Waterproof and taped seams: This piece will keep you dry thanks to a waterproof membrane and taped seams, ensuring not a drop of water gets in, even in heavy downpours. We confirmed this by leaving the piece under the shower for 10 minutes, then checking that the inside is still perfectly dry. Ultra warm / down to -25°C: This piece is among the warmest of the season, with a cold protection level of 3/3. It is ideal for blizzards or extreme temperatures, down to -25°C. BREATHABLE: This comfortable material keeps you dry by wicking away sweat to prevent a damp feeling. We measure how well water vapour can pass through the material; the more it circulates, the more your clothes breathe.
