Why a heated baselayer makes all the difference in winter
When engaging in outdoor activities — skiing, mountain hiking, trekking, winter walking, expeditions — thermal comfort is often the key to enjoyment, performance and safety. A traditional base layer may be sufficient for moderate use, but as soon as temperatures drop or conditions become hostile (cold, wind, snow, altitude), it may not be enough.
A heated base layer provides active, controllable warmth—it no longer relies solely on passive insulation, but adds heat on demand. So even if the body loses heat or activity slows down (break, climb, wait), the baselayer continues to maintain a comfortable temperature. This reduces the need to layer up and improves comfort, mobility and overall thermal protection.
What Therm-ic Heated Baselayers offer
-
Even & adjustable heat — Thanks to integrated technology (S.E.T® heating line), heat is distributed evenly across the torso (front and back). You can adjust the intensity according to conditions: exertion, cold, rest, etc.
- Moisture wicking & breathability — Even when heated, the baselayer is technically designed to wick away perspiration thanks to ventilated areas (e.g. ‘Moisture-Vent’ technology on Therm-ic) — which prevents the ‘cold + damp’ effect and maintains comfort during exercise.
-
Thermal insulation + comfort even when stationary— ‘Buffer‑Cones’ and thermoregulating knits provide effective insulation to retain body heat, even when the body is stationary (breaks, chair lifts, waiting).
-
Freedom of movement & reduced bulk— Unlike heavy layers, the heated baselayer remains fitted, thin and flexible: ideal for skiing, hiking, climbing and technical movements—without being bulky or cumbersome.
-
Versatility: sport, outings, intensive use or leisure — Whether for intense activities (skiing, mountaineering, hiking) or more moderate use (walking, city), the heated baselayer adapts: it combines thermal comfort, practicality and simplicity.
Who are these heated baselayers for?
- Winter sports enthusiasts, hikers, trekkers, mountaineers — who are active in cold, long, changing conditions.
- People who are sensitive to the cold, to their extremities or to thermal regulation — who are looking for comfort and lasting thermal support.
- Those who want a good compromise between warmth, lightness and mobility — without layering up with thick clothing.
- Versatile users — skiing, mountaineering, outdoor activities, but also city life, commuting, everyday use in winter — who want an ‘all-terrain’ baselayer.
- Those who seek simplicity, comfort and efficiency — the heated baselayer replaces several layers, makes getting kitted out easier and offers intelligent thermal autonomy.
Best practices & expert advice
-
Check the battery life and charge the battery before heading out — our heated base layers require an external battery, the ‘Body-Pack’. Make sure it is fully charged to maximise battery life and comfort.
- Adjust the intensity according to the effort and weather — when climbing or exerting intense effort: moderate heat; when stopping, cold, or riding the chairlift: stronger heat. This optimises usage and battery life.
- Combine the heated base layer with suitable layers — insulated or windproof jacket, trousers, gloves, technical socks, for complete comfort.
-
Care for the garment properly— remove the battery before washing, wash gently at 30°C, dry flat, no fabric softener or bleach—to preserve the heating elements and thermal properties.
- Wear a snug but comfortable fit— so that the heating system is effective and to facilitate heat circulation without uncomfortable compression.
