How It Works

Slide your phone into the Thermal Phone Sleeve® before you head out. The insulated lining traps your phone's natural heat and blocks wind chill — keeping the battery in the temperature range it needs to keep firing. No charging, no cables, no setup. Pull it out when you need it, slide it back in when you don't. That's it.

"I already had a power bank. Still died at 38%. Spent 45 minutes sorting out the group at the lodge. Haven't thought about my battery once since I got this."

    FAQs

    Why does my phone shut off in the cold even when it still has battery?

    Lithium batteries slow down in freezing temperatures. When your phone suddenly needs power (camera, GPS, brightness), it can’t deliver it fast enough — so the device shuts down even if it shows 30–50% battery remaining.

    Our thermal sleeve protects the battery temperature so your phone stays stable and usable longer.

    Is it easy to use with gloves on?

    Yes.

    The sleeve is designed for quick access even with gloves on, so you can pull your phone out easily for photos, maps, or lift tickets without fumbling in the cold. It keeps your phone protected while still making it fast to grab when you need it.

    Does the technology actually extend battery life?

    Yes.

    Thanks to the NASA-inspired thermal barrier technology, by reducing rapid heat loss in freezing conditions, it helps prevent the battery from entering cold-triggered shutdown — so your phone stays usable longer on the mountain.

    Will it block signal, GPS, or Bluetooth?

    No.

    The sleeve is designed to protect temperature without blocking connectivity, so your phone still works normally for calls, maps, lift apps, music, and tracking.

    Will it fit my phone?

    Yes.

    The sleeve fits most modern smartphones including iPhone and Android models, even with a standard protective case.

    Do I really need this if I only ski occasionally?

    Even occasional riders run into the same problem: phones shutting off on chairlifts or when you need maps, tickets, or to meet friends.

    This simply removes that variable — so your phone works when you actually need it.
