Every successful garment starts with a clear plan—and that plan is called a tech pack. Whether you’re launching a new collection or scaling production, the tech pack is the universal language between fashion designers and manufacturers.
A tech pack (technical package) is a detailed document that outlines every specification of a garment, including measurements, materials, construction, trims, and labeling, enabling manufacturers to accurately produce the design.
At Xzapparel, we rely on well-prepared tech packs to speed up sampling, reduce errors, and improve first-hit success rates.
What is included in a tech pack?
A complete tech pack contains everything needed to turn your concept into a production-ready sample.
It should clearly communicate your design vision, garment structure, fabric specs, and branding to your manufacturer.
Key Components of a Tech Pack
- Flat sketches (front, back, side views)
- Measurement chart (POMs) for each size
- Fabric and material specs (type, weight, content)
- Stitching and construction details
- Labeling and trim placement
- Colorways and artwork placement
- Packaging instructions
We often help clients build their first tech pack from a physical sample or design sketch.
Why is a tech pack important?
Clear communication saves time and money.
A tech pack ensures everyone on the production team—pattern makers, sewers, and QC staff—understand your expectations.
Benefits of a Tech Pack
- Faster and more accurate samples
- Lower risk of misunderstandings
- Easier cost estimation and fabric planning
- Consistency across reorders or factories
Without a tech pack, you risk delays, extra revisions, or expensive errors.
What format should a tech pack be in?
Most factories accept PDF or Excel-based tech packs.
Some designers use Adobe Illustrator for sketches and combine files into a single ZIP or cloud link.
Best Practice
- Organize by style code or name
- Use clear file naming (e.g.
SS25-DR001-TechPack.pdf) - Use shared folders (Google Drive, Dropbox)
We accept all common formats and often convert them into internal production layouts.
Can I build a tech pack without a fashion background?
Absolutely—with the right guidance.
Many first-time founders use templates or hire freelance technical designers to translate their ideas into specs.
How We Support
- Tech pack templates for common silhouettes
- Video calls to explain sample feedback
- Help filling in missing data (like GSM or thread type)
Even a basic tech pack improves communication by 80% over informal briefs.
What are the most common tech pack mistakes?
Even experienced brands sometimes miss key data.
Missing measurements, unclear fabric names, or lack of labeling specs often cause costly delays.
Common Issues
- Conflicting measurements between views and charts
- Generic fabric terms like “cotton” with no GSM
- No seam or hem details
- Missing label graphics or placement instructions
We review every tech pack for consistency before confirming sampling timelines.
How many tech packs do I need?
One per style—no exceptions.
Every color, fit variation, or fabric change should be reflected in its own versioned tech pack or update.
Example Breakdown
- DR001 (Wrap Dress – Modal) = v1.0
- DR001B (Wrap Dress – Rayon) = v1.1
- DR002 (Tiered Maxi – Viscose) = new style
This helps maintain tracking across sampling, revisions, and production.
Can tech packs be used for pricing?
Yes, it’s how manufacturers quote.
Tech packs allow us to estimate fabric yield, labor time, accessory cost, and packaging—resulting in an accurate unit price.
What We Analyze
- Stitch complexity (flatlock vs. overlock)
- Fabric usage per size
- Trim types (metal vs. plastic zip)
- Print complexity and placement
Well-prepared tech packs speed up quotation by days.
Conclusion
A tech pack is the foundation of professional apparel production. It minimizes risk, accelerates timelines, and makes scaling possible. At Xzapparel, we encourage every brand—new or seasoned—to invest in a strong tech pack strategy.
