The Cool Cap is cleverly designed to fit within most hats, caps, head wraps and trendy beanies to deliver even, all-over head cooling relief. It’s made with a specially formulated plant-based cooling phase material (PCM) that is skin-safe and soothing and may be used to relieve heat stress, headaches, migraines, fevers or help with hair loss. *Cap not included. Shown for demonstration purposes only. Available in two temps:
  • 58° Chill (designed for cool therapy and relief; re-cools in the refrigerator)
  • 80° Go (designed for cool comfort and travels well; re-cools at room temperature).
Both temperature options stay cool for 20-40 minutes, depending on ambient temperatures. They re-cool in 20-30 minutes. Cool Solutions and Uses:
  • Heat Stress and Heat Exhaustion – head cooling helps prevent and mitigate heat stress and fatigue (58° or 80°)
  • Hyperthermia (abnormally high body temperature) – head cooling has been scientifically proven to substantially reduce the negative effect of hyperthermia on human brain activity as well as thermal sensation (58° or 80°)
  • Headaches and Migraines - research shows head cooling therapy helps reduce inflammation, stress and tension; calm the nervous system; and relaxes the muscles (58°)
  • Hair Loss from Chemotherapy - many oncologists recommend cooling caps during and after chemo treatment sessions as it is scientifically proven to reduce the amount of hair loss (58°)
