St. John's Bay Temp Flex Pants
Our Temp Flex Pants combine innovative stretch fabric with climate-adaptive comfort technology, making them the perfect choice for year-round wear. The Temp Flex system actively responds to your body temperature, keeping you cool in warm conditions and comfortable when temps drop.
The proprietary Temp Flex system uses phase-change materials embedded in the fabric structure to actively regulate your body temperature. When you're warm, these microscopic capsules absorb excess heat; when you cool down, they release it back gradually. This creates a consistent comfort zone that adapts to your activity level and environment.
