Editorial Note Moncler applies its cold-weather expertise, rooted in the label's Alpine origins since Grenoble in 1952, to the 'Rivau': a full-length down jacket built for serious winter. The shell is 100% polyamide with boudin quilting packed with goose down, while the high neck is lined with a ribbed wool knit for added insulation at the collar. An adjustable hood extends the protection further. Layers cleanly over casual T-shirts for an effortless off-duty contrast in bold orange. Size & Fit Fits true to size. Take your normal size. Regular fit, with a generous length through the body and clean volume at the shoulders. Mid-weight to heavyweight shell; substantial goose down fill provides genuine thermal insulation. Details and Care Material: 100% Polyamide shell; ribbed wool knit collar lining; goose down fill Closure: Zip closure Colour: Orange Made in: Romania Care instructions: Hand wash Frequently Asked Questions Does the Rivau fit true to size, or should I size up for layering? The Rivau fits true to Moncler's standard sizing. If you plan to layer a mid-weight knitwear piece underneath, selecting the larger of two adjacent sizes will give you a more comfortable range of movement without affecting the outer silhouette. How warm is boudin quilting compared to standard channel quilting? Boudin quilting creates rounder, more voluminous baffles that trap a greater volume of goose down per section. This distributes insulation more evenly across the jacket and reduces cold spots at the seams, making it notably warmer than flat or narrow channel-quilted alternatives at the same shell weight. How should I care for a goose down jacket? Hand wash in cold water with a specialist down detergent, then tumble dry on low with a clean tennis ball to restore the fill's loft. Avoid dry cleaning, as solvent-based processes can strip the natural oils from the down clusters and reduce long-term insulation performance.
