01
Product Direction
The process starts by defining what the product is, who it is for, and how it should perform. For fitness clothing, that means the product type, training use, target customer, and fit goal.

From design to factory-ready tech packs
Before a fitness clothing manufacturer can sample a product properly, the product needs to be clear. This process turns an idea, reference image, or early sketch into a factory-ready product file that explains the fit, fabric, construction, branding, sampling direction, and production requirements.
02
Design Development
With direction set, the idea becomes a visible design: front, back, and side views, seam placement, paneling, waistband structure, straps, closures, and branding.
03
Fabric and Trim Direction
Fabric decides how activewear fits, stretches, recovers, and performs. This step sets stretch, compression, GSM, opacity, and whether to use cut-and-sew, rib, brushed, or seamless materials.
04
Measurement Planning
A factory cannot build a reliable sample from images alone. Measurement planning sets key dimensions, size range, fit notes, and grading before sampling begins.
Waistband height28.0 cm
Hip, relaxed44.5 cm
Inseam66.0 cm
Grade, per size±2.0 cm
05
Construction Details
Construction details explain how the garment is built: stitching, seams, waistband, lining, hems, closures, pockets, support zones, and finishing.
06
Branding and Packaging Details
Branding and packaging are planned before production, not added last minute. This step sets logo placements, labels, care labels, heat transfers, patches, hang tags, and polybags.
07
Factory-Ready Tech Pack
The factory-ready tech pack pulls everything into one file: sketches, measurements, grading, materials, trims, stitching, construction, labels, branding, and packaging.

08
Sampling Preparation
Before sampling, the factory needs the final files, fabric and trim details, branding, and measurements, so the first sample is not built on incomplete instructions.
09
Revisions and Approval
The first sample is reviewed for fit, fabric, construction, comfort, measurements, and branding. Changes are documented so the next round is corrected with purpose.

Bulk Production
After approval, the product enters fitness clothing production with confirmed specs, materials, trims, colorways, size breakdowns, labels, and quantities.
11
QC and Packaging
Quality control checks finished garments before shipment: measurements, stitching, trims, labels, folding, and packing.
The clearer the product is before sampling, the fewer decisions the factory has to guess.
