Choosing a travel bag for a private-label or branded line starts with the end user’s trip profile, not the logo. Define trip length, carry method, and market compliance first, then lock fabric denier, hardware grade, and QC thresholds with your factory. A short spec sheet up front prevents the costly rework that comes from sampling a product built for the wrong use case.
Start With the Use Case, Not the Style
A factory can build a duffel, a wheeled case, or a backpack from the same blueprint, but each serves a different traveler and a different margin. Before requesting samples, write down three things: the longest typical trip (day trip, weekend, one week, multi-week), how the piece moves (shoulder, wheels, or hybrid), and the sales channel (airport retail, club store, promotional). These answers decide every spec below.
- Weekend and short-haul: 20–40 L duffels and packs, light and compressible.
- One-week trips: 40–55 L carry-ons that stay within IATA dimensions of roughly 56 x 36 x 23 cm.
- Extended travel: 60 L+ checked formats where weight and structure matter more than gate fit.
Capacity Tiers and the Markets They Fit
Capacity is the first filter buyers use. The table below maps volume to a typical buyer and the construction it implies.
| Volume | Typical use | Shell weight target | Common closure |
|---|---|---|---|
| 20–30 L | Day trips, gym-to-hotel | 400–600 g | Zip + magnetic flap |
| 30–40 L | Carry-on, 2–4 nights | 600–800 g | U-zip main |
| 40–55 L | One-week travel | 800–1,100 g | Dual zip + lockable |
| 60 L+ | Checked, extended | 1,100 g+ | Wide mouth + wheels |
Leave roughly 20% headroom in the spec for the return trip. A piece that is full on departure leaves no room for purchases and forces over-stuffing that stresses zips.
Shell Fabric: Denier, Coating, and Compliance
Denier (D) measures yarn thickness; higher numbers mean a denser weave. For travel programs, 600D polyester is the entry workhorse, 900D–1200D balances weight and scrape resistance, and 1680D ballistic nylon is the durable top end. Pair the shell with a PU or TPU coating of 0.15–0.3 mm for water resistance without stiffness.
- 600D polyester: cost-efficient for promotional and light-use programs.
- 900D–1200D: the common choice for branded retail lines.
- 1680D ballistic nylon: abrasion resistance for wheeled and checked formats.
- Recycled variants: rPET at 600D–900D meets many EU retailer sustainability asks.
Compliance is not optional for cross-border programs. For the EU, confirm REACH conformance for dyes and coatings; for California and broader US retail, Prop 65 limits apply to certain phthalates and lead. OEKO-TEX Standard 100 or GRS documentation supports both market access and buyer audits.
Hardware and Construction That Survive Freight
Most travel failures happen at stress points, not in the panel. Specify hardware before color. Use self-repairing coil zips rated to the load, bar-tack every strap anchor with double stitch rows, and reinforce the base with a moulded or layered panel. A wide, non-slip shoulder strap and a luggage pass-through sleeve are now baseline expectations for carry formats.
- Zips: coil #5–#10 depending on opening size; opt for branded, self-repairing coils.
- Stitch density: 8–10 SPI (stitches per inch) at load-bearing seams.
- Base: reinforced or molded panel to take floor contact and scuffs.
- Wheels (if used): sealed bearings and a wide wheelbase beat extra pockets for durability.
Quality Control Checkpoints to Put in the PO
Write QC into the purchase order, not the conversation after defects appear. A standard consumer-goods plan uses AQL 2.5 for major defects and AQL 4.0 for minor, with inline checks at 20% and 80% production plus a final audit. Add a drop test from 1.2 m onto a hard surface for wheeled and checked formats, and a zip-cycle test of 5,000+ openings.
- Confirm fabric weight and coating thickness on arrival at the factory.
- Check stitch density at three random seams per batch.
- Verify hardware pull strength at strap anchors (target 20 kg+).
- Run a water-spray test on the coated shell.
- Hold a final AQL inspection before carton sealing.
Production Basics: MOQ, Lead Time, Packaging
Plan the run around realistic minimums. A typical cut-and-sew travel program runs a MOQ of 300–1,000 units per colorway, with a development sample in 7–12 days and bulk lead time of 35–55 days after approval. Carton size and weight drive freight cost more than the product itself, so specify a flat-pack or structured pack and confirm carton dimensions with your forwarder before tooling.
Build reorder timing into the plan from the start. A 35–55 day bulk window plus ocean transit of 25–40 days means a reorder placed after stockout arrives two to three months later. For seasonal markets, lock the second run before the first lands, and keep a technical file—approved sample, test reports, and spec sheet—so repeat orders stay consistent without re-sampling each time.
How to Brief a Factory in One Page
A clear spec sheet turns a vague request into a repeatable product. Include: target volume and use case, shell material and denier, coating thickness, hardware grade, compartment layout, compliance marks required, QC plan, MOQ, and target landed cost. Share a tech pack with a technical drawing rather than a lifestyle photo; a drawing removes the ambiguity that leads to wrong first samples.
Sourcing Mistakes That Cost the Program
- Choosing fabric by price alone, then discovering it fails a spray test in season one.
- Skipping REACH or Prop 65 documentation until a retailer audit blocks shipment.
- Setting MOQ below tooling efficiency, which raises unit cost and delays the line.
- Approving a sample built by hand when bulk uses different machines.
Turn the Spec Into a Quote

Frequently Asked Questions
What denier fabric is best for a travel bag line?
For most branded retail programs, 900D–1200D polyester offers the right balance of weight, scrape resistance, and cost. Use 1680D ballistic nylon for wheeled or checked formats that take harder handling, and 600D for light promotional use.
Which compliance marks do I need for EU and US retail?
For the EU, REACH conformance for dyes and coatings is the baseline, with OEKO-TEX Standard 100 supporting buyer audits. For US retail, Prop 65 limits apply to specific phthalates and lead. GRS helps if you specify recycled content.
What MOQ should I expect for a custom travel bag?
Most cut-and-sew programs start at 300–1,000 units per colorway. Below that, tooling and setup costs push the unit price up and can extend lead time.
How long does development and bulk production take?
A development sample usually takes 7–12 days. After approval, bulk production runs about 35–55 days, depending on order size, hardware sourcing, and compliance testing.
What QC plan prevents defects at scale?
Specify AQL 2.5 for major defects and AQL 4.0 for minor, with inline checks at 20% and 80% production plus a final audit. Add a 1.2 m drop test for wheeled and checked formats.
Should I use recycled fabric for a travel bag?
Yes, if your buyers ask for it. rPET at 600D–900D performs close to virgin polyester for most travel uses and meets many EU retailer sustainability requirements, though it can cost slightly more per metre.
