We source 100% certified duck and goose down traceable through IDFL audits. Our supply chain adheres to strict animal welfare standards, guaranteeing zero live-plucking and zero force-feeding.
DWR-nano coated down clusters resist moisture uptake, retaining thermal loft even in 90%+ relative humidity environments and drying 70% faster than untreated raw down feathers.
Eliminate needle puncture holes using ultrasonic heat-bonded channel lamination. This prevents down leakage (feather loss) and increases total windproofing/waterproofing ratings.

As brands plan their seasonal bulk apparel buying, the down outerwear sector is undergoing a massive shift driven by consumer demand for verifiable sustainability, high-performance textile lamination, and flexible low-MOQ supply chains. China remains the undisputed global hub for down jacket manufacturing, producing over 70% of the world’s down-filled outerwear. However, modern procurement teams require far more than basic cut-and-sew capabilities; they demand full material traceability, automated down injection precision, and zero-defect quality control protocols.
Strategic buyers from the USA, Europe, the UK, Australia, and the Middle East are re-aligning their supply chain metrics around four major technological and structural shifts:
China's apparel manufacturing sector has evolved from labor-intensive manual assembly into a high-tech automated power station. When evaluating custom jacket suppliers in key clusters like Zhejiang, Jiangsu, and Guangdong, buyers benefit from distinct technological advantages:
Automated Computerized Down Injection: Manual down stuffing causes uneven Gram-per-Square-Meter (GSM) weight distribution across jacket panels, resulting in cold spots. Modern OEM factories utilize sealed, vacuum-assisted computerized down injection machines accurate to 0.01 grams. This ensures every individual baffle chamber receives exact down fill density matching tech-pack parameters.
Down-Proof Shell & Lining Weaving Innovations: High-loft down requires specialized down-proof fabrics (typically 20D–40D high-density ripstop nylon or calendared micro-polyester). Chinese textile mills now produce ultra-lightweight 15D down-proof fabrics that weigh under 30g/m² while maintaining complete feather retention, enabling packable ultra-light winter jacket lines.
Our senior apparel merchandisers and textile engineers will review your design sketches, calculate exact down fill weights, and recommend optimal fabric laminates free of charge.
With over 16 years of international outerwear manufacturing leadership, Oasis Jackets (a core operating unit of Dioz Group) bridges the gap between western brand expectations and agile factory-direct execution. Serving over 5,000 B2B buyers across 55 countries, our enterprise manufacturing infrastructure is designed to mitigate procurement risk at every touchpoint.
Our manufacturing operations carry ISO9001 quality management, BSCI social compliance, GRS, OEKO-TEX Standard 100, and IDFL down verification certificates, making custom clearance and brand audits seamless.
We eliminate extreme factory order barriers. By maintaining an extensive mill inventory of high-grade down-proof shell fabrics and pre-tested pattern blocks, emerging private label brands can launch with realistic order volumes.
Every element is customizable: custom Pantone yarn dyeing, branded YKK/SBS zipper pulls, embossed leather chest patches, custom woven neck tags, silicon seam labels, and custom polybags.
Headquartered in Beverly Hills, CA, with regional account teams across the UK, UAE, Australia, Germany, France, and Brazil. Orders move under DDP, FOB, or EXW terms with guaranteed customs handling.
Direct answers to technical, commercial, and operational questions asked by apparel sourcing directors and private label buyers.
Our minimum order quantity depends on the degree of customization required. For standard private-label down jackets utilizing in-stock down-proof shell fabrics (20D/30D ripstop nylon or micro-polyester), MOQs start as low as 200–300 pieces per style/colorway. For fully custom mill-dyed pantone colors, specialized 3-layer laminated membranes, or custom engineered woven baffles, mill fabric minimums generally require 500 to 1,000 pieces per program.
Every batch of down utilized in our production lines undergoes independent laboratory testing by the International Down and Feather Testing Laboratory (IDFL). We provide certified documentation verifying Fill Power (FP) ratings (550FP to 800FP+), Down Cluster percentage (e.g., 90/10 vs 80/20), turbidity (cleanliness rating > 1000mm), and net weight. Furthermore, 100% of our duck and goose down is Responsible Down Standard (RDS) or Global Recycled Standard (GRS) certified, ensuring complete farm-to-jacket traceability.
Down leakage is avoided through four engineering controls: 1) We specify high-density down-proof shell and lining fabrics coated with anti-static calendaring finishes; 2) We utilize dedicated 4-layer construction (Outer Shell + Down Bag Inner 1 + Down Bag Inner 2 + Lining) for heavy puffer styles; 3) We use specialized anti-friction ballpoint sewing needles and elasticized down-proof threads that seal needle punctures; 4) For seamless collections, we employ ultrasonic bonded baffle technology eliminating stitch holes altogether.
The standard development timeline is 7–12 business days for initial pattern making and proto-sample creation. Once the sealed pre-production sample (PP sample) and lab dips are approved by your team, bulk production typically requires 30–45 days depending on total order volume and trim complexity. Air freight delivery requires 5–9 days, while standard sea freight takes 20–35 days depending on the destination port.
Yes. Private label manufacturing is our primary core business. We operate under strict Non-Disclosure Agreements (NDAs). All manufactured garments feature exclusively your custom branding: woven main neck labels, wash/care tags complying with US FTC / EU regulations, custom hangtags, branded zipper pulls, silicone badges, and custom polybag packaging. No reference to Oasis Jackets appears on your commercial merchandise.
We execute inline inspection protocols at four distinct production stages: Raw Material Intake (4-point fabric inspection), Cut-Piece Audit, Hourly Sewing Line QC (checking baffle down weight distribution and symmetry), and Final Pre-Shipment Inspection following standard AQL 2.5 (Acceptable Quality Limit) parameters. Third-party inspection agencies such as SGS, Intertek, or Bureau Veritas are fully welcomed to audit orders prior to final balance clearance.
