How can brands reduce defects in custom puffer jacket production?

Brands can reduce defects in custom puffer jacket production by confirming the shell fabric, filling type, quilting pattern, lining, zipper quality, hood construction, cuff details, and packing method before bulk production. Common puffer jacket risks include uneven filling, inconsistent quilting, weak seams, zipper problems, measurement variation, and compressed packing issues. Mature brands should approve a pre-production sample and define inspection points for filling distribution, warmth structure, stitch tension, color matching, logo placement, and hardware function. Bulk inspection should compare production pieces against the approved sample and written specification.
