This shirt was designed specifically for LVADs. This T-shirt is for the HeartMate LVAD Device only. SIZES RUN SMALL: Please order one size larger than you normally wear or use the adjusted size chart listed in our pictures. The HeartMate controller pocket features an elastic closure at the top to securely keep the controller in place. Battery pockets are positioned under the arms for comfort and a secure fit. Reinforced shoulder straps help distribute and absorb the weight of the batteries. Two loops on the front keep cables close to the body, safe, and out of sight. Designed to be worn under clothing, this shirt helps protect and conceal your LVAD. The controller pocket is made with a comfort pad close to the body and heat-dissipating material on the front to keep you cool. The shirt is made with moisture-wicking material to keep you cool, dry, and odor-free. It is stocked in sizes small through 3X. HeartWare LVADs require the separate purchase of the controller pack (item 1421). SIZES RUN SMALL: Please order one size larger than you normally wear or use the adjusted size chart listed in our pictures.
