Montane Caldus Fleece provides optimal warmth in demanding winter conditions, while being constructed to breathe well – even when worn under a shell jacket. The high-pile fleece surface retains heat by creating an insulating air layer around the body, while the material stretches with your movements for maximum comfort.

The seams are low-profile and designed to work seamlessly over a base layer, providing high comfort and durability in tough environments. The Caldus is a reliable mid layer that keeps you warm when the temperature drops and conditions become challenging.
