Updated with a fully fitted four-piece hood and refined construction details, the latest Fusion is built for cold-weather travel, winter camp use and everyday wear in alpine and cold-weather conditions.

The Fusion uses a Japanese-made Hydronaute XT™ 20D ripstop shell with 20k waterproof protection, 25k breathability and a high-performance PFAS-free DWR. Using the same advanced Hydronaute XT™ membrane technology found in our expedition down jackets, the Fusion provides greater protection from wind, frost, snow and light precipitation than many down jackets in its category.

In light precipitation, the Fusion can function effectively as an outer layer, while the fully windproof shell helps protect the down insulation and maintain loft and thermal performance in changing conditions.

Premium 800+ loft RDS certified white duck down is paired with box wall construction to maximise loft, reduce cold spots and improve thermal efficiency. G-LOFT® ECO EVOX synthetic insulation is used through the hood visor and face shield, maintaining insulation performance in high-moisture areas.

Additional features include hidden tuck-stitched seams, fleece-lined hand warmer pockets, internal storage pockets and a relaxed fit designed for layering systems.
