees an enveloping warmth sensation and maximum performance.
• Material and fit: For a base layer to work effectively, it needs to be worn close to the body, like a second skin. A close fit and breathable fabric allow heat to be delivered directly to the skin and moisture to be wicked away. It's the winning combination for optimal comfort, even during physical effort.
• Power levels: The weather changes, so do your needs. A product with several heating levels offers incredible versatility. A low setting for a crisp morning, a high level to tackle a sudden temperature drop... You're the one in control.

Simply connect the battery, activate the heating by pressing a button, and wait 10 minutes until optimal warmth is reached. A second press of the button allows you to adjust the intensity, which is indicated by a coloured light or bars depending on the design. It's as simple as that!

Remove the battery before washing. Use a mild detergent without fabric softener and wash the garment by hand or in a machine at 30°C with a minimum spin. Avoid using a tumble dryer, bleach, or dry cleaning. Don't wring out the garment to avoid damaging the heating system.

Want to get the most out of your heated base layer? It's easy. With a few good habits, you can extend heating time and enjoy your cocoon of warmth for even longer.

• Warm up in advance: switch on your garment 5 to 10 minutes before heading out. By the time the heat spreads, your body will already be in optimal conditions.
• Don't start at maximum: unless you're heading out into a blizzard, there's no need to set the highest level straight away. Start at the medium setting, let your body adjust, then tweak if needed. You'll save precious battery time.
• Play with the levels: stopping for a break in the sun? Drop down a level or pause. Wind picking up? Increase the power. Actively managing heating levels is the best way to use exactly what you need, when you need it.
