In 2016 I received my LVAD at Banner – University Medical Center Tucson AZ. Since then I have been searching for the perfect bag to hold my LVAD controller, batteries and backup equipment that is affordable and comfortable. Finally I discovered this backpack. It has great padded straps, the exterior is water resistant, I am able to create unlimited designs on these bags. What has been the most fun is that I can make use of my artist and creative design background.
