The Etape SIERRA W women's hybrid sweatshirt will keep you warm in any weather. Modern NanoLoft hollow-fibre material has been used in the chest and back area. Its exceptional thermal insulation properties remain unchanged even during increased humidity caused by higher physical activity. The sleeves and side panels are made of SuperDryntex fabric with insulation which also makes the sweatshirt sufficiently breathable. Recommended temperature range -5 °C to +10 °C.
