- WARMTH WHERE IT COUNTS - Heat stays on your core, so a windy walk feels different from standing inside a coat that only traps what your body already made.
- THREE HEAT SETTINGS - Move between low, medium, and high with one chest button when the wind picks up or you start moving.
- SLIM LAYER FIT - The flexible cut wears alone or under a jacket without the stuffed, stiff feeling of a heavy coat.
- YOUR POWER BANK - It runs on a standard 5V power bank, so you are not locked into one proprietary battery.
- TOUGH OUTER FABRIC - Tear resistant, water resistant material handles wind, light moisture, and days that ruin a thin layer.
