Combining the warmth of insulation with the breathability of fabric, PRIMALOFT® Active Evolve Insulation adapts to your level of effort to keep you warm and comfortable without overheating. Woven fibers trap air and provide protection when you need it, but when your body temperature rises, heat and moisture can easily escape. Whether it’s zone 2, low intensity exercise or you’re pushing your limits, this adaptive, low-bulk insulation evolves to meet your changing needs.
INSULATION THAT ADAPTS TO YOUR EFFORT
PRIMALOFT® Active Evolve Insulation works smarter when you work harder so you never overheat, even when pushing the limits.
