Waterproof Breathable Fabric Sourcing Program for Denim Mills: Underwear
Waterproof Breathable Fabric Programme for Denim Mills: Underwear
This programme covers the full path from a waterproof breathable fabric requirement to a repeatable bulk supply for denim mills. Instead of buying whatever a catalogue happens to stock, you specify the base material, the 110 gsm, the finish and the packing, and we hold that specification so every reorder matches the last one. It is built around underwear, which is where most of the specification detail sits.
The most common failure in waterproof breathable fabric sourcing is not price — it is drift. A base material changes mill, the shade moves, a plating bath changes and the item quietly stops matching the approved sample. We prevent that with a written spec, an approved counter sample and a golden sample retained at the factory.

What the programme covers
- Specification build from your tech pack or a physical reference sample
- Base material and finish options with costed alternatives
- Sampling, testing and approval against California Prop 65
- Bulk production with in-line inspection and photo reporting
- Packing, documentation and shipment under the agreed Incoterm
Recommended specifications
- Genuine Leather — best balance of cost, availability and test performance
- POM Plastic — best balance of cost, availability and test performance
- ABS Resin — selected for colour depth and finish stability
- Iron — best balance of cost, availability and test performance

FAQ
What is the minimum order quantity?
Standard MOQ is 500 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
Which compliance documents do you provide?
California Prop 65 documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
What are the payment and delivery terms?
Standard terms are a deposit with the order and the balance before shipment, under EXW / FOB / CIF / DDP as agreed.
Send the reference sample or tech pack and we will come back with a costed specification, a sampling timetable and the compliance documents your market requires.
