Furry boots , maxi knit sweater, bonnet-scarf-gloves outfit: when the temperatures fall sharply, all the survival tips are good to take. But the practice of combo "pantyhose / pants" is actually not as effective as it seems ... Explanations.

In theory, multiplying the layers to warm up his legs may seem like a genius idea. But in practice, this association produces exactly the opposite effect.

Indeed, the wearing of synthetic tights under jeans prevents the skin from warming the air contained inside the jeans. Consequence: the air remains cold and ice our favorite pants ... and our legs at the same time. A feeling of intense cold then accompanies each of our steps. Suffice to say that it was not really the desired effect.

The solution ? Opt for wool tights, rather than elastane, or cotton leggings, to avoid this rather unpleasant consequence. We think above all efficiency and comfort. To hell with glamor, in winter the survival instinct takes precedence over style .
