Proton Hat

Everything you love about our Proton hoodies and jackets – warmth, breathability, weather resistance, stretch – in a hat. Made for anything winter offers, it shines during high output in cold conditions. The air-permeable Fortius™ Air 20 fabric balances airflow and wind resistance. Made with wicking fibres, Octa® Loft knit insulation is warm, breathable, and exceptionally soft. Insulated flaps warm the ears and tuck out of the way when not in use.
