Long Sleeve Heavyweight Tee Manufacturer: RFQ Guide
By Weavnora · Updated
Direct answer
What buyers need to know
A long sleeve heavyweight tee manufacturer is a cut-and-sew partner that turns 220–300 GSM cotton jersey into long sleeve tees with controlled sleeve length, cuff finish, and post-wash fit. The RFQ has to define sleeve-specific details that a short sleeve brief never covers.
What changes when a heavyweight tee gets long sleeves?
A long sleeve tee is not a short sleeve body with extra fabric. The sleeve is the longest single panel on the garment, so it carries most of the risk on shrinkage, twist, and length consistency. When you brief a long sleeve heavyweight tee manufacturer, the sleeve, cuff, and wash need their own lines in the tech pack.
Weight matters more here as well. A 300 GSM long sleeve drapes and feels very different from a 300 GSM short sleeve because the extra sleeve mass pulls on the shoulder seam. Many brands land between 220 and 260 GSM for long sleeves and keep 280–300 GSM for short sleeve boxy tees, but the right answer depends on your season and handfeel target.
Which fabric weight should you choose?
| GSM band | Typical use | Trade-off |
|---|---|---|
| 220–240 GSM | Layering, transitional season | Lighter drape, less shoulder drag |
| 250–270 GSM | Core streetwear long sleeve | Balanced structure and comfort |
| 280–300 GSM | Statement heavyweight look | Heavier sleeve, stronger shrink control needed |
Compare the options on a finished, washed sample rather than on a fabric swatch. Weight reads differently once a sleeve hangs from the shoulder.
Cuff rib or plain hemmed sleeve?
A 1x1 or 2x2 rib cuff keeps the sleeve end snug and hides small length differences. A plain coverstitched sleeve hem looks cleaner on oversized fits but shows every centimeter of variation. If you choose rib, specify cuff height (for example 6–8 cm), rib GSM matched to the body, and the recovery you expect after wash. If you choose a plain hem, specify hem width and stitch type.
How should sleeve length be graded?
Sleeve length is usually measured from center back neck or from the shoulder point; pick one method and write it on every size. Grade increments should be stated per size, not left to the factory pattern room. For washed programs, ask for sleeve length to be measured after the wash recipe, because garment wash can shorten a long sleeve more than the body.
Buyer QA practice: approve sleeve length on three sizes of the washed sample (smallest, base, largest) before you sign off the size set.

Timing and order planning
Weavnora works to about 7 days for a sample once details are confirmed and about 30 days for bulk after approvals, depending on the project. Long sleeves add fabric consumption per piece, so confirm fabric booking early if you plan multiple colorways inside the 1,000-piece style minimum. Mixed colors and sizes are supported when the assortment is clear at order stage.
Common mistakes on long sleeve programs
- Approving fit on an unwashed sample, then receiving shorter sleeves after wash.
- Using a lighter rib on the cuff than on the collar, so the two recover differently.
- Placing a sleeve print by eye instead of a measured drop from the shoulder seam.
- Forgetting that folded packing size grows, which affects polybag and carton spec.
Reviewing these points first keeps the long sleeve program close to the approved sample when bulk ships.
