Work Jacket Zipper Specification for Uniform Buyers

A work jacket zipper specification should tell the sample maker what each opening needs to do. A driver may want to release the lower front while seated. A technician may need to open a chest pocket with gloves on. Write a separate line for each opening before requesting prices for your custom work jackets.

Choose how the jacket opens

For a jacket that comes off like a coat, specify a separating front zipper. If the wearer also needs to open the front from the hem while the upper section stays fastened, ask to sample a two-way separating design. For a pocket, describe which end the pull should rest at when closed. Mark that end on a front-view sketch so the reviewer can check it without guessing. For illustrated component definitions, see YKK’s zipper classification guide.

Give the pattern maker a measurable reference

Photograph the sample laid flat with the zipper closed. Mark the intended start and finish on the photograph. Specify the unit beside every measurement, especially when a European supplier and a US buyer share one worksheet. Ask the supplier to confirm the measuring points for the proposed component. YKK illustrates different endpoints by zipper construction in its measurement diagrams.

Test the opening during a normal shift task

• At the collar. Ask the wearer to fasten the jacket over the usual work layers and turn their head. Record whether the pull or upper edge touches the chin.
• At the hem. Have the wearer sit in a normal working position. If a two-way opening was requested, check that they can reach and operate the lower pull comfortably.
• At the pockets. Use the actual gloves and the item normally carried. Record which hand opens each pocket and whether the lining catches during use.

Keep a photo of each requested change alongside the sample size and revision date. Use the garment sample approval checklist to carry the accepted details into the production reference.

A zipper brief you can copy into your enquiry

Garment and opening: [style reference and front, chest or side pocket]
Required action: [describe what the wearer must be able to do]
Dimensions: [sample size, unit and marked photo]
Appearance: [tape colour, visible teeth, pull shape or logo]
Approval: [who checks the sample and which changes require another review]

When comparing quotations, ask each supplier to identify the zipper it priced and flag any proposed substitution. Send the marked sketch, quantities by size and colour, delivery destination and required date with your work jacket quote request. Component choice and sample arrangements can then be reviewed against your brief.
