Dongguan Lianyi Sport Goods Co., Ltd., operating under the brand Lianyi Bags, is a Neoprene Specialist and Multi-Material Custom Bag Manufacturer located in Dongguan, Guangdong, China.
Established in 2007, we provide OEM and ODM manufacturing services for global brands, importers, wholesalers, promotional companies, retailers and product developers. With more than 19 years of custom manufacturing experience, we combine specialized neoprene expertise with flexible multi-material bag production to help customers develop different product lines through one reliable manufacturing partner.

Neoprene has been one of Lianyi’s core materials since the beginning of our manufacturing journey. Our team understands how neoprene thickness, density, elasticity, surface fabric, lamination structure and production methods affect the appearance, protection, insulation and durability of a finished product.

We manufacture a wide range of custom neoprene bags and accessories, including laptop sleeves, bottle and can sleeves, cooler bags, cosmetic bags, sports covers, protective pouches and other soft goods.

One of our signature capabilities is laminated neoprene development. We can combine neoprene with polyester, nylon, velvet, mesh and other surface fabrics to create different textures, colors, printing effects and functional performance. This allows buyers to develop products with better appearance, hand feel, protection, insulation, structural stability and brand presentation.

While neoprene remains an important part of our expertise, Lianyi is not limited to one material.
We also manufacture custom bags using polyester, nylon, puffy fabric, quilted fabric, velvet, canvas, TPU, PU-coated materials, PEVA, aluminum foil and other functional textiles and linings.
Different materials are suitable for different markets, product structures, price levels and performance requirements. Our team can recommend suitable material combinations according to the intended application, target customer, expected appearance, required function and project budget.
This multi-material capability allows customers to develop several product categories without managing multiple factories.

Lianyi supports a broad range of custom soft bags and accessories, including:
• Cooler bags and insulated bags
• Laptop sleeves and protective cases
• Cosmetic bags and travel organizers
• Wine, bottle, can and cup sleeves
• Pickleball paddle covers and sports bags
• Tote bags, handbags and crossbody bags
• Backpacks and cooler backpacks
• Puffy bags and quilted accessories
• Neoprene pouches and protective sleeves
• Other customized soft bags and accessories
For buyers developing multiple collections, working with one manufacturing partner can reduce repeated communication, improve consistency and simplify supplier management.
