200–400 GSM French terry & fleece, built like flagship streetwear.

GMB Manufacturing builds heavyweight hoodies the way flagship streetwear brands want them produced — boxy, structured, and dense. Our cut-and-sew floor specializes in 320 GSM and 400 GSM French terry and brushed fleece, with reinforced shoulder seams, ribbed cuffs, double-needle hems, and chunky drawcords with metal tipping. Every order is built to your tech pack, not pulled from a blank.
Choose the weight that matches your brand positioning. Lighter weights (200–240 GSM) work for everyday fashion drops. Mid-weights (280 GSM) hit the sweet spot for retail. Heavy (320 GSM) and signature (400 GSM) deliver that boxy, structured drape that premium streetwear customers expect.
Heavyweight hoodies live and die by their construction. We build to a tech pack and obsess over the spec sheet — every hoodie that leaves the floor is inspected against your approved sample.
Combine any decoration method on a single hoodie. Most premium clients pair embroidered chest hits with screen-printed back graphics and woven neck labels.

Production runs start at 50 units per style/colorway. Samples are produced individually before bulk runs.
320 GSM is our heavy retail weight — substantial but still wearable year-round. 400 GSM is the signature streetwear weight, with a dense, structured drape and minimal stretch. Most premium drops choose 400.
