Tech Pack Checklist for Heavyweight T-Shirt OEM

What belongs in a tech pack before heavyweight tee sampling?

A tech pack for heavyweight T-shirt OEM is the single buyer document that names the garment, fabric, construction, measurements, dye or wash direction, decoration, labeling, and quality gates before a factory builds a production-representative sample. Incomplete packs force guesswork; complete packs make the ~7-day sample after confirmation meaningful and protect the later ~30-day bulk plan.

Confirmed program framework

Weavnora OEM programs cover 100% cotton heavyweight or washed T-shirts (hoodies and casualwear when in program scope). Fabric weight is a buyer-selected target within 220–300 GSM. Decoration includes screen printing, DTG, embroidery, or special printing. Style MOQ is 1,000 pieces per style with mixed colors and mixed sizes supported. Planning targets: ~7-day sample after confirmed tech-pack details; ~30-day bulk (project-dependent). Markets: North America and Europe.

Seven control steps for a complete OEM tech pack

01 Freeze style identity and end use

List style name/code, silhouette (classic, oversized, etc.), gender or fit family, and target market (NA/EU). State whether the commercial product is unfinished, washed, or garment-dyed so every later page of the pack points to one identity.

02 Specify fabric and construction, not only "heavy cotton"

Write 100% cotton and the buyer-selected GSM within 220–300. Add fabric construction notes you care about (jersey density direction, handfeel reference), neckband type if critical, stitch types, and any rib or binding callouts. Vague "premium heavyweight" language is not enough to start a controlled sample.

03 Attach a full measurement chart and how points are measured

Include chest, body length, shoulder, sleeve length, and any brand-critical points, with tolerance and measurement method. Name the sample size used for first approval. If the tee will ship washed or garment-dyed, state whether chart values apply before finish, after finish, or both.

04 Document dye, wash, and shade standards### 05 Detail decoration as a production page, not a mood board

For screen print, DTG, embroidery, or special printing: artwork file type, print/embroidery locations, size on garment, colorways, and any special process notes. Placement should reference the same silhouette and GSM base that will be sampled.

06 Add labels, packaging, and compliance hooks for NA/EU

List care label content, brand label, hangtag, polybag/carton marks, and any country-of-origin or fiber-content statements your markets require, so the sample can carry the correct label set for buyer review.

07 Define approval gates and the sample-to-bulk path

State what the first sample must clear (fit, GSM feel, shade/wash, decoration, labels). The ~7-day sample clock starts only after these pack items are agreed. Bulk release (~30 days, project-dependent) should reference the approved sample version, including color/size mix within the 1,000-piece style MOQ.

Buyer takeaway

A heavyweight tee OEM tech pack is a control document: GSM, cotton base, measurements, dye/wash, decoration, labels, and approval gates in one place. When those items are confirmed, sampling is reviewable and bulk planning stays tied to what you actually approved.

Next step

Send your draft tech pack (GSM target, measurement chart, dye/wash, decoration, and color/size mix) to postmaster@weavnora.com for a Weavnora sample-ready review before you lock the first production sample.

Say piece-dyed fabric vs garment dye if relevant, plus wash direction (or "no wash"). Attach shade references (Pantone, physical swatch, or prior bulk standard) and a short note on acceptable shade band. Color and wash belong in the pack before mixed-color planning against the 1,000/style MOQ.
