If you are new to sourcing functional fabrics, you have likely seen claims like '30,000mm waterproof' or '20,000 g/m²/24h breathable' but do you know what those numbers really mean? This article breaks down the key functional fabric tests—waterproof, breathable, UV protection, antibacterial—with the official standards (AATCC, ISO, ASTM), common grading levels, and the traps that catch inexperienced buyers. Learn which tests matter for your product, which numbers are marketing fluff, and how to avoid costly specification mistakes.

No fluff, just real-world knowledge from someone who's been on both the supplier and buyer side.
