Our Verdict

The Montane Caldus Jacket delivers exceptional warmth and breathability, making it a versatile mid-layer for cold-weather activities or cosy casual wear.

The high-pile THERMO HL fleece excels in trapping heat while remaining highly breathable, effectively managing moisture during high-output pursuits. It’s soft and comfortable against the skin, and the mechanical stretch ensures unrestricted movement, whether you’re scrambling over rocks or layering up around camp. The regular fit works well over a base layer and comfortably accommodates an outer shell when conditions demand it.

 The stretch cuffs, hem, and high collar ensure a snug fit that seals in warmth, while the full-length front zip makes it easy to regulate temperature during activity. At 440g (size M), it’s lightweight enough for all-day wear without feeling cumbersome.

This is one of those versatile “year-round” pieces, equally at home on the hills, keeping you warm around camp, or adding a touch of comfort at home.
