What Is Hydrostatic Pressure Testing for Technical Sportswear Jackets?

Hydrostatic pressure testing measures a material's resistance to water penetration as water pressure increases under defined conditions.

It can support a jacket fabric's water-resistance specification, but it does not by itself establish that the complete garment is waterproof. Seams, zippers, openings, construction, and durability also matter. Agree the test method and acceptance requirement, then assess relevant finished-garment details before publishing a protection claim.
