What files do I need to turn a bag design into a sample?
A tech pack is useful, but a sketch, reference bag or AI-generated concept can begin a development discussion. Supply dimensions, views, materials, internal layout, carrying requirements and artwork where available. A concept image is a starting reference, not a complete manufacturing specification or proof that every pictured detail is feasible.
Show the parts a front image cannot explain
Include front, side, base and interior views. Identify openings, seams, gussets, pocket positions, strap attachment points and hardware. The base and interior often determine whether a bag stands, packs and opens as intended.
For a camera bag, show the equipment envelope and proposed dividers. For an insulated bag, describe the contents, handling and cleaning needs. Do not leave the team to infer these requirements from exterior proportions alone.
Separate required features from visual suggestions
Mark which dimensions, materials, brand colors and functional requirements are fixed. Identify where alternatives can be proposed. AI images can contain inconsistent seams, impossible openings or unsupported shapes; these details need review rather than literal copying.
A reference product can help explain a construction, but ownership and permitted use of designs and artwork must be clear. Discuss confidential-file handling before sending sensitive technical material.
Build the specification around measurable details
Use a consistent dimension order and units. Define finished bag measurements and the usable dimensions of critical compartments separately. Include handle drop, strap adjustment range and pocket depth when they affect use.
Add shell and lining references, reinforcement locations, zipper and hardware requirements, artwork dimensions and placement, and packaging needs. Acceptance criteria and required tests should be identified before the sample is approved.
Close open decisions before production approval
Use a numbered revision record so comments refer to one current design. Ask the team to identify unresolved construction or sourcing questions and document the approved choices.
A rendering, early prototype and approved production specification represent different stages. Confirm the scope and fee of any drawing, BOM or development work before proceeding; do not assume every design-support deliverable is included automatically.
