The Montane Caldus women's fleece jacket is designed to provide exceptional warmth in the coldest winter conditions while maintaining high breathability for dynamic mountain activities. It is crafted from high-performance THERMO HL fabric, consisting of 100% polyester (including 70% recycled polyester). This advanced high-loft fleece structure effectively traps warm air around the body while managing moisture to prevent overheating during intense exertion.

The jacket's design incorporates mechanical stretch for unrestricted freedom of movement and a low-profile seam construction that minimizes chafing and ensures long-lasting comfort when worn under a hard shell or on its own. With a total weight of just 339 g, it is remarkably lightweight and comfortable for all-day wear, whether hiking, climbing, or ski touring.

Functionality is enhanced by two large front pockets with YKK zippers for secure storage of essentials, along with a full-length YKK front zipper for easy temperature regulation. A high collar offers extra thermal protection against the cold, while the subtly elasticated hem and cuffs ensure a snug fit and prevent heat loss.
