Your tech pack for fitness products is the document that tells a factory exactly what to make: materials, measurements, stitching, hardware, logo placement and packaging, with drawings and tolerances for each.
This guide is for brands preparing their first OEM product or tightening the specs on an existing one. It covers what to include and the details that matter most for belts, straps, sleeves and bands.
It also lists the mistakes that cause extra sample rounds, so your first prototype lands closer to the product you have in mind.
What Is a Tech Pack?
A tech pack is a set of pages that describes a product so completely that a factory can sample and produce it without guessing. Fashion brands have used them for decades, and the same idea works well for lifting gear.
A product specification sheet is a shorter version, often one or two pages listing materials, sizes and branding. Many factories, Oath and Oak included, turn a buyer’s sketch or reference into this kind of sheet before sampling.
The difference is depth. A full tech pack adds drawings, stitch details, tolerances, labeling rules and revision history, which matter most for new designs and long-running products.
What Should a Tech Pack Include?
Most tech packs share the same core pages. The table below lists them and what each one tells the factory.
| Section | What It Covers |
|---|---|
| Overview | Product name, style number, category, target customer and sample size |
| Technical drawings | Front, back and detail views with key features marked |
| Bill of materials | Every material, trim, thread, label and hardware item with color references |
| Measurements | Points of measure for each size, with allowed tolerances |
| Construction | Seam types, stitch types, reinforcement and finishing steps |
| Artwork | Logo files, Pantone colors, method, size and exact placement |
| Labels and packaging | Care and size labels, hang tags, polybags, boxes, barcodes and cartons |
| Quality notes | What will be inspected and what counts as a defect |
A revision log on the first page records each change and its date. When a factory and a brand both work from the latest version, sample rounds stay short.
Which Details Matter Most for Fitness Accessories?
Lifting gear carries load, so every tech pack for fitness products needs details that apparel packs often skip.
Load Points
Mark every point that carries weight, such as strap loops, buckle tabs and D-rings, with the stitch pattern.
Material Thickness
State leather and neoprene thickness in millimeters, with the face fabric or finish you expect.
Hardware
Specify buckle, lever, hook or chain type, size, finish and any engraving on each metal part.
Sizing and Levels
Include the size chart for sleeves and belts, or the resistance levels and colors for bands.
How Detailed Should Measurements Be?
Every dimension a customer would notice belongs in the measurement table: length, width, thickness, hole spacing, loop size and seam allowance. Give each one a tolerance, such as plus or minus a few millimeters.
For sized products, grade the measurements across every size rather than listing only the sample size. A graded table stops the factory from guessing how a medium becomes an extra large.
How Should Drawings Be Prepared?
Drawings do not need to be artistic. Clean line views from the front, back and side, with arrows pointing to each feature, tell a factory more than a styled product photo.
Add close-up views for anything small or unusual, such as a stitch box at a strap loop, the shape of a lever plate or the position of a woven label. Number each callout and match the numbers to the notes in your construction table.
Where you have a reference product, photograph it beside a ruler and mark what should change. Pointing to a real example removes most of the doubt that words alone leave behind.
What Should You Check Before Sending a Tech Pack?
- Every material and trim has a color reference
- Each measurement has a tolerance
- Load points and stitch patterns are marked on a drawing
- Logo files are vector, with size and placement
- Packaging, barcodes and carton marks are described
- The revision number and date are on the first page
A simple tech pack template that covers these points is enough for most accessories. Spreadsheets and slide decks both work, as long as the drawings are clear and every page shows the same version number.
How Does a Complete Pack Change Your Factory Order?
A complete pack shortens development. The factory can quote accurately, source the right materials and build a first sample close to your intent, which often saves a revision round.
You do not need a full pack to begin, though. At Oath and Oak, a sketch, photo or reference product is enough to start, and our team turns it into a spec sheet for your review before the first prototype.
If you have a pack already, send it with your quote request, even if parts are incomplete. Gaps are easier to fill once the factory sees your intent.
Keep the approved pack with the golden sample. Together they become the reference for every bulk lot and every repeat order. Our product development page explains how each sample stage uses them.
Which Tech Pack Mistakes Cause Extra Samples?
Photos Without Measurements
A photo shows the look but not the size, so the first sample becomes a guess at your intent.
Missing Tolerances
Without allowed variation, every small difference becomes a debate during inspection.
Raster Logo Files
Low-resolution images blur when scaled, so embroidery and engraving lose fine details.
Skipping the Packaging Page
Without box sizes and barcode rules, packing is planned late and can delay a finished order.
Several Versions in Circulation
Old files sent by email lead to samples built to the wrong version and wasted rounds.
What Else Do Buyers Ask About Writing Their Tech Pack for Fitness Products?
Do we need a designer to make a tech pack?
Not always. Simple accessories can be specified by a brand owner with clear drawings and measurements. Complex or sized products benefit from a technical designer who knows construction and grading.
Which software should we use?
Spreadsheets, presentation files and specialist product software all work. What matters is clear drawings, complete tables and one current version that everyone on your team and the factory side uses.
Does the factory keep our tech pack confidential?
A responsible factory uses your pack only for your project. Ask your manufacturer about confidentiality before sharing detailed files, and request a signed agreement if your design needs that extra protection.
Should the tech pack include target cost?
Many brands add a target cost or price band, which helps the factory suggest materials and methods that fit. It is optional, but it often speeds up the first quote.
How often should a tech pack be updated?
Update it whenever a sample round changes something, and record the change in the revision log. The final approved version should match the golden sample exactly.
