Mock Neck Heavyweight Tee OEM: Collar Build and Fit
By Weavnora · Updated
Direct answer
What buyers need to know
A mock neck heavyweight tee is a 100% cotton tee with a short, upright folded collar instead of a crew neckband. In an OEM program it means controlling collar height, rib structure, neck opening stretch, and wash so the collar stands evenly on every size.
What makes a mock neck harder than a crew neck?
A crew neck lies flat against the body. A mock neck has to stand up, so small changes in rib structure, seam allowance, or wash can make it collapse or flare. For a mock neck heavyweight tee OEM program the collar is the approval point, and everything else follows it.
Collar height and construction
Most mock necks use a doubled rib folded on itself. Write the finished collar height you want, for example 3–4 cm, and say whether it is measured at center front or center back. Then specify:
- Rib type: 1x1 for a smooth face, 2x2 for more texture and grip.
- Rib GSM relative to the body, so a heavy body does not overpower a light collar.
- Seam finish inside the neck: taped, coverstitched, or bound.
- Whether the collar sits straight or tapers slightly toward the back.
Neck opening: the comfort test
A mock neck must pass over the head and then recover. If the opening is too small, customers stretch it and the collar distorts. If it is too large, the collar will not stand. Give a relaxed and a stretched neck opening measurement per size, and ask the factory to check recovery after the wash.
| Choice | Effect on mock neck |
|---|---|
| Taller collar | Stronger look, more risk of folding over |
| Shorter collar | Easier to wear, closer to a crew neck look |
| Heavier rib | Stands better, can feel stiff |
| Lighter rib | Softer, may collapse after wash |
Choose the combination on a washed sample, because the comparison changes after garment dye or enzyme wash.
Body weight and fit
Mock necks pair well with 240–280 GSM jersey in a regular or slightly boxy fit. A very heavy 300 GSM body can make the collar look small; a light body can make it look stiff. Review the full silhouette, not only the collar, before approving.

Wash and dye risks
Garment dye can shrink the rib collar differently from the body because the rib has more stretch. Vintage or acid wash can soften the collar until it no longer stands. Ask the factory to run the exact wash recipe on the first sample and report collar height before and after.
Buyer QA practice: photograph the collar from the side on a form for every sample round, so collar stand is compared on the same angle.
RFQ checklist for a mock neck tee
- Body: 100% cotton, GSM target, color or dye route.
- Collar: finished height, rib type, rib GSM, inside seam finish.
- Neck opening: relaxed and stretched per size.
- Fit: chest, length, shoulder, sleeve per size.
- Wash: recipe and expected handfeel.
- Decoration and labels: avoid heavy neck labels that pull the collar down.
- Order: assortment within the 1,000-piece style MOQ.
Timing
Weavnora plans about 7 days for a sample after details are confirmed and about 30 days for bulk after approvals, project-dependent. Plan one extra sample round for a new collar build; it is cheaper than correcting a collapsed collar in bulk.
