HaiLan runs a cap knowledge site and supports brand/team custom baseball caps as a source factory (OEM/ODM). We publish the information needed for selection, sampling, and quoting.
HaiLan is a custom baseball cap manufacturer and content maintainer, located in the beautiful city of Qingdao, China. The site focuses on materials, crafts, and style comparisons plus a custom inquiry entry, helping buyers and designers communicate sampling and mass production in the same language.
Public knowledge: fabric performance, logo craft trade-offs, crown/brim choices. Business: custom requests, material/craft combinations, sampling and production details (lead times and pricing confirmed in writing).
Business email: HaiLan@hailango.com. Or use the homepage custom inquiry form — we reply on business days.
Topic pages grow with common sourcing questions. If something is unclear, email us and we will prioritize fixes.
