“Gives wearer a broader comfort range of external temperature variance, as well as adjustability for internal body temperature variations throughout the day based on your activity level. This eliminates the need to change or add/remove layers. Most versatile piece of clothing i own. Very comfortable material, seems durable. Robust electronics and controller. Fit is true to size. Would recommend to anyone.”
“My husband loves the vest. It's versatile enough he can wear it under a heavy coat when shoveling snow or on its own in a cooler office building. He said the placement of the battery pack is excellent because it is out of the way. He wears a size medium in almost everything, and the medium vest fit him perfectly so it is true to size. He's only had it for a few days so far, so I cannot comment as to longevity.”
