Baffle construction plays a crucial role in how efficiently a down jacket traps and retains warmth while keeping weight to a minimum. Montane’s Kamen Hoodies use two specialised baffle designs: Offset Boxwall and Nip & Tuck (NAT), each engineered for distinct performance advantages. By improving loft, minimising cold spots, and staying warm without adding bulk, these construction methods play a big part in how each jacket stands up to demanding mountain use.
Baffle Construction
Montane's Kamen XT showcases Offset Boxwall construction, which uses simple but effective design to ensure that the down is actively guided as close to the body as possible. This achieves maximum thermal efficiency without additional materials and weight.
Then, Nip & Tuck (NAT) construction is used in the Kamen Hoodie to loft down towards the body, maximising the thermal performance of the warm-air layer retained by the down.
What are NAT Baffles?
Montane's NAT (Nip & Tuck) baffle construction improves thermal performance by lofting down towards the body.
ExpeDRY™ Goose Down with Real-Gold Tech
The Kamen & Kamen XT are filled with ExpeDRY™ Goose Down, which has non-toxic gold particles bonded to it for fast-drying performance and industry-leading warmth. The chemical-free technology works because gold particles vibrate water molecules, just like heat does, to speed up evaporation at a rate faster than the water absorption rate of down, while managing moisture from the body.
PrimaLoft Active Gold Vent
Added Primaloft Gold synthetic insulation panels in CF collar and shoulders to manage moisture build up and provide durable insulation in high compression areas.
