Phase-change materials (PCM) and polyethylene cooling fibers pull heat away on initial skin contact for the first 15–20 minutes as you fall asleep. Sustained all-night temperature regulation requires a ventilated core—such as Purple's GelFlex Grid, pin-core Talalay latex, or shredded cross-cut foam—so warm air can escape instead of pooling beneath your neck.
