A factory can only quote what it can read. What is a tech pack? It is the structured specification document that tells a manufacturer exactly what to make: the sketches, materials, measurements, construction, artwork placement, labels and packaging for one style. Without it, a quote for a fishing shirt is an estimate built on assumptions, and the first sample tests the assumptions rather than the design.
This guide is for brands, especially new ones, preparing to ask a fishing apparel manufacturer for a quote. It explains what a tech pack must include, which fields are specific to fishing shirts, what to do if you do not have one yet, the mistakes that cost sample rounds, and how the pack moves through quote, sample and bulk.
A free six-sheet template is linked at the end. It carries example text only; your fabric, measurements and tolerances replace it.
What Is a Tech Pack, and Why Does a Quote Depend on It?
Techpacker, a tech pack software provider, defines a tech pack as a structured specification document that gives a clothing manufacturer every instruction needed, and lists its core components as a cover page with style information, technical flat sketches, a bill of materials including labels and trims, measurement specifications with a grading chart, construction and stitching notes, a cost sheet and a revision log. White2Label Manufacturing, a garment factory, describes it from the receiving end as the technical pack of information a brand supplies for production, and the blueprint the supplier follows through sampling and manufacturing.
Both sources make the same point about quotes. Techpacker notes that factories need the spec to price accurately, and that without a bill of materials and construction details a quote is only a rough estimate. BOMME STUDIO, a Los Angeles manufacturer, puts it in one sentence: the factory can only execute what is clearly defined.
For a fishing shirt the stakes are higher than for a plain tee, because the features that sell the shirt, such as sun protection, venting, a hood and mask, a sublimated layout and saltwater-safe hardware, are exactly the items a factory cannot guess.
What a Fishing Shirt Tech Pack Must Include
The table follows the six sheets of the downloadable template. The left column is standard tech pack content; the right column is what makes it a fishing shirt.
| Section | Standard content | Fishing-shirt specifics |
|---|---|---|
| Cover and style info | Brand, style name and number, season, contact, revision log | Intended decoration method, colourways and which artwork file applies to each, quantity plan so the factory can explain how its minimum is counted |
| Bill of materials | Every fabric and trim with composition, weight, colour reference and supplier | Main fabric with a UPF requirement and the test evidence expected for that fabric and colour; mesh venting fabric; hood or mask fabric; zipper and snaps rated for saltwater; thread colourfastness |
| Measurements and grading | Numbered points of measure, how each is taken, tolerance, values per size | Collar height for sun coverage, hood height and width, mask height, thumbhole position, sleeve length measured for casting reach |
| Construction and features | Seam types, stitch density, hems, closures | Flatlock or cover-stitch choice for comfort under straps, vent placement, pocket type and position, roll-up sleeve tab, sunglass loop or cleaner, tool loop |
| Artwork placement | Position, file name, size, placement reference, method, colours | Sublimation panels defined against the factory template, logo positions that stay clear of seams, sponsor positions for team versions |
| Labels and packaging | Main label, size label, care and content label, hang tag, bag, carton marks | Any performance claim on a hang tag matched to a test report; labelling content for each destination market |
Two parts deserve care. White2Label stresses setting a tolerance for every measurement, because the tolerance defines the variance that will be accepted in bulk. And BOMME STUDIO's own list of what a tech pack typically includes puts artwork placement and print-method notes alongside measurements and construction, which is where fishing shirt tech packs most often fall short: a mockup shows the design, but not where each panel starts, how large the chest logo is, or which method applies to which position.
For the fabric row, describe the requirement rather than the assumption. Our guide to choosing fabric for custom fishing shirts explains how to turn intended use into a fabric brief, and AATCC's directory of test methods names the test categories, such as colourfastness and dimensional change, that a performance requirement can refer to.
A Simple T-Shirt Tech Pack for Manufacturing: The Minimum That Still Works
Not every style needs forty pages. A basic short-sleeve performance tee can be quoted and sampled from a short pack, as long as the short pack is complete rather than vague. The minimum that still works contains:
- A front and back flat sketch with callouts for every seam and feature.
- A bill of materials naming the fabric by composition, weight and finish requirement, plus thread, labels and bag.
- A measurement sheet with the points of measure, how each is taken, a tolerance for each, and values for at least the base size.
- Construction notes for seams, hems and neck finish.
- Label and packaging instructions, including the content the care label must carry.
- A revision number and date.
What distinguishes this from a spec sheet is everything except item three. Techpacker's warning applies: a spec sheet that covers only measurements is not a tech pack. If the shirt has a pocket, a hood, venting or decoration, the pack grows by one section per feature, not by vagueness.
If You Do Not Have a Tech Pack
Three routes exist, and they map onto the sourcing models described in our guide to OEM, ODM and private label.
Start from a factory style. Under an ODM arrangement the factory already holds the pattern and construction, and your brief shrinks to the changes: fabric, colourways, artwork, labels and any modified features. Ask for the factory's own spec of the base style so your changes are written against it.
Send a reference garment. A physical shirt with annotated changes is a legitimate starting point; BOMME STUDIO, for instance, offers sample development from reference garments through its sample-making service. Pin a note to each change, photograph the garment from front, back and inside, and list the measurements you want kept and those you want altered.
Have the factory write the pack. Many manufacturers will build a tech pack during development. Our 4F services include free design and free templates for exactly this stage. Whoever writes it, Techpacker's point stands: the important part is that one party owns and maintains it, and that you receive the finished pack so the style stays yours to reorder or move.
Common Mistakes
- Renders instead of flats. A presentation render shows the idea; a technical flat with callouts shows the construction. Techpacker notes that a front-view-only sketch leaves the factory without the full picture.
- No tolerances. A measurement without a tolerance cannot be inspected. White2Label makes tolerance per measurement a core requirement.
- No colour standard. "Navy" is not a specification. Name the colour reference and say whether a lab dip or a printed strike-off is required before bulk.
- Artwork without placement. A logo file with no position, size or method invites a guess. Our artwork guide for sublimated fishing jerseys covers files, templates and colour workflow.
- Information scattered across emails. Techpacker argues that fragmentation causes more miscommunication than incomplete specs. Keep one pack, one revision number, and attach the current version to every message.
- A stale revision in circulation. When the collar height changes, raise the revision, update the log on the cover sheet and tell the factory which version supersedes which.
From Tech Pack to Quote, Sample and Bulk
The pack is read four times, by different people, for different purposes.
- Quote. The merchandiser prices the bill of materials, counts operations from the construction notes and checks the quantity plan against minimums. Our MOQ guide explains what the quantity plan should state.
- Sample. The sample room cuts from the measurement sheet and construction notes. What is free, what is quoted and how to evaluate the result are covered in our guide to manufacturer sample policies.
- Pre-production. The approved pre-production sample and the current tech pack revision together become the reference for bulk.
- Inspection. The measurement tolerances, construction notes and label instructions are what the inspector checks against.
A tech pack that works at step four is the one that was precise at step one.
Download the Fishing Shirt Tech Pack Template (Spec Sheet Example)
The fishing shirt tech pack template is a spreadsheet with six sheets that follow the table above:
| Sheet | What it holds | How to fill it |
|---|---|---|
| Cover | Style identity, contact, decoration method, colourways, quantity plan, revision log | Replace the example brand and style; raise the revision line on every change |
| Bill of materials | Rows for body fabric, mesh, hood fabric, thread, zipper, snaps, labels, hang tag, bag | Fill composition, weight, colour reference and the performance evidence expected |
| Measurements | Points of measure for a hooded shirt with a how-to-measure column and a tolerance column | Enter the unit, base size and values; leave grading to be confirmed on the size set |
| Construction and features | Fit, seam type, stitch density, hem, collar, hood, mask, thumbholes, venting, pocket, loops | Choose from the options column and strike what the style does not have |
| Artwork placement | Positions for sublimation panels, chest logo, sleeves, back neck, hood and team rosters | Name the file, size and placement reference for each position |
| Labels and packaging | Main, size and care labels, hang tags, poly bag, size sticker, folding, cartons | Add the label content your destination market requires |
Every cell is example text or a "fill in" marker; there are no factory figures in it. The measurement sheet lists common points of measure for a hooded fishing shirt and leaves the size columns empty, because the values belong to your fit block, not to a template. For the care and content label row, the United States Federal Trade Commission's labelling guidance is an example of what a market requires: fibre content by generic name and percentage, country of origin, and the name or registered identification number of a responsible company. Other markets have their own rules.
Frequently Asked Questions
What is the difference between a tech pack and a spec sheet?
A spec sheet is the measurement page. A tech pack contains the spec sheet plus sketches, bill of materials, construction, artwork, labels, packaging and the revision history. Factories quote from the whole pack, not from the measurements alone.
Who should create the tech pack?
Whoever is responsible for turning the design into a product: a designer, technical designer, product developer or founder. If the factory drafts it during development, ask for the finished file so the specification stays with your brand.
How detailed do measurements need to be?
Every point of measure needs a how-to-measure description, a tolerance and a value for at least the base size. Grading across sizes is confirmed on a size-set sample, but the pack should state which sizes are required.
Can the factory make the tech pack for me?
Often, yes, especially when you start from a factory style or a reference garment. Agree who owns the resulting pack and patterns before development starts.
Send Your Tech Pack to CYCLODRY
