Engineered for extreme conditions, tactical operations, and premium water sports performance.
The global demand for high-grade professional dry suits has shifted from basic thermal barriers to complex, multi-laminate adaptive protection systems. As commercial marine applications, search and rescue operations, and extreme aquatic tourism increase, the technical standards for exposure suits are climbing. Modern dry suits must provide complete waterproof protection while actively promoting moisture vapor transmission to prevent heat exhaustion during heavy activity.
Sustainable manufacturing is another major force reshaping the industry. Global enterprises now mandate PFC-free DWR (Durable Water Repellent) coatings and recycled membrane materials. Brands are also demanding modular custom designs that feature replaceable seals (latex, neoprene, and silicone) to extend product life cycles. Manufacturers who fail to adopt these material innovations are quickly losing market share.
How Xiamen Yuelei Sports Co., Ltd. builds production stability in a volatile global market.
By shifting from retail sourcing on AliExpress in 2021 to our own workshop under the LKVER brand, we gained direct control over fabric sourcing, cutting, and pressure testing. This prevents external production delays.
Our 1,600㎡ facility is staffed by 30 highly trained professionals. Every single dry suit goes through intense hydrostatic pressure tests to ensure all heat-welded seams are 100% waterproof before packing.
We build tailor-made solutions for corporate clients. From zipper placements (front-diagonal, shoulder-zip, or relief zippers) to custom sizing and color schemes, our production lines easily adapt to your design requirements.
Founded on a commitment to quality and technical precision, we solve the major headaches of global B2B buyers. After facing supply chain delays from third-party manufacturers in 2021, we set up our own specialized factory. Today, we run two international Alibaba platforms and an AliExpress flagship store, serving commercial clients worldwide.
Our facility runs high-precision hot-air welding equipment, ultrasonic bonding machines, and specialized electronic leak detectors. By keeping fabric testing, cutting, assembly, and sealing in-house, we deliver consistent quality that third-party sourcing agents simply cannot guarantee.
Understanding user intent: How different industries use our custom dry suits.
Public safety dive teams and coast guards require quick-entry systems, reflective panels, and reinforced knees and elbows. Our front-zip suits (like the DM-35 and DM-37) are engineered to let responders suit up fast under intense pressure.
Kayaking, rafting, and sailing require high mobility around the shoulders and waist. The DM-38 Side-Zip Whitewater Suit features optimized cuts that eliminate seam friction, giving athletes full range of motion.
Technicians working on offshore oil rigs or wind farms face harsh spray and freezing temperatures. Our high-durability multi-laminate dry suits protect workers from hypothermia during long shifts in open water.

B2B Procurement, Customization, & Product Care Insights
For custom OEM/ODM designs (including custom colors, specific pocket layouts, and logo printing), our MOQ starts at 50 units. For stock models under the LKVER brand, we can fulfill smaller sample or batch orders to help clients test their local market.
Every dry suit undergoes a rigorous pressure test before leaving our factory. We seal all entry points, inflate the suit to a set pressure, and spray it with a leak-detection solution. If any pressure drops or micro-bubbles appear, the suit is rejected. We also perform random hydrostatic head tests on our raw fabric rolls to check laminate bonding quality.
Yes. We offer UK-imported latex seals for maximum watertight protection, and highly elastic neoprene seals for warmer water or users who prioritize neck comfort. Silicone seals are also available as an option if you plan to install modular, user-replaceable seal ring systems.
We use genuine German YKK AquaSeal or TIZIP MasterSeal zippers. These polymer zippers are highly flexible, lightweight, and completely airtight. They resist corrosion from seawater far better than older brass zippers, reducing product returns and maintenance costs.
In 2021, a sudden spike in online orders caused supplier bottlenecks, and they could no longer meet our delivery times. To protect our brand reputation and ensure consistent shipping windows, we invested in our own 1,600㎡ workshop in Xiamen. This vertical integration allows us to keep our promises to retail and wholesale clients alike.
