When sourcing gloves on Alibaba.com, two features dominate buyer inquiries: breathability and waterproofing. These attributes are not mutually exclusive, but achieving both requires sophisticated membrane technology. Understanding how these features work—and their trade-offs—is essential for B2B buyers making bulk purchasing decisions.
Breathability refers to a material's ability to allow water vapor (sweat) to escape from inside the glove to the external environment. This is measured in grams per square meter per 24 hours (g/m²/24h). Higher breathability ratings mean better moisture management, reducing hand fatigue and skin irritation during extended wear.
Waterproofing indicates the glove's ability to prevent liquid water from penetrating from the outside. This is typically tested using hydrostatic head pressure (mm H₂O) or immersion tests. True waterproof gloves must withstand sustained exposure to water without leakage—critical for medical examinations, food processing, outdoor work in wet conditions, and winter sports.
Other common membrane technologies include ePTFE (expanded Polytetrafluoroethylene), which offers excellent waterproof-breathable balance but at higher cost, and polyurethane (PU) coatings, which provide good waterproofing with moderate breathability at lower price points. Material selection depends on target application, price sensitivity, and performance requirements.
