Modular backpack programmes built on one fixed interface

A modular backpack programme is a range built around a single published attachment grid, so every pouch and module stays interchangeable across future production runs. Our production team works to 25 mm webbing with a 38 mm channel interval and a 50 mm horizontal repeat; MOQ is 500 units per colourway, sampling takes 6-10 working days and bulk production runs 35-50 days. This page covers civilian load carriage only — hiking, commuting, work tools, travel and first aid — and makes no claim about weapon carriage, protective armour or any military certification.

Modular backpack with detachable pouches on an attachment grid

What makes a carry system modular

Modularity is not a pocket count. It is an interface contract: a published grid geometry, a documented attachment method, and a change-control rule that keeps old modules working on new shells. When those three exist, a brand can extend a range without re-developing the carrier, and a buyer can replace one worn pouch instead of a whole bag.

Where the interface is left undefined, the opposite happens. Two pouches that look interchangeable behave differently, a material substitution quietly changes the channel clearance, and the installed base stops being an asset. That is why the interface drawing — not the rendering — is the document we version and sign.

Locked programme parameters

Every programme runs on the same published numbers. They are listed here so a brief can be costed without a round of clarification.

How a programme runs

  1. Brief and interface. Target volume, module list, grid geometry, destination market. Quote returned within 24-48 hours.
  2. Sampling. 6-10 working days, or 12-15 for moulded frames or custom hardware. Sampling fee USD 50-150, refundable against the order.
  3. Testing. Method, sample size and acceptance threshold agreed before production, not after.
  4. PP sample. The approved pre-production sample becomes the reference for bulk inspection and for every repeat order.
  5. Bulk and inspection. 35-50 days, inspected to AQL 2.5 under ISO 2859-1 at level II.
  6. Shipment. FOB Xiamen by default; sea 25-35 days, air 5-8 days, express 3-5 days.

Frequently asked questions

What is a modular backpack?

A modular backpack is a carry platform built around a standardised attachment grid, so pouches and modules can be added, moved or removed without changing the main bag. The interface — not the bag shape — is what makes a system modular. Our programmes run on a published grid geometry of 25 mm webbing with a 38 mm channel interval and a 50 mm horizontal repeat.

What is the MOQ for a custom modular backpack programme?

The MOQ is 500 units per colourway. That figure reflects fabric minimums, trim minimums and line setup, not an arbitrary threshold. Where a launch needs three colourways, the practical first order is 1,500 units spread across the range rather than 500 of one colour.

How long does sampling and bulk production take?

Sampling takes 6-10 working days, and 12-15 working days for complex builds with moulded frames or custom hardware. Bulk production runs 35-50 days after PP sample approval. Sea freight is 25-35 days, air is 5-8 days and express is 3-5 days, so a launch date should be planned roughly 90 days out.

What does MOLLE compatibility actually require?

Geometric compatibility and load compatibility are two different things. A pouch strap must pass through the channel with working clearance, which is why 25 mm webbing at a 38 mm channel interval is the widely published geometry for PALS-style grids. Bar-tack placement and webbing tension then determine whether the attachment survives repeated use.

Which inspection standard is used for bulk orders?

Inspection is to AQL 2.5 under ISO 2859-1 at general inspection level II, with Critical 0, Major 2.5 and Minor 4.0. The acceptance threshold, defect list and responsible laboratory are agreed and written into the specification before production, not after.

What are the standard commercial terms?

Quotations are returned within 24-48 hours. Payment is T/T 30/70 and the default shipping term is FOB Xiamen, with CIF or DAP quoted on request. Sampling fees run USD 50-150 and are refundable against the order; tooling and screens run USD 300-2,500 depending on the branding method.

Can an existing bag design be adapted into a modular platform?

Yes, and it is usually the faster route. An existing shell can be re-engineered to carry a standard attachment grid, which keeps the fit work already done and adds the module ecosystem. The control point is the interface drawing: once the grid geometry is fixed and versioned, modules stay interchangeable across future production runs.

What production capacity sits behind a programme?

Programmes are coordinated through a 4,950 m² SGS-verified production floor with 137 people, 7 production lines and 149 machines, at 200,000 units per month. Capacity planning is done per line, so expedited requests depend on which line is free rather than on how urgent the order is.
