Heats up nicely
This heated vest has been incredibly useful for keeping warm during cold soccer games. It's easy to turn on with a button on the chest that also lights up to indicate the selected setting. The battery fits in a small pocket on the inside, and although it adds some weight, it's manageable. The vest provides warmth without becoming overly hot, especially when worn under a coat. The fabric isn't too thick, and I appreciate the diamond stitching.
