The Tuvegga Sport Air Woman 3/4 Long Johns by Devold are the right three-quarter briefs when the going gets tough. You can wear them on both sides. One side with a flat surface with high breathability, the other with 3D air channels for extra insulation. The merino wool makes them pleasantly warm, breathable and temperature-regulating. The small addition of elastane ensures elasticity and optimum freedom of movement. The high waistband provides comfort and a perfect fit. The wool also makes them anti-odour. This means you can wear them for several days without having to wash them, which can be very pleasant on multi-day tours. The three-quarter length of the legs is ideal in combination with ski boots, ski touring boots or high mountain boots.
