Patti Muscle Tank in Optic WhiteSold exclusively in our Portland, ME + Portsmouth, NH locations & not available for in store pickup in Kennebunk, Maine. Nation LTD gives us a muscle tank, but made it feminine. With a ribbed, crew neckline and over the shoulder short sleeves, it's made from a heavyweight cotton slub for a bit of structure. It's perfect on its own and so easy to layer, we bet you'll be reaching for this basic year round. NATION LTD. Optic White Tank, subtle shoulder
