Down jacket quotations vary because the filling is only one part of the product. Down type, fill power, fill weight, shell fabric, baffle construction, trims, testing, order breakdown and packing all affect the final manufacturing cost.
For brands comparing OEM quotes, the useful approach is to hold the specification constant. Two jackets described only as 鈥?0/10 down鈥?may differ substantially in warmth target, down quantity, fabric, construction and quality requirements.
Quick answer
The largest down-jacket cost drivers are usually the insulation specification, fill weight, shell and lining fabrics, baffle design, hardware, order quantity and required tests. Ask suppliers to quote from the same tech pack, bill of materials, size range, colour breakdown, packing and Incoterm.
| Cost area | What changes the quote | What buyers should specify |
|---|---|---|
| Down filling | Type, composition, fill power, origin and fill weight | Approved specification and required documentation |
| Fabric | Weight, downproof construction, finish, coating and colour | Shell, lining and pocketing specification |
| Construction | Baffle count, quilting, chambers and complex panels | Drawings and workmanship standard |
| Trims | Zippers, snaps, adjusters, branding and labels | Brand, finish, colour and approval sample |
| Order plan | Quantity by style, colour and size | Complete order breakdown and delivery terms |
Goose and duck down, down-to-feather composition and fill power influence material cost and product positioning. Higher fill power can provide more loft for a given weight, but the correct choice depends on the warmth target, garment volume and market. Buyers should request documents for the exact filling used rather than relying on a general supplier statement.
Fill power does not state how much down is inside the jacket. Fill weight is the quantity of insulation allocated to a garment or chamber. Larger sizes may require a grading plan rather than one identical fill quantity across the full range. Confirm whether the quotation uses estimated or approved fill weights.
Lightweight downproof fabrics need to balance air permeability, leakage control, strength, hand feel and appearance. Custom colours, prints, coatings and water-repellent finishes can introduce material minimums or testing. Evaluate the fabric with the selected down and seam construction.
Simple stitch-through quilting and more complex chamber constructions require different labour and materials. Numerous small baffles, shaped panels and special filling sequences increase handling. Construction should follow the warmth, silhouette and leakage-control needs rather than decoration alone.
Two-way zippers, detachable hoods, inner cuffs, multiple pockets, custom pulls and branded labels add material and sewing operations. Ask which trim brands and finishes are included in the quote and whether colour development or tooling is separate.
Possible checks include filling composition, fill power, cleanliness, leakage, dimensional stability, colourfastness and finished-garment workmanship. Requirements vary by market and buyer. Agree on methods, sample source and responsibility for testing or retesting before production.
For the full production sequence, see the down jacket manufacturing guide.
Use the same tech pack and bill of materials.
State fill power, composition and fill weight separately.
Provide quantity by colour and size.
Confirm samples, tests and inspection included.
Compare the same packing and Incoterm.
Ask which assumptions could change the final price.
Fill power is one cost factor, but fill weight, down type, fabric, construction and order details also matter. Compare complete specifications.
The source, fill power, cleanliness, fill weight, documentation and market conditions may differ, while the rest of the jacket specification may also be unequal.
Set a clear warmth and use target, avoid unnecessary construction, confirm material minimums early and compare quotes from one complete specification.
