How to Brief Jeans Pocket Bags and Coin Pockets

1. Map Each Pocket and Define Its Function

Begin with a labeled front and back flat sketch that assigns an identifier to every pocket component. Separate the front opening, facing, pocket bag, back pocket, and coin pocket rather than grouping them under a single pocket note. On conventional five-pocket jeans, front pockets normally use separate pocket bags, while back pockets are usually patch pockets and do not automatically need an internal bag. If your design uses welt back pockets, lined patch pockets, or concealed internal compartments, state that explicitly and provide a section drawing. This prevents the factory from quoting or sampling a different construction based on an ambiguous reference image.

For each pocket, define its intended use and the dimensions that control that use. Show finished front bag depth and width, opening length, curve shape, and the reference points used for measurement. Explain whether depth is measured vertically from the opening or along a defined seam, because those methods can produce different readings. For back pockets, specify finished width, height, corner shape, spacing, and placement relative to the center back and yoke seam. Give the coin pocket its own width, depth, exposed height, and position within the front pocket area. Include grading rules or size-specific measurements wherever pocket placement or capacity changes across the size range.

2. Specify Pocketing Fabric Weight, Color, and Wash Behavior

Create a dedicated bill of materials entry for the pocketing fabric instead of describing it only as standard pocket cloth. Record fiber composition, woven construction, target weight in gsm, color, and any required finish. Choose the weight around the denim weight, silhouette, intended carrying use, and desired hand feel rather than assuming that heavier material is always better. A bulky bag can show through a close-fitting style, while a very light fabric may not suit repeated carrying loads. Ask the supplier to identify the proposed material and disclose alternatives before sampling. Any acceptable weight tolerance or substitution rule should be written into the brief and confirmed before cutting.

Use an approved physical swatch or a clearly identified color reference for white, natural, grey, black, or colored pocketing. State whether a digital image is only a visual guide and who approves the final shade. Consider how the bag looks through the denim, at the pocket opening, and inside the finished garment. Record the garment wash process relevant to sampling, then evaluate the pocketing together with the denim rather than separately. Different dimensional changes can cause puckering, pulling, or a bag that hangs incorrectly after washing. If you require shrinkage or colorfastness testing, define the method and acceptance criteria with the supplier; do not assume a material name proves performance.

3. Detail Seams, Bartacks, Coin Pocket Assembly, and Branding

Show pocket seam construction in enlarged drawings with a written stitch description. Specify the stitch type for assembly, the edge finish used to contain raw edges, the seam allowance, and the stitch density or agreed range. If using a stitch classification code, pair it with a plain-language description so the factory can flag any mismatch. Identify thread material, size or supplier reference, and color separately for hidden assembly and visible topstitching. Mark each bartack location and define its finished length, direction, and approved appearance. Reinforcement should secure the relevant layers without unintentionally closing usable pocket space. Where rivets replace or supplement bartacks, cross-reference the hardware specification rather than leaving that decision to the sewing line.

Give the coin pocket a construction sequence where its layers overlap the front opening, facing, or pocket bag. Define the top hem, edge turnbacks, stitch rows, reinforcement points, and opening clearance after assembly. Check that the coin pocket is usable and that its attachment does not create an uncomfortable lump or restrict access to the main pocket. For branding on pocket bags, attach final artwork with dimensions, print colors, placement measured from named edges, and orientation when viewed inside the jeans. State whether printing occurs before assembly and whether the artwork must remain legible after the intended wash. Ask for approval of print appearance and hand feel on the actual pocketing material before bulk production.

4. Build the OEM Tech Pack and Approve the Finished Sample

Organize the China denim OEM tech pack so each pocket instruction has one authoritative location. Include the style number, revision date, sample size, size range, pocket identifiers, dimension table, tolerances, bill of materials, construction drawings, stitch notes, reinforcement map, and branding artwork references. Mark measurements as before wash or after wash and avoid mixing those conditions within an unlabeled table. Add an approval column for unresolved materials or construction decisions, with a named buyer contact responsible for closing them. When sending reference garments or photographs, explain which features are mandatory and which are illustrative. Ask the factory to return a written list of assumptions, material substitutions, and construction questions before sample work begins.

Review the completed sample from both the outside and the inside after the agreed finishing process. Measure pocket placement and usable capacity, check symmetry, inspect seam closure, and confirm that pocket bags lie flat without protruding below intended internal boundaries. Put a hand through each opening and assess access, rough reinforcement, trapped fabric, and interference from the coin pocket. Compare branding placement and readability with the approved artwork. Record every change with annotated images, revised measurements, and a new tech pack revision rather than relying on scattered messages. MOQ is 100 pcs, and samples take approximately 7 days once the brief and materials are confirmed. Bulk timing depends on quantity and should be agreed after sample approval and scope confirmation.
