Alpha Ultimate Insulated Jacket - Men's

Polartec NeoShell is a high-performance fabric that is both waterproof and breathable. It allows moisture from your body, like sweat, to escape while preventing rain and snow from entering. This means you can stay dry and comfortable during outdoor activities, making it perfect for hiking, skiing, or any wet-weather adventures.

Polartec Alpha insulation is designed to provide warmth while being lightweight and breathable. Its unique construction allows for better airflow, which helps regulate your body temperature during physical activities. This means you can stay warm without feeling weighed down, making it ideal for active use in cold weather.

A semi-fitted or slim fit jacket is tailored to be closer to your body compared to a loose fit. This design reduces wind resistance, which is especially beneficial for activities like cycling. It also allows for easier layering underneath, ensuring you stay comfortable and agile during your outdoor pursuits.

Double-layer Alpha construction utilizes two layers of Polartec Alpha insulation, enhancing ventilation. This design helps keep you warm while allowing excess heat and moisture to escape, preventing overheating during intense activities. It’s perfect for those who want to stay active without compromising on comfort.

An anatomically shaped cuff design is tailored to fit the natural shape of your wrist, which helps keep wind and water out more effectively. This feature enhances comfort and functionality, especially during outdoor activities in cold and wet conditions, ensuring that you stay warm and dry without sacrificing mobility.

Absolutely! Jackets made with Polartec materials, like NeoShell and Alpha, are specifically designed for high-intensity activities. They provide breathability, moisture management, and warmth without bulk, making them ideal for activities such as skiing, hiking, or climbing, where you need to stay comfortable and agile.
