How to Create a Tech Pack for a Clothing Manufacturer

A clothing tech pack is the working document that turns a brand idea into a product a manufacturer can sample and produce. It does not have to be beautiful or complicated. It needs to be clear enough that the factory can understand what to make, what materials to use and what details must be checked before bulk production.

For startup brands, a strong tech pack prevents the most expensive kind of revision: discovering that everyone understood the design differently after the sample has already been made.

What a Clothing Tech Pack Does

A tech pack records the product specification in one place. It normally includes flat sketches, measurements, fabric and trim choices, construction notes, colors, artwork placements, label requirements and packaging instructions. It gives your manufacturer a document to quote from and gives both sides a reference during sample approval and bulk production.

Without a tech pack, a project may still start from photos and messages, but details get lost quickly. “Same as reference” is not a measurable instruction. A tech pack replaces assumptions with information that can be reviewed, sampled and approved.

The Essential Parts of a Tech Pack

Begin With Clear Product Flats

Use a simple front and back flat drawing to show the garment shape. It can be produced in Illustrator, a design app or a clean annotated PDF. The point is not fashion illustration. The point is to show where a pocket begins, whether a shoulder is dropped, what kind of cuff is used and where every decoration sits.

Add callouts to details that cannot be guessed: hood shape, drawcord exit, pocket height, seam positions, distressed panels, double-layer construction or special wash areas. Compare the flat drawing against the product direction shown in the manufacturing process.

Make the Measurement Spec Usable

Measurements are the core of a production-ready tech pack. Include a base size and list each point of measure with a clear definition. For a T-shirt, this may include chest width, body length, shoulder width, sleeve opening, sleeve length and neck opening. For a hoodie, add hood height, hood opening, pocket width, cuff height and bottom rib height.

For a practical method that defines points of measure and tolerances, use our hoodie measurement guide when preparing the specification page.

Use a tolerance where appropriate. Small variations happen in garment production; a sensible tolerance tells the factory what range is acceptable. For an oversized style, write the intended relationship between body, shoulder and sleeve rather than assuming the term means the same thing to every factory.

Specify Fabric and Trims Early

The fabric section should state composition, target GSM, color and finish. If a reference garment is important, describe what you like about it: structured surface, soft brushed interior, dry hand feel, washed appearance or compact rib. A photo helps, but it does not replace the written fabric brief.

The same applies to trims. Specify whether the neck label is woven or printed, whether drawcord tips are metal or dipped, whether zippers are nylon or metal, and what packaging is required. Details such as label position and hangtag attachment should be included before bulk production, not after the final sample is approved.

Use the fabric page to frame the right questions about cotton jersey, French terry, fleece and brushed hoodie fabrics.

Add Artwork Files and Placement Measurements

Artwork should be supplied as editable vector files for logos and text whenever possible. High-resolution raster files can be used for detailed DTG artwork, but the print size and resolution must be adequate. Name each file clearly and place it in the tech pack with a print width, print height and position measurement from a stable garment point such as the high-point shoulder or center front.

State the intended decoration method if it is already known, or ask the manufacturer to recommend one. A small embroidered chest logo, a multi-color DTG illustration and a large screen print need different production preparation. The technology page can help you compare methods before you submit final artwork.

Keep Sample Comments Inside the Same Document

The best tech packs evolve with the sample process. After each sample, add dated comments with photos or marked-up measurements. Write what is approved, what must change and what must not change. This creates a record that protects both the brand and the manufacturer, especially when several people are giving feedback.

Tech Pack Checklist Before You Request a Quote

1. What product is being made, and which size is the base sample?
2. What fabric, GSM and color direction should be used?
3. What are the exact finished measurements and tolerances?
4. Which trims, labels and packaging are required?
5. Where does each logo or graphic go, and what size should it be?
6. Which construction details are required or prohibited?
7. What quantity, target date and sample approval route does the project need?

Final Thoughts

A useful tech pack is a communication tool, not a test of design software skills. Start with the clearest information you have, identify the details that matter most to your brand and improve the document through sampling. The better the information before sampling, the fewer surprises you will have before bulk production.
