Quanzhou Xinheng Outdoor Equipment Co., Ltd.

Quanzhou Xinheng Outdoor Equipment Co., Ltd. is one of China's leading waterproof bag and soft cooler manufacturers, with over 30 years of specialised manufacturing experience since its establishment in 1992. Operating under the XINHENG and ONOBO brand names, the company is headquartered in Fengze District, Quanzhou City, Fujian Province — a recognised hub for outdoor and sporting goods manufacturing in China. Xinheng exports to more than 16 countries including Australia, the USA, Germany, Japan, the UK, and Brazil, and consistently reports annual turnover exceeding USD 25 million, cementing its position as a major force in the global waterproof bag market. The company's 30,000-square-metre facility employs over 400 skilled workers supported by a highly automated production line. Key equipment includes 160+ high-frequency welding machines, computer stitching machines, hydraulic pressure cutting machines, and laser cutting machines. Rather than relying on traditional sewing methods, Xinheng uses proprietary welding technology to create fully waterproof and airtight seams — a technique backed by 20 utility model patents and 6 design patents. This manufacturing capability supports a daily output of up to 4,000 soft cooler bags, with annual capacity reaching approximately 1 million cooler bags or 1.5 million welded bag units. Xinheng's product range is extensive and purpose-built for the outdoor and adventure market. Core lines include waterproof rolltop backpacks, bicycle and motorcycle bags, soft cooler bags (maintaining a temperature differential of ≤10°C for up to 72 hours without electricity), airtight backpacks with an IPX7 waterproof rating, waterproof fishing and duffle bags, inflatable SUP boards, inflatable kayaks, and PVC inflatable camping tents. The company also manufactures under OEM and ODM arrangements for major global brands including RTIC, Costco Wholesale, Billabong, Quiksilver, Engel, Karrimor, and Dometic — providing clear evidence of their capacity to meet international quality and compliance standards. Quality assurance is embedded across the entire production process. Xinheng holds ISO9001 quality management certification and has passed BSCI, Costco, and Boardriders social compliance audits. Their waterproof and airtight backpack enterprise standard has been officially certified by the Quanzhou City and Fujian Province Technical Supervision Bureau. Standard MOQs begin at 1,000 pieces (with trial orders accepted at lower quantities), production lead times run 40–45 days, and the company supports both OEM and custom design services with an in-house design team.
