Complete Guide to Tech Packs

A tech pack is the structured document a fashion brand sends to a manufacturer to explain exactly what needs to be made, from sketches and measurements to materials, construction notes, and packaging details.

Key takeaways

What matters before you keep reading

  1. 01

    A tech pack turns design intent into structured production documentation.

  2. 02

    The strongest tech packs reduce clarification loops by making measurements, materials, and construction decisions explicit before sampling.

  3. 03

    Small fashion teams benefit most when the tech pack workflow stays consistent from first draft to PDF export.

If you are preparing a garment for sampling or production, a tech pack is the document that turns design intent into instructions a manufacturer can actually follow without guessing.

Visual direction helps frame the garment, but the handoff still needs specs, materials, and construction detail in one current pack.

What a tech pack actually does

A tech pack answers the factory's next operational question before the email gets sent. It tells the manufacturer what the garment is, how it should look, how it should be measured, what materials belong in it, and which details are still open.

A sketch or moodboard can start the conversation. A tech pack is what makes the conversation executable.

If the manufacturer still needs three different files and a Slack thread to understand the garment, the pack is not doing its job yet.

    Design concept

    Sets what the pack needs to explain.

  2. 02

    Step 02

    References

    Makes the direction reviewable.

  3. 03

    Step 03

    Draft

    Brings specs into one working file.

  4. 04

    Step 04

    Review

    Closes handoff gaps before export.

  5. 05

    Step 05

    Export

    Creates the version the factory should follow.

  6. 06

    Step 06

    Sampling

    Keeps clarification tied to the current pack.

The pack becomes more useful as the workflow moves from concept alignment into review, export, and factory clarification.

In practice

What changes when the pack stops living in five files

When measurements, BOM details, and version status live in one current workflow, the next revision starts from the latest decision instead of a factory scavenger hunt.

Where a tech pack fits in the workflow

A tech pack sits between concept work and manufacturer execution. It usually starts once the team has a clear garment direction, then becomes more detailed before costing, sampling, and production handoff.

The exact level of detail changes by stage, but the job stays the same: reduce interpretation risk before the garment leaves your hands.

A manufacturer-ready pack works when visuals, specs, trims, and handoff materials stay organized as one current package.

Common mistake

What usually breaks the handoff

These are the ordinary gaps that turn a straightforward sample round into avoidable follow-up.

Sending only sketches and loose notes

A factory can react to silhouette, but it still has to guess the spec, BOM, and construction rules.

Letting files drift out of sync

When sketches, materials, and revision notes live in different places, nobody can prove which version is current.

Leaving materials or grading status implicit

If the team never says what is final, the manufacturer has to pause or improvise on the next sample.

What a complete tech pack usually includes

A usable tech pack usually includes the same core sections, even if the amount of detail grows over time.

SectionWhat it answersWhat breaks when it is missing
Garment overview and flatsWhat the product is and what silhouette is intendedThe factory starts with the wrong visual frame
Measurements and grading statusHow the garment should be measured and whether size logic is already definedFit reviews start with avoidable questions
Materials and BOMWhat needs to be sourced and assembledSubstitutions or delays show up early
Construction notesHow details should actually be builtSample rounds drift on seams, finishes, and trims
Packaging and handoff notesWhat is final, what is pending, and what file is currentThe team wastes time on version and status confusion

When a lighter pack is enough and when it is not

An early concept review or first costing conversation can use a lighter version of the pack. That does not mean the final handoff can stay light.

Before you ask a manufacturer to quote, sample, or prepare production details, the pack should clearly separate:

  • what is final
  • what is still being decided
  • what the factory should follow exactly

Manufacturer requirements vary, but the goal is not to predict every factory preference in advance. The goal is to make intentional decisions explicit and mark the open ones honestly.

Where software helps

Manual documents can work, especially early on. The problem appears once the pack becomes a moving target across multiple files and revisions.

That is where tech pack software helps. A structured workflow makes it easier to keep measurements, BOM details, comments, and exports in one current system instead of rebuilding the handoff every time the garment changes.

If you want the practical checklist first, go to the manufacturer-ready checklist. If you already know the workflow pain, go directly to Alignes.
