Stop Leaving Your Garment Production to Chance. Build Industrial-Grade Tech Packs That Factories Actually Understand.

A drawing is not a blueprint. Our tech pack design services translate your creative vision into hard manufacturing data, covering Bill of Materials (BOM), Points of Measure (POM), and exact construction tolerances so your bulk run is flawless.

Most fashion founders send a basic sketch to an overseas factory and hope for the best. That is exactly how you end up with inconsistent sizing, the wrong zippers, and thousands of dollars in ruined inventory. Factory operators do not guess; they execute exactly what is on the page. We provide tech pack design services that eliminate the guesswork. From technical flats to strict grading rules, we engineer the document that dictates your entire production line.

Why a Basic Sketch Will Destroy Your Bulk Production Run

You have a beautiful design. You send it to a manufacturer. When the physical sample arrives six weeks later, the shoulder drop is wrong, the fabric drapes terribly, and they used a cheap zipper instead of the heavy-duty metal one you wanted.

This happens when you rely on an illustration instead of a garment specification sheet.

A factory floor does not operate on aesthetics. A sewing operator operates on stitch tension, seam allowances, and exact measurements. When you lack a professional clothing tech pack, you force the factory to make blind decisions on your behalf. As an experienced apparel technical design facility, we stop the bleeding before it starts. We map out the exact industrial math needed to execute your garment perfectly, ensuring that any factory in the world can build it right the first time.

What Our Tech Pack Design Services Include

We do not just draw clothes. We build the exact technical parameters required for mass production. Every aspect of the following is meticulously documented to protect your investment.

Technical Flats & CAD Sketches

A front and back drawing is useless if the factory cannot see the interior construction. We draft flat, 2D technical sketches (CADs) that show exact seam placements, darting, topstitching, and hidden hardware.

Detailed Bill of Materials (BOM)

If you do not specify the exact thread weight, the factory will use whatever is cheapest. Our BOM outlines every single physical component of the garment: main fabric GSM, lining material, zipper gauge, button types, and specific label placements.

Points of Measure (POM) & Specs

A medium shirt means nothing without math. We build a comprehensive POM sheet that dictates the exact measurement for the chest, sleeve length, sweep, and collar drop. We establish strict tolerance limits so the factory knows exactly what is acceptable.

Construction & Stitch Callouts

How a piece is sewn determines how long it lasts. We specify the exact stitch type (e.g., flatlock, overlock, single needle) and the Seams Per Inch (SPI). This guarantees your activewear stretches correctly and your heavy denim does not unravel.

Size Grading Rules

Your large size cannot just be a blown-up version of your small. We establish mathematical grading rules across your entire size run (XS to XXL). This ensures the garment proportions remain perfect regardless of the buyer's body type.

Colorways & Pantone Mapping

"Navy blue" is not a manufacturing color. We map your exact visual identity using industry-standard Pantone TCX or TPX codes. This ensures your fabric dyeing and custom embroidery match your brand guidelines perfectly.

The Danger of Buying Cheap Tech Packs from Freelancers

There is a major risk in buying a $50 tech pack from a freelance marketplace: the person drawing it has likely never actually sewn a garment.

They deliver a document that looks professional but contains impossible construction methods. They suggest fabrics that cannot be sewn with the specified stitch type. When the factory tries to build it, the machine jams or the fabric puckers.

Our tech pack manufacturer team works directly on a live factory floor. We know what machines are required to execute specific seams. We know how different GSM weights drape. When we hand you a technical document, it is not just a pretty drawing,it is an executable manufacturing blueprint tested by real production managers.

Whether you’re outfitting a competition team, launching a branded gi line, or testing a new weave weight before committing to bulk, we work as your direct production partner. Free global shipping on all sample orders. No intermediaries. No markups. Fixed 21-day lead times from sample sign-off to delivery. Your spec. Your sample. Your academy.

Our Apparel Technical Design Process

Design Review & Concept Handover

You bring us your sketches, reference photos, or physical samples. We hold a technical review to understand the exact fit, function, and target retail price of the garment.

Measurement & Material Mapping

We establish the base size measurements (the POM) and list every raw material required (the BOM). If you need help choosing fabrics, our sourcing team steps in to provide exact material recommendations.

Why Work With Us Instead of Your Current Supplier
Drafting the Technical Flats

Our technical designers translate your creative concept into 2D industrial CADs. We map out the front, back, interior, and any specialized detail views needed for complex pockets or hardware.

Final Document Compilation

We compile the flats, the math, the colorways, and the grading rules into one centralized PDF. You now have a proprietary asset that you can take to any factory on earth.

I have build a hand full of entrepreneurial businesses, but recently made my first venture into the sportswear sector, and decided to work with Rijiz as my first clothing manufacturer. They did an incredible job bringing my flat sketches to life, and working with me throughout the iterative design process, making small tweaks and suggestions as we moved towards the final product. Their communication was good via email, and they were supportive throughout the process, even checking in with me periodically to ask how things were going. The only hiccups were a last minute increase in the cost per unit of the product, and a slightly longer than expected lead time, but my order quantity was very small, so these problems make sense. I'm sure larger order with them take priority. Overall, they are a great company that I will continue to work with as this business grows, and I would highly recommend them!

Common Questions About Tech Pack Services

You do not need to be an artist. We can start from a rough sketch, a Pinterest mood board, or a physical garment that you want to modify. We handle the technical translation.

For a standard garment, the initial technical flats and POM sheets are usually delivered within 7 to 10 business days, depending on complexity and revision rounds.

Yes. Even a "basic" t-shirt requires specific GSM weights, exact neck ribbing measurements, and hem tolerances. Without a tech pack, the factory will just use their default blank, which defeats the purpose of custom manufacturing.

Absolutely. While we are a full-scale manufacturer and would love to build your bulk run, you own the final PDF. It is an industry-standard document accepted by any professional factory globally.

A tech pack is the instruction manual; the pattern is the physical template. We build the tech pack first to define the rules, and then our pattern makers use it to cut the exact shapes for sampling.

Every day you delay locking down your technical specifications is a day you risk expensive manufacturing errors, inconsistent sizing, and delayed launches.
