Works as described, I have only used it in 40 degree weather and it kept me warm. Easy to inflate and deflate, the Velcro strips do not line up evenly front to back. The Velcro is higher in the front than on the back. Don't have any idea why that is. No complaints, works well to keep torso warm, I will use it again when the weather gets cold for hiking and cycle riding. I hardly know it is on me, very comfortable.
