Built for the bitterest mornings, long approaches, and damp alpine weather, the DownWool 270 Jacket blends the natural strength of alpine wool with premium down to deliver powerful, reliable warmth. Its innovative DownWool® by Grüezi Bag® insulation (70% down, 30% wool) thrives where ordinary down falters, maintaining loft, heat, and comfort even in humid, high-output conditions. Wool absorbs excess moisture, protects the down’s structure, and helps regulate your temperature—so you stay warm without overheating.

A windproof, water-resistant Pertex® Quantum Pro shell shields against driving snow and cold gusts, while targeted wool-blend padding at the sides and underarms maintains mobility without sacrificing insulation. Thoughtful details—like a helmet-compatible hood with refined 2-in-1 adjustment, soft chin inserts, and generous pockets with a removable mesh pouch—round out a design crafted for deep-winter performance.

When conditions turn unforgiving, this is the layer that rises to meet them.
