    How to choose my size?

    We recommend using the size guide (located next to the size options) on the product page to find your perfect size by comparing it to your body measurements. If you need further assistance, please contact us at

    Can I wear it on the plane or put it in carry-on bags?

    Sure, you can wear it on the plane. All ororo heated apparel is TSA-friendly. All ororo batteries are lithium batteries and you must keep them in your carry-on luggage.

    Will the heated apparel work at temperatures below 32℉/0℃?

    Yes, it will still work well. However, if you’re going to spend a lot of time in sub-zero temperatures, we recommend you purchase a spare battery so you don’t run out of heat!
