“I gifted my cousin this vest. She is still slim from her cancer treatments and told me she is always cold. She lives in Colorado so winters can be rough. She wears her vest inside and outside and loves it so much. Her friends all want one. We chose medium which is just right for her 110 lbs. so be aware to size up.”
“Works amazing! Fit is good. I'm 5'4" 120 lbs and ordered the XS. I've ordered 3 others for people and all loved them! Only complaint is if you drain the battery (forget to turn it off) it can take a very long time recharge.”
