Favorite Piece of clothing

Not much else to say beyond the title. This is my second Flume, first crewneck, but the Flume shirt in any variety is literally my favorite piece of clothing I own. Super comfortable, versatile, stretchy yet fitting, never smells, can be layered with anything.

I need one of every color.
