The "CATALDI-S3" down jacket features Boudin quilting technology for enhanced cold protection. This model is part of the ACQUA series, boasting high water resistance and is "ACQUA RESISTANT (water-repellent)." The short length and compact silhouette prevent bulkiness, resulting in an attractive finish. I usually wear a size 48, but this product fits a bit tight.
