Protium Jacket – Past Season Colours

Jump to: Our Verdict / Features / Specifications

Warm and breathable the updated Protium Jacket hits a sweet spot between comfort and sustainability for mountain layering.

Montane says: 

The Montane Men’s Protium Fleece Jacket delivers warm, lightweight breathability that helps you to do more, wherever your adventures take you. This high-performance garment is constructed with more than 90% recycled materials, from the fabric to the zips. When you need a versatile, lightweight, multi-season layer that you can take deep into the forest and high on the mountain, the Montane Men’s Protium Fleece Jacket won’t let you down.

Our Verdict

At 381g (medium), the Protium sits comfortably in the mid-layer bracket, offering reliable warmth from its Thermo Grid fleece without tipping into bulk. I’ve found the cut trim but not restrictive, with enough stretch in the fabric to move easily. The collar sits snugly and the fleece breathes well when working hard, making it a strong choice across a range of seasons.

Over 90% of the fabric and components are now recycled, which doesn’t change the feel on the trail but does add some peace of mind. Pocket placement is fine for everyday wear, though a pack hipbelt can partially block access. The cuffs and hem sit cleanly, and the finish overall feels durable without being heavy-handed.
