    rethinking migraine relief.
    one soft cap at a time.

    Relief that treats flare days the way they actually happen: in the dark, mid-meeting, at 3am, with a toddler asking for a snack.

    Because ice packs slip, pills take an hour, and most cooling caps smell like a chemistry set. The Arctic Cap rethinks all of it: 360° ice crystal filling designed to be low-scent, gentle compression, and a slide-up eye mask so one cap covers every kind of bad head day.

    ONE CAP. TWO MODES.

    cold for the migraine, warm for the tension.

    COLD MODE · FROM THE FREEZER

    for the migraine

    Deep, even cold across your whole head the moment you need it. Freezer-ready overnight; stays cold long enough to matter.

    WARM MODE · FROM THE MICROWAVE

    for the tension

    Warmth loosens tight neck & scalp muscles and lets the day go. Microwave in 10-second intervals (max 30 seconds). Always test on your wrist before applying.

    THE FLARE-DAY RITUAL

    relief you don't have to think about.

    01

    it lives in the freezer

    Always chilled, always ready. No pill bottle to find, no messy dripping ice in a tea towel.

    02

    pull it on, one motion

    Slide the mask down for total blackout, or keep it up and stay at your desk, on your phone, with family.

    03

    lie back

    360° ice crystal filling wraps your temples, forehead, sinuses, and base of skull simultaneously.

    The slide-up eye mask means one cap does both: total darkness when the world is too loud, and cold-on-the-temples relief when dinner still has to happen.

    THE GIFT · TO BE LOVED IS TO BE SEEN

    when "feel better" isn't enough.

    You can't take their migraine away. You can hand them something that says you believe how bad it gets. One blue, one pink; one for the freezer, one for the microwave.
