Tubular vs Side-Seam for Heavyweight Tee OEM
By Weavnora · Updated
Direct answer
What buyers need to know
Tubular and side-seam are two body constructions for heavyweight cotton tee OEM. Tubular knits the body as a tube with no side seams; side-seam panels are cut and sewn at the sides for cleaner shaping and easier decoration placement. For Weavnora programs on 100% cotton tees at 220–300 GSM, freeze construction before the ~7-day sample after confirmation, approve decoration on that body, then plan the 1,000-piece style MOQ into a ~30-day bulk window (project-dependent) for North America and Europe.

FAQ
**Which construction shapes better for brand fits?**
Side-seam usually supports cleaner shaping and graded side curves. Tubular feels continuous but may limit aggressive silhouette shaping.
**Does construction change decoration planning?**
Yes. Side seams create a clear panel map; tubular needs placement rules for the seamless tube. Approve decoration on the same construction you will bulk.
**What MOQ and lead times apply?**
Style MOQ 1,000 pieces with mixed colors/sizes. Sample ~7 days after confirmation; bulk ~30 days after approvals (project-dependent).
**Who should receive the construction brief?**
Email **postmaster@weavnora.com** with construction choice, GSM target, decoration files, size curve, and NA/EU ship-to notes.

Construction Trade-Offs for Brand Buyers
Choose **side-seam** when the tech pack grades a shaped side curve, when left/right panel balance matters for multi-location decoration, or when you need predictable panel maps for screen print, DTG, embroidery, or special print. Choose **tubular** when the brand story prefers a continuous body with fewer seam lines and you accept tighter placement rules around the seamless tube.
Do not mix constructions inside one style code. A tubular sample cannot authorize a side-seam bulk run, and the reverse is also true. Treat a late construction swap as a new confirmation event before the ~7-day sample clock restarts.
Measurement and Fit Gates
1. Confirm chest, body length, and sleeve against the size chart on the chosen construction.
2. Check side shape on at least the primary size you will open first.
3. Record wash or unfinished direction with the construction choice so shrinkage behavior stays linked to the approved body.
4. Reject samples that meet GSM but fail construction geometry—handfeel alone is not enough.
Decoration Sequencing
Lock construction before artwork placement. Side-seam panels make front/back print windows clearer; tubular bodies need written placement offsets from centerline and hem. Approve decoration on the same 100% cotton GSM base (220–300) and the same tubular or side-seam body planned for the 1,000-piece style MOQ.
