When the mountain demands determination and weather conditions shift without warning, the Lithium 40k Jacket Woman delivers reliable technical protection in a FAST&LIGHT format. Designed for ski mountaineering, alpinism, and outdoor activities, its 3-layer 20D construction balances durability, lightness, and precision in every movement.
Its membrane, rated at 20,000 mm waterproofness and 40,000 g/m²/24h breathability, creates an effective barrier against rain, snow, and wind, maintaining a stable internal microclimate during intense ascents. The women-specific pattern optimizes fit at the shoulders, waist, and hips, enhancing ergonomics without restricting mobility. The helmet-compatible hood and harness-accessible pockets reinforce its alpine character, while the minimalist design broadens its versatility for less technical terrain. A versatile third layer engineered to move fast, light, and with maximum efficiency in the mountains.
