What buyers should compare
Compare finished fabric weight, composition, fit, decoration compatibility, MOQ, sample lead time, bulk lead time, private-label support, inspection checkpoints and shipping plan before approving an OEM supplier.
Define heavyweight for the target market
Heavyweight T-shirts commonly begin around 220gsm, while 230–260gsm supports premium blanks and streetwear. Fabrics around 280–320gsm create a more structured silhouette but increase heat, shipping weight and decoration considerations.
Match GSM to silhouette
A higher GSM does not automatically create a good oversized fit. Buyers must approve shoulder drop, half-chest, body length, sleeve width, collar rib and fabric drape together. A boxy fit usually balances extra width with controlled body length.
Select cotton and surface finish
Combed cotton can provide a cleaner surface for printing. Compact or dense jersey supports structure, while garment wash can soften the handfeel and create vintage color. Confirm actual composition, finished GSM, shrinkage and wash recipe on the approved sample.
Check decoration compatibility
Screen print and puff print work well on many heavyweight jerseys when ink deposit and curing are controlled. DTG results depend on pretreatment and surface consistency. Embroidery should use suitable backing and stitch density to avoid distortion.
Control collar and shrinkage
The collar is a visible quality signal on heavyweight T-shirts. Check rib composition, width, stretch recovery, neckline shape and seam attachment after washing. Measure length, chest, shoulder and sleeve before and after the agreed wash test.
Prepare repeat orders
Archive the approved fabric, color or wash standard, measurement chart, artwork positions, labels, packaging and inspection tolerances. Repeat orders should reference the same approved specification rather than relying on a product name alone.

Buyer questions
What GSM is considered a heavyweight T-shirt?
Many buyers treat 220gsm and above as heavyweight, with 230–260gsm common for premium blanks and 280gsm-plus used for highly structured or specialty styles.
Is a heavier T-shirt always better?
No. The right GSM depends on climate, fit, decoration, price point and shipping cost. Fabric construction and finishing matter as much as weight.
What should be tested before bulk production?
Confirm finished GSM, composition, shrinkage, spirality, collar recovery, color or wash standard, measurements and decoration durability on the approved sample.
