Explore our core line of high-performance marine apparel, dry suits, and technical gear engineered for extreme conditions.
In the highly competitive marine apparel landscape, the demand for uncompromising durability, hydrostatic integrity, and ergonomic movement has driven leading global outdoor brands to seek resilient, specialized manufacturers. Xiamen Yuelei Sports Co., Ltd. stands at the forefront of this industrial demand. Operating a state-of-the-art manufacturing facility in Xiamen, China, covering 1,600 square meters and staffed by approximately 30 skilled professionals, we specialize in high-performance OEM (Original Equipment Manufacturer) and ODM (Original Design Manufacturer) outdoor apparel, with a strict emphasis on marine jackets, dry suits, and technical ski outerwear. Our factory is fully equipped to provide comprehensive personalization services, allowing us to tailor our engineering specifications to the highly critical demands of international distributors, retailers, and commercial maritime operations.
Historical Context & Evolution: Xiamen Yuelei Outdoor Sports Co., Ltd., which acts as the manufacturing and research anchor for our flagship brand LKVER, initiated its operations by supplying high-grade ski jackets and specialized wetsuits on platforms like AliExpress in 2021. Due to an unprecedented surge in global orders and the widespread inability of outsourced third-party suppliers to meet our stringent quality standards and delivery timelines, our board made a strategic decision to transition into a direct manufacturing powerhouse. By establishing our own proprietary production workshop under the LKVER brand, we gained absolute control over the production loop. We have since expanded to host multiple international B2B platforms, handling complex bulk OEM contracts and technical customization workflows for hundreds of returning enterprise clients worldwide.
The performance of an offshore sailing jacket is governed by material science. Unlike standard outerwear, marine gear must withstand continuous salt-spray degradation, high hydrostatic pressures from heavy waves, and internal moisture buildup during high-exertion crew maneuvers. LKVER’s technical roadmap incorporates cutting-edge textile laminations and hardware integrations to deliver true professional-grade protection.
Our core sailing jackets utilize an advanced 3-layer (3L) laminate structure. The outer face is a high-density Nylon Taslan or Cordura ripstop treated with a highly durable hydrophobic finish. The middle layer houses an expanded polytetrafluoroethylene (ePTFE) or thermoplastic polyurethane (TPU) monolithic membrane. This membrane contains billions of microscopic pores per square inch—each pore is roughly 20,000 times smaller than a water droplet, yet 700 times larger than a water vapor molecule. This physical disparity ensures that rain and spray cannot penetrate the outer barrier while metabolic heat and sweat escape effortlessly.
| Performance Specification | Offshore Gold Standard (LKVER Limit) | Inshore / Coastal Grade | Testing Protocol |
|---|---|---|---|
| Hydrostatic Head (Waterproofness) | ≥ 20,000 mm H₂O | 10,000 - 15,000 mm H₂O | ISO 811 (Hydrostatic Pressure) |
| Moisture Vapor Transmission (MVTR) | ≥ 15,000 g/m²/24h | 10,000 g/m²/24h | JIS L 1099 B1 (Inverted Cup) |
| Water Vapor Resistance (RET) | < 6 m²Pa/W (Extreme Breathability) | 6 - 12 m²Pa/W | ISO 11092 (Sweating Hotplate) |
| Seam Strength (Hot Air Welded) | ≥ 350 N | 250 N | ISO 13935-2 |
To prevent the fabric face from "wetting out"—which blocks breathability and causes convective cooling—we employ advanced, eco-friendly C6 Durable Water Repellent (DWR) formulas. These formulations lower the surface energy of the textile fiber, forcing saltwater droplets to bead up and roll off instantly. Furthermore, metal snaps and zippers are susceptible to galvanic corrosion in marine environments. Consequently, LKVER uses marine-grade YKK AquaGuard® water-repellent zippers combined with injection-molded polymer sliders, eliminating metal-to-metal contact and preventing saltwater lockups.
Procuring sailing gear at scale requires a manufacturer capable of detailed customization and reliable bulk execution. LKVER offers a robust OEM/ODM framework built to translate corporate design requirements into production-ready technical patterns.
Whether our clients require technical crew apparel for commercial transport lines, search-and-rescue teams, or competitive yachting clubs, our product development process is highly structured:
Enterprise Customization Capacity: We support diverse customization requests, ranging from bespoke colorways matching corporate brand guidelines to custom-embroidered heat-sealed logos. Every seam intersecting a logo placement is re-taped from the inside to guarantee that waterproofing is never compromised by stitching.
The global outdoor apparel supply chain has experienced significant disruption over the past decade. By shifting from an outsourced model to our own physical factory, Xiamen Yuelei Sports Co., Ltd. insulated its clients from market delays. Our 1,600 square meter factory floor in Xiamen is engineered around lean manufacturing principles, which allow us to rapidly shift production lines between dry suits, sailing jackets, and ski apparel as seasonal demands fluctuate.
We employ a range of advanced machineries to maintain tight quality tolerances:
Xiamen's status as a major global shipping port further enhances our supply chain. By directly sourcing raw components from domestic performance mills and immediately exporting via Xiamen’s deepwater container port, we reduce transit overheads and slash shipping lead times by up to 20% compared to inland factories.
As global environmental frameworks tighten, major marine buyers are looking closely at the ecological footprint of their supply chains. Ocean conservation and eco-friendly manufacturing processes are integral to LKVER’s operational philosophy. We are actively shifting our material sourcing away from hazardous chemicals and toward circular, low-impact alternatives.
Our ESG integration plan encompasses three core initiatives:
Exporting technical outerwear involves navigating complex international standards and tariff codes. At LKVER, we support our clients through deep familiarity with regional safety standards and efficient global shipping routes.
For EU markets, our garments are manufactured to meet CE EN 343 standards, which govern protective clothing against rain, wind, and cold. For North American clients, we ensure compliance with all FTC labeling requirements and Flammability Standards. By working closely with recognized third-party agencies such as SGS and TÜV, we provide complete, auditable test reports for customs clearance.
Additionally, our logistics team coordinates sea, air, and multimodal freight networks. From handling customs declarations in China to securing ocean freight space with top-tier carriers, we ensure your bulk shipments move smoothly from our Xiamen facility straight to your regional distribution centers.
