Product Development & Sampling

From brief to tech pack

After the quotation is accepted, a tech pack is prepared from your brief and sent to you for approval before sampling. The tech pack translates intent into instructions. A reference photo shows what a cap looks like; a tech pack says how it is built, in which materials, with which measurements and colors.

• Construction: panel count, crown profile, structure, eyelets, top button and seam finish.
• Materials: shell fabric, mesh, sweatband, lining and brim board.
• Artwork and placement: each logo with size, position and distance from a reference seam or edge.
• Decoration method: flat embroidery, 3D puff, patch type or print method per position.
• Colors: fabric, thread and trim colors, referenced by Pantone TPX or TCX codes or physical swatches.
• Dimensions: crown height, brim length and width, size or size range.
• Trims and labels: closure type, seam tape, inside labels, hangtags and packaging.

Read the tech pack line by line. Every unchecked assumption becomes part of the sample. The guide on cap tech packs shows a complete example.

Sample types and when to use them

Not every project needs every sample type. Choosing the right one saves time and keeps the development budget proportional to the order.

For a private label cap on an existing base style, a single pre-production sample is often enough. For a new pattern, a proto sample in available fabric comes first, so shape and fit are settled before final materials are committed.

Timing and revision rounds

Sampling typically takes 7 to 14 days depending on design, counted from tech pack approval. Custom components such as dyed fabric, woven labels or engraved closures may not be available in final form for the first sample. In that case, the sample uses the closest available substitute and the difference is noted on the tech pack.

1. Tech pack approved by the buyer.
2. Sample produced and checked internally against the tech pack.
3. Sample sent with photos and measurements.
4. Buyer reviews and returns comments in writing, ideally marked on photos.
5. If changes are needed, the tech pack is revised and a new sample round starts.
6. Buyer approves the sample in writing. That sample and tech pack version are the bulk standard.

Each revision round restarts the sampling clock. Consolidate comments into one reply instead of sending them over several days. Separate must-change items from preferences, so the next round addresses what matters.

Giving useful feedback

Write comments as measurable instructions where possible. Lower the crown by a small amount, move the logo closer to the brim, use a darker thread shade: each of these can be translated directly into the next tech pack. Comments such as make it look more premium are hard to act on without a reference, so attach a photo of a cap that shows what you mean.

What to check on a sample

• Overall shape: crown height, front slope and how the cap sits on the head.
• Panel alignment and center seam position relative to the front logo.
• Brim curve, length and stitching rows.
• Embroidery size, position, density and legibility of small details.
• Colors under daylight against your Pantone or swatch references.
• Closure function and size adjustment range.
• Sweatband comfort, seam tape and label positions.
• Hangtag, sticker and polybag details if packaging is part of the sample.

Photograph the sample on a head form or a person from the front, side and top. Comments are clearer when they point to a specific spot in an image. The custom headwear sampling guide covers review technique in more depth.

The cost of change by stage

The later a change is made, the more it costs. This is not a policy; it follows from what has already been ordered or produced.

Once the sample is approved, the project moves to bulk production. Material ordering, decoration setup and the quality control plan are all based on the approved sample. For construction decisions to settle before sampling, see cap construction and panel design.
