Best product out there in this horrible situation, I have tried other amazon stuff for my active life style, to no avail, like the shooting jackets....puhhhh. From an LVAD wearer myself, this is the best you can get without having an LVAD at all. You can't see it from the front, and only a slight bulge in the back. I am very active as a Sr. Manufacturing Plant Engineer actively crawling around machines and this rarely ever causes me issues over the stuff the hospital gives you. Outside of work, woodworking, shooting guns, motorcycle riding, wife/girlfriend time!!!, you can't beat this breakthrough.
