The custom jacket sampling process usually starts with project review. The manufacturer checks the design, fabric direction, trims, size chart, logo files, construction details, and expected quantity. After the key details are confirmed, the factory can prepare materials, develop the pattern, and make the first sample.

After receiving the sample, the buyer should review fit, fabric hand feel, stitching, pocket placement, zipper quality, lining, logo position, labels, and overall construction. If changes are needed, sample revisions may be required before bulk production.

A clear approval process helps reduce production risk. Before bulk production, brands should confirm the final sample, measurement tolerance, fabric standard, trim standard, packaging details, and inspection requirements.
