What is a bubble vest?

Response:
A bubble vest is an outerwear piece of clothing worn by both men and women. Usually it is stuffed with down or some sort of insulation to make it nice and warm.  Also, the vest usually has seams in it to make the bubble like appearance. There are lots of different brands that make bubble vests, but some common ones are The North Face, L.L. Bean, Patagonia, and Lands’ End.
