Montane Flux black is your go-to winter insulated jacket that can be worn on its own or as a base layer. Unlike natural down, the synthetic filling in this jacket maintains incredible performance even when wet. Plus, it's windproof, weather-resistant, warm, and breathable, making it a fantastic choice for all types of winter climbing adventures.

The jacket’s exterior features Pertex® Quantum ECO fabric, which provides excellent protection against wind and snow while being made from recycled materials. Inside, it’s packed with the reliable Primaloft® Silver synthetic insulation, known for its long-standing effectiveness in harsh conditions. Each fiber of the Primaloft insulation is coated with a durable water-repellent treatment, meaning it hardly absorbs moisture and dries out quickly. These fibers are ultra-fine and soft, allowing for easy compression while springing back to give you that necessary warmth.

You’ll find a fully insulated and well-fitted hood that accommodates climbing helmets comfortably. The hood is easily adjustable with an elastic cord at the back, snugly fitting around your head. For storage, there are four external zippered pockets, including two hand pockets and two chest pockets, as well as a handy internal pocket for water or gloves. The cuffs feature a partially elastic and Velcro closure, ensuring a snug fit around your wrists and gloves. Plus, the hem can be easily tightened with special drawstrings even when wearing gloves.

• Primaloft®Silver – the most environmentally friendly insulation, comprised of 70% recycled materials. The incredible softness and water-repellent finish make it suitable for use in wet weather, ensuring warmth is easy to achieve. Additionally, the material has high compression properties and feels like natural goose down.
