Oversized Shirt Customization Program for Mining Operations with Seam Sealing
Oversized Shirt Customization Program for Mining Operations
This programme covers the full path from a oversized shirt concept to repeatable bulk supply for mining operations. The build starts from everyday-casual references — oversized shirt in cotton jersey — then locks fabric weight, wash behaviour and fit tolerance so every reorder matches the approved sample.
Most oversized shirt buyers arrive with one of these problems: wholesale costs squeezed the retail margin, or the fabric felt thinner than the approved sample. The fix is a written spec before bulk: shrinkage allowance, stitch density, colour tolerance and a golden sample kept at the factory.

How we produce it
- Tech pack review, fabric confirmation and lab dip approval

- Fit sample and wearer test, then pre-production sign-off
- Bulk cutting with seam sealing applied under controlled settings
- In-line inspection, final AQL 2.5 check and packing
Quality control
Every bulk lot is compared against the approved sample for shade, hand feel, measurements and wash behaviour. Oversized Shirt reorders stay comparable over time because the spec, the lab dip and the golden sample are all on file.
FAQ
What file formats do you need for artwork?
Vector files (AI, EPS, PDF) give the best print and embroidery results. For raster artwork please supply at least 300 dpi at the final print size. We digitise embroidery files in-house and return a sew-out photo for approval.
How long does sampling take?
A first prototype is typically ready in 12 working days after the tech pack is confirmed, including fabric sourcing if the base cloth is not in our stock library. Revisions add about 4 days each.
How is shipping handled?
We quote EXW, FOB, CIF and DDP. Consolidated sea freight is the default for bulk programmes, with air or express options when a launch date is at risk.
What is the minimum order quantity?
Standard programmes start at 100 pieces per style and colour. We can split sizes across a size set, and for first orders we often accept a mixed-colour run to help you test the market.
