Warmth is crucial for fleece jackets, especially in chilly mountain conditions. A jacket that provides excellent warmth ensures comfort and safety during outdoor activities. The Rab Ascendor Light Hoody excels in this category with its high warmth-to-weight ratio, making it ideal for cold conditions.
