Men's Insulated vest Bergans MountainLine Light Insulated Air Vest Men Dark Shadow Grey 2026

The men's vest Y MountainLine Light Insulated Air Vest by the Norwegian brand Bergans of Norway is the pinnacle of modern technology in the production of hiking equipment for professional use in high mountain environments. Ultra-light, technical, and extremely comfortable, it uses a unique combination of materials to provide both elasticity, durability, excellent ventilation, and warmth. The perfect mix of synthetic and natural materials creates ideal thermoregulation without making the garment overly delicate, so it can serve you in the most brutal conditions.

The Y MountainLine Light Insulated Air Vest is a vest made from merino wool and Cordura Technostretch, representing an innovation in the field of mid-layer gear for mountaineering, hiking, and ski touring. It is lightweight and technical, and the combination of materials makes it both breathable, functional, and highly durable and resistant to mechanical wear. The light synthetic insulation Vivo Performance: Eco provides a perfect balance between low weight and thermal insulation.

The model is part of the limited high-tech Y MountainLine series by the Norwegian brand Bergans of Norway, which focuses on the needs of professional athletes and high-mountain adventure enthusiasts. The overall design and features are intended to provide the necessary protection from weather conditions, even in extreme situations.

Merino wool is known for its properties as a natural thermoregulator, maintaining an optimal temperature close to the skin, providing warmth even when wet, resisting unpleasant odors, and supporting the balance between heat retention and breathability. That’s why merino wool garments are highly preferred as a mid-layer for mountaineering and high-intensity activities such as alpine climbing, rock climbing, and ski touring. A potential drawback of this material is that it dries slowly and is delicate, thus more prone to tearing. In the Y MountainLine models, this issue is resolved with the use of Cordura® Tecnostretch fabric with a ceramic print—an extremely durable, strong, and water-repellent material that repels water droplets, blocks wind, and provides effective protection against the dynamic weather changes you may encounter in the mountains.

The Bergans Y MountainLine Light Insulated Air Vest uses a special insulation material called Vivo Performance: Eco, also known as Clo insulation—this is a European synthetic insulation developed specifically to maintain optimal breathability of the fabric while preserving your body’s warmth. The fabric is constructed with micro-perforated pores inside, which increase breathability by 30% by allowing water vapor to pass through the fabric more quickly. The micropores are small enough to prevent air circulation, thus maintaining high thermal insulation properties. Vivo Performance: Eco is made from 93% recycled fibers, extruded from PET bottles—in full alignment with the values of Bergans of Norway, who actively participate in various environmental protection programs.

The Bergans Y MountainLine Light Insulated Air Vest is equipped with two front pockets and one zippered chest pocket. One of the front pockets also serves as a compression sack for the entire vest. Inside the pockets, you'll find a soft wool lining to warm your hands on chilly days. The front pockets are positioned higher to avoid interference when wearing a backpack hip belt or climbing harness. A seamless construction is used in the shoulder and side areas to eliminate the risk of chafing.

The Bergans Y MountainLine Light Insulated Air Vest is designed for high-mountain adventure enthusiasts—the refined combination of high-tech materials makes this model lightweight, warm, very comfortable, yet breathable, elastic, and abrasion-resistant.
