What Is an Apparel Tech Pack?

If you are starting a clothing brand or preparing a new garment for production, you may have heard the term apparel tech pack. But what exactly is it, and why is it so important?

An apparel tech pack is a detailed document that explains how a garment should be made. It gives manufacturers the technical information they need to turn a designer’s idea, sketch, or sample into a finished product.

A good apparel tech pack can include technical drawings, measurements, fabric details, trims, construction details, color information, labels, packaging instructions, and a Bill of Materials (BOM).

Think of a tech pack as a blueprint for a garment. Instead of relying on guesswork or explaining every detail through emails and messages, the manufacturer can use one organized document as a production reference.

In this guide, we will explain what an apparel tech pack is, what it includes, why you need one, and how it helps you work with clothing manufacturers.

What Is an Apparel Tech Pack?

An apparel tech pack is a technical document containing the specifications and instructions required to manufacture a garment correctly.

It translates a fashion designer’s creative idea into clear technical information that a pattern maker, sample room, factory, or garment manufacturer can understand.

For example, a designer may know that they want to create an oversized cotton T-shirt. But a manufacturer needs much more information.

They may need to know:

• What type of cotton should be used?
• What is the fabric weight?
• What should the finished measurements be?
• How oversized should the fit be?
• What type of neckline should the T-shirt have?
• What thread should be used?
• What stitching method is required?
• Where should the logo be placed?
• What are the print or embroidery specifications?
• What labels are required?
• How should the garment be packed?

An apparel tech pack brings these details together in one structured document.

What Is the Purpose of an Apparel Tech Pack?

The main purpose of an apparel tech pack is to communicate exactly how a garment should be manufactured.

Without a detailed tech pack, manufacturers may have to make assumptions about the design. Those assumptions can lead to incorrect samples, poor fit, material changes, production mistakes, and additional costs.

A well-prepared clothing tech pack creates a common reference for everyone involved in product development.

The designer, technical designer, pattern maker, sample maker, and manufacturer can all work from the same information.

An apparel tech pack helps to:

• Communicate design requirements clearly
• Reduce production errors
• Improve sample accuracy
• Control garment measurements
• Specify materials and trims
• Communicate construction details
• Make costing easier
• Speed up manufacturer communication
• Reduce unnecessary revisions
• Maintain consistency between production batches

In simple terms, an apparel tech pack helps turn a design concept into a manufacturable garment.

What Does an Apparel Tech Pack Include?

The exact contents of a tech pack can vary depending on the garment and the manufacturer. However, a professional apparel tech pack normally contains several important sections.

1. Technical Flats

Technical flats are detailed two-dimensional drawings of the garment.

Unlike a fashion illustration, a technical flat focuses on construction rather than appearance. It normally shows the front and back of the garment and may include side views or detail views where necessary.

Technical flats help manufacturers understand the garment’s construction and design features.

For example, a shirt technical flat may show:

• Collar shape
• Sleeve construction
• Cuffs
• Button placement
• Pocket position
• Seam lines
• Hem construction
• Topstitching

A clear technical drawing is one of the most important parts of a fashion tech pack.

2. Bill of Materials (BOM)

The Bill of Materials, commonly called the BOM, lists the materials and components required to make the garment.

Depending on the product, the BOM may include:

• Main fabric
• Lining
• Interlining
• Thread
• Buttons
• Zippers
• Snaps
• Elastic
• Labels
• Hangtags
• Drawcords
• Packaging materials

The BOM can also include supplier information, material codes, colors, quantities, and other specifications.

This gives the manufacturer a clear understanding of what materials are required for production.

3. Measurement Specification

The measurement specification, or spec sheet, defines the garment’s measurements.

Typical measurements may include:

• Chest
• Waist
• Hip
• Body length
• Shoulder width
• Sleeve length
• Neck width
• Armhole
• Cuff opening
• Hem width

Measurements are normally provided for different sizes.

For example:

Measurement	S	M	L	XL
Chest	52 cm	54 cm	56 cm	58 cm
Body Length	68 cm	70 cm	72 cm	74 cm
Shoulder	44 cm	46 cm	48 cm	50 cm

The exact measurements and grading rules depend on the garment and brand’s fit requirements.

4. Point of Measurement (POM)

A Point of Measurement (POM) explains exactly where each measurement should be taken.

This is important because two people can measure the same garment differently if measurement instructions are unclear.

For example, a tech pack may specify:

Chest: Measure straight across the garment, approximately 1 inch below the armhole, then multiply by two.

Clear POM instructions help the manufacturer measure samples consistently.

5. Grade Rules

Grade rules explain how measurements change between sizes.

For example, if the chest measurement increases by 2 inches between sizes, the tech pack should communicate that grading clearly.

Grade rules help ensure that the garment maintains the intended fit across the entire size range.

6. Fabric Specifications

The fabric section explains exactly what material should be used.

It can include:

• Fiber composition
• Fabric construction
• Fabric weight
• Fabric width
• Fabric finish
• Stretch percentage
• Color
• Shrinkage requirements
• Performance requirements

For example:

Fabric: 100% Cotton Jersey
Weight: 220 GSM
Finish: Enzyme Washed

These specifications help prevent the manufacturer from substituting an unsuitable fabric.

7. Color Specifications

A professional garment tech pack should clearly communicate the colors required for the product.

This may include:

• Main garment color
• Contrast color
• Thread color
• Trim colors
• Print colors
• Embroidery colors

Brands may use standardized color references, such as Pantone codes, when precise color matching is important.

8. Garment Construction Details

Construction details explain how different parts of the garment should be assembled.

This section may specify:

• Seam types
• Stitch types
• Seam allowances
• Stitch density
• Topstitching
• Hem construction
• Binding
• Pocket construction
• Collar attachment
• Sleeve attachment

Construction details are particularly important when a garment contains complex design features.

9. Artwork and Branding Details

If the garment includes a print, embroidery, patch, applique, or other branding element, the tech pack should explain its specifications.

This can include:

• Artwork
• Placement
• Dimensions
• Technique
• Colors
• Thread specifications
• Print method
• Embroidery details

For example, instead of simply saying “logo on chest,” a tech pack can specify the exact placement and finished dimensions.

10. Label and Packaging Information

Labels and packaging are also part of the product specification.

An apparel tech pack may include:

• Main label
• Size label
• Care label
• Country-of-origin label
• Hangtag
• Polybag
• Folding instructions
• Carton information

Including these details helps ensure the finished garment is prepared correctly for delivery.

Apparel Tech Pack vs. Fashion Design Sketch

An apparel tech pack is not the same as a fashion sketch.

A fashion sketch communicates the creative appearance of a garment. It may show the silhouette, styling, colors, and overall aesthetic.

A tech pack goes much further.

It communicates the technical information needed to manufacture that design.

For example:

Fashion sketch:
“This is what the garment should look like.”

Apparel tech pack:
“This is exactly how the garment should be made.”

Both are valuable, but they serve different purposes.

Why Do Clothing Brands Need an Apparel Tech Pack?

A professional tech pack for clothing can save a brand significant time and money during product development.

1. It Reduces Miscommunication

A written specification is much clearer than relying on verbal explanations.

Instead of sending multiple messages to a manufacturer, the brand can provide one organized document.

2. It Improves Sample Accuracy

Manufacturers can use the tech pack as a reference when creating the first sample.

This increases the chance that the sample will match the intended design.

3. It Reduces Production Errors

Clear information about measurements, fabrics, trims, construction, and artwork helps reduce mistakes during manufacturing.

4. It Makes Costing Easier

Manufacturers need to understand the materials and construction of a garment before they can accurately estimate production costs.

A detailed tech pack provides the information needed for better costing.

5. It Makes Manufacturer Communication Easier

If you work with manufacturers in different countries or time zones, communication can become difficult.

A detailed tech pack creates a common technical reference that everyone can follow.

6. It Helps Maintain Consistency

Once a product enters bulk production, the tech pack can continue to act as a production reference.

This is especially useful when a brand works with different factories or produces the same product over multiple seasons.

Who Uses an Apparel Tech Pack?

An apparel tech pack can be used by almost everyone involved in the technical development and manufacturing of a garment.

This may include:

• Fashion designers
• Clothing brands
• Technical designers
• Product developers
• Pattern makers
• Sample makers
• Garment manufacturers
• Factories
• Quality control teams
• Sourcing teams

For a growing fashion brand, the tech pack becomes an important communication tool between the creative and manufacturing sides of the business.

When Should You Create an Apparel Tech Pack?

An apparel tech pack should generally be created once the design concept is sufficiently developed and before the product moves into serious sampling and production.

A common workflow looks like this:

Design concept → Technical drawing → Tech pack → Pattern → Sample → Fit corrections → Final tech pack → Production

The tech pack may be updated several times during product development.

For example, after reviewing a sample, the brand may change:

• Body measurements
• Sleeve length
• Fabric
• Stitching
• Trim specifications
• Print placement
• Construction details

The tech pack should be updated so that the latest approved specifications are clearly documented.

What Is the Difference Between an Apparel Tech Pack and a Tech Pack Template?

An apparel tech pack template is a reusable structure used to create tech packs.

It may contain sections such as:

• Cover page
• Technical flats
• BOM
• Measurement chart
• POM
• Construction details
• Fabric information
• Color information
• Artwork
• Labels
• Packaging
• Revision history

A template can save time because the brand does not need to create the structure from scratch for every product.

However, simply downloading a tech pack template does not mean the garment is ready for manufacturing.

The template needs to be filled with accurate product-specific information.

What Makes a Good Apparel Tech Pack?

A good apparel tech pack should be clear, accurate, complete, and easy to use.

It should answer the manufacturer’s important questions before production begins.

A strong tech pack should have:

Clear technical drawings

The manufacturer should be able to understand the garment’s construction from the drawings.

Accurate measurements

Measurements should be realistic, consistent, and clearly defined.

Complete material information

Fabrics, trims, labels, and other components should be specified.

Clear construction instructions

Important sewing and construction requirements should not be left to guesswork.

Proper artwork specifications

Prints, embroidery, logos, and other graphics should have clear dimensions and placement information.

Revision control

The document should identify the latest version so that the manufacturer does not accidentally work from an outdated specification.

Common Mistakes in Apparel Tech Packs

Even experienced brands can make mistakes when creating technical documentation.

Some common problems include:

Using vague instructions

Instructions such as “use good quality fabric” are not specific enough.

The manufacturer needs measurable specifications.

Missing measurements

A technical drawing alone usually does not provide enough information for accurate production.

Incorrect measurement points

If the POM instructions are unclear, the brand and manufacturer may measure the garment differently.

Missing BOM information

Leaving out trims, labels, thread, or other components can create problems during sampling or production.

Not updating the tech pack

If changes are made during sampling but the tech pack is not updated, the factory may use outdated specifications.

Overcomplicating the document

A tech pack should be detailed, but it should also be organized and easy to understand.

The goal is clarity, not unnecessary complexity.

How Much Does an Apparel Tech Pack Cost?

The cost of an apparel tech pack can vary depending on the garment and the amount of technical detail required.

A simple T-shirt may require fewer specifications than a complex jacket with multiple pockets, zippers, linings, trims, and construction details.

Factors that can affect the cost include:

• Garment complexity
• Number of views and technical drawings
• Number of colorways
• Number of sizes
• Artwork requirements
• Measurement specifications
• BOM complexity
• Construction details
• Number of revisions
• Whether the tech pack is created from a sketch, reference sample, or existing garment

For brands, it is useful to view a tech pack as a product-development investment, rather than simply another design expense.

Can You Create an Apparel Tech Pack Yourself?

Yes. A brand can create its own apparel tech pack if it has the necessary technical knowledge and software.

However, creating a professional fashion tech pack requires more than putting a sketch and measurements into a PDF.

You need to understand areas such as:

• Garment construction
• Pattern measurements
• Fabric specifications
• Size grading
• Sewing terminology
• Technical drawing
• BOM development
• POM definitions
• Manufacturing requirements

For brands without in-house technical design expertise, working with a professional tech pack designer or tech pack service can make the process easier.
