A useful tech pack example is not simply a PDF containing flats, a BOM and a size chart. It is a connected control system: every important feature has a material, measurement or construction rule, an owner and an approval status. Use the annotated overshirt example below to decide whether your document is ready for a first sample.
This article uses a teaching style called OS-2401: a men's regular-fit overshirt in cotton twill with a button front, two chest pockets, a back yoke and adjustable cuffs. The style number and specifications are illustrative, not a customer record or a universal fit recommendation. The point is to show how the fields work together.
If you need the broad list of pages first, start with Cynida's menswear tech pack checklist. This guide takes the narrower next step: reading one example field by field and finding contradictions before the sample room has to find them for you.

How to Read This Tech Pack Example
First, give every field a visible status. A blank cell asks the factory to guess whether the information is missing, unchanged or open for proposal. Use a simple status system throughout the pack:
| Status | Meaning | Buyer action |
|---|---|---|
| Confirmed | The factory should work to this information | Approve any later change in the revision log |
| Factory proposal required | The factory may suggest a workable option | Review the proposed material, method, price and timing |
| TBC before sample | Sampling should not start until this is resolved | Assign an owner and due date |
| Not applicable | The field does not apply to this style | Mark it deliberately instead of leaving it blank |
The useful question is not, “Does this pack have a BOM page?” It is, “Can we trace each important feature from the drawing to the material, method, measurement and approval record?” A polished page can still contain an uncontrolled detail. Spreadsheets are very good at looking certain.
Page 1: Make the Cover Sheet a Control Page
The cover sheet identifies the product and the exact document being reviewed. It should stop an old file, wrong sample size or unnamed colorway from entering the next handoff.
| Field | Example value | Status | Why the factory needs it |
|---|---|---|---|
| Brand / style | Example Brand / OS-2401 | Confirmed | Connects every page, sample and comment to one style |
| Product | Men's regular-fit overshirt | Confirmed | Sets the product and fit direction |
| Season / market | Fall 2027 / United States | Confirmed | Frames delivery, labeling and market review |
| Document version | V1.2, dated August 2, 2026 | Confirmed | Identifies the current source of truth |
| Sample size / range | M / XS–XXL | Confirmed | Separates the fit sample from the intended size run |
| Colorways | Olive and navy | Confirmed | Connects drawings, fabric, thread, buttons and labels by color |
| Planned quantity | 100 pieces total; 50 per color | Factory review required | Allows the factory to check fabric, trim and color-split feasibility |
| Required sample date | Buyer to confirm | TBC before sample | Prevents an assumed calendar from becoming a promise |
Repeat the style number, version and date in the header or footer of every page. A filename such as OS-2401_V1.2_2026-08-02.pdf is more useful than overshirt_final_really-final.pdf, a title that has already lived a full and dangerous life.
Pages 2–3: Make the Flats and Callouts Agree
Show the front and back of the garment, plus internal or enlarged views when the main flats cannot reveal a detail. Number the callouts and connect each number to a written requirement.
For OS-2401, the front flat might show:
| Callout | Visible feature | The note must resolve |
|---|---|---|
| 01 | Two-piece collar and collar stand | Finished shape, topstitch distance and interlining direction |
| 02 | Center-front button placket | Finished width, button count, spacing rule and topstitching |
| 03 | Two chest patch pockets | Finished dimensions, placement reference and corner reinforcement |
| 04 | Adjustable cuff with two buttons | Cuff depth, button spacing and usable adjustment positions |
| 05 | Curved hem with side gussets | Hem shape, turn-up, gusset material and topstitching |
| 06 | Back yoke with center box pleat | Yoke depth, pleat intake and stitch construction |
Do not write “as reference” beside a photograph and assume the visible details have become instructions. The drawing should show what remains, what changes and what the factory must reproduce. Internal construction, pocket bags, interlining and hidden labels may need separate views because a front flat cannot report what it cannot see.
Then cross-check the callout list against the rest of the pack. If callout 04 shows two cuff buttons, the BOM needs the correct button quantity and specification. The construction page needs the attachment and spacing method. The sample comments need a check for function and appearance. One feature, several linked controls.
Page 4: Turn the BOM Into Sourcing Decisions
A bill of materials should describe every material and trim used to make, brand and pack the garment. The exact fields vary by product, but a useful BOM identifies the part, specification, color, source or proposal status, unit and approval reference.
| Ref | Part | Example specification | Color / source | Status before sample |
|---|---|---|---|---|
| A | Shell fabric | 100% cotton twill; target 240 GSM; brushed face; preshrunk direction | Olive and navy; factory proposal | Submit swatches and available test information for approval |
| B | Pocketing | Cotton-polyester plain weave; target lightweight pocketing quality | Tonal; factory proposal | Confirm hand feel and shade before cutting |
| C | Collar/cuff interlining | Woven fusible; weight to support the approved collar shape | White or charcoal by shell shade | Factory proposal required |
| D | Front and cuff buttons | Four-hole resin; 18L front, 16L cuff; matte finish | Tonal; nominated shape | Approve physical trim sample and quantity per garment |
| E | Sewing thread | Polyester core-spun; ticket and color proposed for construction | Tonal | Confirm shade and visible topstitch appearance |
| F | Main, size and care labels | Final artwork, dimensions, fold type and attachment method | Separate artwork files | TBC before sample if branded labels are required on the first sample |
“Soft cotton” is a direction, not a controlled fabric specification. Composition, construction, weight and finish help a factory search. A dated swatch or approved material reference closes the decision. When a material is genuinely open, write Factory proposal required and define what the proposal must achieve rather than filling the cell with confidence-shaped fog.
Check BOM quantities against the drawings. Two cuffs with two usable buttons each may require four attached cuff buttons, plus any approved spare-button requirement. The front placket count must match the flat and placement plan. Label and packaging components belong in the same control system even when they are approved later.

Page 5: Define Each Point of Measure and Its Condition
A measurement table needs more than a point name and a number. It should state the sample size, unit, measuring method, garment condition, target and tolerance. Use a numbered diagram so the pattern maker, buyer and quality team measure the same line.
The values below only demonstrate the document structure. They are not Cynida's standard overshirt measurements or suggested tolerances.
| POM | Base-size M example | Measuring method | Example tolerance |
|---|---|---|---|
| 01 Half chest | 58.0 cm | Buttoned and laid flat; straight across 2.5 cm below the armhole | ±1.0 cm |
| 02 Body length | 72.0 cm | High point shoulder to finished hem, following a straight vertical line | ±1.0 cm |
| 03 Across shoulder | 48.0 cm | Shoulder seam to shoulder seam across the back | ±0.7 cm |
| 04 Sleeve length | 64.0 cm | Shoulder point to finished cuff edge along the sleeve | ±0.7 cm |
| 05 Bottom opening | 57.0 cm | Garment laid flat; straight across the finished hem | ±1.0 cm |
State whether the garment is measured relaxed or stretched, open or fastened, before or after the approved care method. If a washed-garment result matters, keep the before-care and after-care records distinct. A percentage without the specimen condition and measuring method is weak evidence.
Do not grade the full size range by copying one increment into every POM. First approve the base-size fit and the size architecture. Then record the grade rule or finished measurement for each size, with any product-specific checks for pocket placement, collar proportion, sleeve pitch or hem balance.

Pages 6–8: Connect Construction, Branding and Packing to the Pattern
Construction notes translate the flats into operations the pattern and sample teams can follow. For the example overshirt, resolve seam type, seam allowance, topstitch distance, reinforcement, interlining placement, button attachment and pressing direction where each one affects appearance, fit, durability or cost.
| Feature | Construction instruction example | Related control |
|---|---|---|
| Chest pocket | Clean-finished top edge; two parallel topstitch rows; reinforced top corners | Flat callout 03 and pocket POM diagram |
| Front placket | Separate applied placket; finished width recorded; topstitch both edges | Flat callout 02 and button-placement plan |
| Collar | Two-piece collar and stand with approved interlining | BOM refs A and C; collar POMs; physical sample |
| Side seam | Defined seam and finish; side gusset inserted at hem | Flat callout 05 and internal view |
| Cuff | Adjustable two-button construction; button spacing measured from finished edge | Flat callout 04; BOM ref D; sample function check |
Branding needs its own artwork version, finished dimensions, color reference, application method and placement from stable garment points. Packing needs the fold direction, fastening state, individual bag, barcode or sticker position, size assortment and carton-mark requirements that are known at that stage. Mark later decisions as pending; do not let them hide in a chat thread.
The pattern maker should be able to trace every shape-changing note to a drawing or measurement. The sample room should be able to trace every material and trim to the BOM. The buyer should be able to trace every approval to a dated record. That is how separate pages become one production instruction.
The Two Missing Buttons: What a Cross-Field Failure Looks Like
In a published Cynida Oxford shirt development case, the buyer's reference garment had a small button securing each collar point. Cynida's first sample omitted both buttons. The error was ours.
The feature was visible on the reference, but it had not been translated into an unmistakable drawing callout, BOM line and feature checklist. The corrective sample restored the button-down construction. The lasting lesson was not “look harder.” It was to extract each unfamiliar feature before pattern work and close it with a photo, measurement, material approval or written comment.
Use the same cross-field audit on your example:
| Question | Collar-point-button control |
|---|---|
| Is the feature visible and named? | Front flat and enlarged collar view show two collar-point buttons |
| Is the component in the BOM? | Button size, material, color and quantity are listed |
| Is placement defined? | Button and buttonhole positions use stable collar reference points |
| Is construction clear? | Attachment method and buttonhole direction are stated |
| Is approval recorded? | Sample checklist includes appearance, fastening and symmetry |
Quality control starts here, not only at the final inspection table. Final inspection cannot recover a feature that was never defined.
What Must Be Closed Before the First Sample?
A partial pack, reference garment or clear image can begin a feasibility discussion. Before first-sample work starts, however, the factory normally needs enough confirmed information to build one intentional version:
- Current style number, document version and responsible contacts.
- Front, back and required detail views with numbered callouts.
- Base size, key measurements and measuring methods.
- Fabric direction and the status of every important material and trim.
- Construction decisions that change pattern, appearance or price.
- Artwork or branding requirements needed on the sample.
- Target market, quantity direction and required timing.
- A named owner and due date for every open field.
At Cynida, a typical first sample is usually planned for 7–10 days after the style, fabric direction, measurements and key construction details are confirmed. The timing is conditional because unresolved materials or construction are still development work, not invisible calendar time.
To release this exact version to the sample room, summarize its governing files, sample purpose, open decisions and approver in a garment sample request form. The request is the control page; the tech pack remains the detailed product source.
Before bulk, close the final BOM, measurements and tolerances, approved materials, artwork, workmanship, care or testing requirements, packaging, sample comments and current document version. Bulk production is typically planned for 15–30 days after sample approval and material readiness; quantity, complexity and packing can change that timing. The sample-to-bulk control guide explains how those approvals travel into production.
If your pack is still a mix of confirmed and open information, that is not automatically a reason to delay the conversation. It is a reason to label the status clearly. Cynida's menswear sample-development review can use a current tech pack, reference garment or product images to identify the next decisions before sampling.
A Final Pre-Sample Audit
Before sending the file, check that:
- The filename, cover sheet and every page show the same style and version.
- Every important visible feature has a drawing callout.
- Every material, trim, label and packing component appears in the BOM.
- BOM status is explicit: confirmed, proposal required, TBC or not applicable.
- Every POM has a diagram, method, unit, target and product-specific tolerance.
- Construction notes agree with the flats, BOM and measurement pages.
- Colorways connect fabric, thread, buttons, artwork and labels correctly.
- The sample checklist names the high-risk visual and functional details.
- Comments from earlier rounds are consolidated into the current master file.
- Each remaining open item has an owner and a deadline.
The pack does not need ornamental complexity. It needs one controlled answer wherever the factory must make one garment decision.
Frequently Asked Questions
What is included in a tech pack?
A complete apparel tech pack normally includes style identification, technical flats and callouts, a bill of materials, colorways, points of measure, size and grading information, construction notes, artwork and label specifications, packaging instructions, sample comments and revision history. The exact sections depend on the product and development stage.
What is a sample tech pack?
A sample tech pack is an example specification document that shows how product information can be organized for factory use. It may be a blank template, a teaching example or an anonymized completed pack. Treat its measurements, tolerances, materials and compliance fields as examples—not defaults for a different garment.
How to make your own tech pack?
Start with a unique style number and front/back flats. Add numbered construction callouts, a complete BOM, a base-size POM chart with measuring diagrams, color and artwork details, then a dated revision log. Mark every field as confirmed, proposed, pending or not applicable, and ask the factory to review feasibility before sampling.
Send the current version rather than waiting for a mythical perfect file. Include the product, base size and size range, fabric direction, quantity by design and color, target market and timeline so the next reply can resolve decisions instead of starting another guessing round.
