Frequently Asked Questions
Custom Down Jackets Manufacturing FAQs
Have a specific question about fill powers, down ratios, or baffle construction? Get in touch with our team.
Inquire About Your Project →What information should I provide for a custom down jacket quotation?
Share your tech pack or design sketch, shell fabric preference (e.g. 400T nylon ripstop or recycled polyester), fill power choice (650, 700, 800, or 850), down-to-feather ratio (90/10 or 80/20), baffle construction (box-wall or sewn-through), hardware specs, size breakdown, and order quantity. We will promptly provide a comprehensive FOB quotation and development plan.
What is your minimum order quantity (MOQ) for custom down jackets?
Our MOQ is 300 pieces per style/color using export-grade stock downproof shell fabrics and RDS-certified down, and 2,000 pieces per style/color for custom-milled shell fabrics, custom membrane laminations, or custom dyed colors.
Are your down and feathers certified under the Responsible Down Standard (RDS)?
Yes, 100% of the duck and goose down sourced by SM Global Apparel is certified under the Responsible Down Standard (RDS), ensuring animal welfare, humane treatment, and complete supply chain traceability from farm to factory.
What is the difference between box-wall and sewn-through baffle construction?
Sewn-through construction stitches the outer shell directly to the lining, creating lightweight, packable chambers with minor heat loss at the seams. Box-wall construction inserts vertical fabric baffles between the shell and lining, creating three-dimensional cubes that completely eliminate cold spots for extreme sub-zero weather.
How do you prevent down feathers from leaking through the stitching?
We use high-density 380T/400T ciré-coated downproof fabrics, dense anti-static down bags, and specialized rounded micro-needles (SES points) with silicone-lubricated core-spun thread to seal needle punctures and eliminate feather migration.
How long do sample development and bulk production take?
Proto and technical fit samples take 10–15 days. Bulk manufacturing takes approximately 15–30 days after Pre-Production (PP) sample approval, depending on styling complexity and order volume.
Do you handle worldwide shipping and export documentation?
Yes, we ship globally via ocean freight from Chattogram Port or air freight from Dhaka Airport, handling commercial invoices, packing lists, Bill of Lading, and GSP origin certificates for duty-free access.
Custom Down Jackets Manufacturing in Bangladesh for Global Performance Brands
Partnering with a specialized custom down jackets manufacturer in Bangladesh gives international outdoor performance brands, alpine technical labels, and luxury streetwear companies access to world-class down garment engineering at highly competitive FOB rates. Natural down jackets represent the highest tier of cold-weather outerwear: they deliver an extraordinary warmth-to-weight ratio that synthetic fibers cannot fully replicate, compressing effortlessly into small travel pouches while springing back with instant loft upon release.
At SM Global Apparel, we manage every phase of down outerwear production from sourcing certified Responsible Down Standard (RDS) goose and duck plumage and downproof 380T–400T micro-ripstops to computerized multi-nozzle down injection, precision baffle sewing, in-house quality audits, and global export logistics. Operating from Dhaka, Bangladesh, we manufacture alpine mountaineering down parkas, ultralight packables, and urban lifestyle puffers tailored strictly to your brand’s tech packs.
Fill Power & Down Composition: 650 to 850+ Loft Explained
Fill power is the universal metric measuring down quality and insulating efficiency. It represents the volume in cubic inches that one ounce of down occupies when placed in a standardized testing cylinder under controlled temperature and humidity. Higher fill power means larger, mature down clusters with more microscopic air pockets, trapping more body heat with less weight.
We supply duck and goose down ranging from commercial 650 fill power (ideal for casual urban puffers) up to elite 800 and 850+ fill power white goose down (engineered for sub-zero alpine summit jackets). All down lots are certified with 90/10 or 80/20 down-to-feather ratios, thoroughly washed, sterilized, and tested under IDFL protocols to ensure an oxygen cleanliness rating below 10 and turbidity exceeding 1000mm for hypoallergenic, odor-free comfort.
Baffle Architecture: Box-Wall vs Sewn-Through Engineering
Baffle construction determines how warmth is retained across the body. In sewn-through (quilted) construction, the exterior shell is stitched directly to the inner lining, creating horizontal or diamond channels. This design is exceptionally lightweight and breathable, making it the preferred method for transitional spring/autumn jackets and packable mid-layers.
For severe alpine and sub-zero conditions, SM Global Apparel builds complex box-wall baffles. By stitching vertical fabric walls (baffles) between the inner and outer shell fabrics, we create three-dimensional rectangular chambers. This ensures down clusters loft evenly across the entire surface without pinch points, eliminating thermal bridges and cold spots along seam lines.
Downproof Textile Technology: 380T–400T Ripstop & Anti-Leak Needle Craft
The primary quality vulnerability in down outerwear is feather leakage. If sharp feather quills puncture through the fabric weave or needle holes, the jacket sheds insulation and creates consumer dissatisfaction. To prevent this, we source ultra-dense 380T to 400T high-tenacity nylon and polyester micro-ripstops that undergo calendar ciré finishing—heat and roller pressure that smooths and seals the fabric pores.
During sewing, our lines utilize specialized slim rounded needles (SES/SUK points) and silicone-lubricated core-spun threads. The rounded needle point gently displaces fabric yarns rather than cutting them, allowing the yarns to snap back tightly around the thread and forming an impenetrable barrier against down migration through repeated domestic laundering.
Quality Assurance, AQL 2.5 Standards & Duty-Free Export Advantages
Quality assurance is essential for high-ticket outerwear programs. Our internal testing laboratories conduct strict pre-production and in-line audits, including baffle down leakage tumble tests (EN 12132), loft compression recovery trials (ASTM D3574), DWR water repellency spray rating (ISO 4920 rating 5.0), and seam tensile strength. Every finished jacket undergoes 100% metal detector screening before carton packaging.
Manufacturing in Bangladesh offers international buyers substantial financial advantages through preferential duty-free tariff agreements under GSP schemes to the European Union, the UK, Canada, and Australia.
