Outlast® Thermoregulating Technology:

3
TEMPERATURE REGULATING FABRIC – OUTLAST® THERMO-TECHNOLOGY REDUCES SWEAT PRODUCTION
Advanced Heat Buffering: Outlast® technology uses microencapsulated natural wax that captures and stores body heat, creating a natural heat buffer to prevent overheating and excessive sweat production.

Pre-Sweat Regulation: Unlike conventional systems that manage sweat after it forms, Outlast® starts regulating temperature before moisture develops, reducing sweat production by up to 48%, according to independent studies.

Dynamic Temperature Management: When body temperature decreases, stored heat is gradually released from the material, maintaining a consistent and comfortable climate for the wearer.

Comfort in Fluctuating Conditions: Outlast® ensures a balanced climate for wearers, even in environments with changing external temperatures, enhancing comfort and performance.

Sweat Less, Perform More: The outlast-treated fabric reduces overheating and sweat by proactively managing your body temperature.
