This shirt gives a whole new meaning to collecting fireflies. Trapped inside of jar is the Firefly-class transport vessel, Serenity. Captained by Malcolm Reynolds, many would love to get their hands on the ship and her crew. Lucky for them, you got to Serenity first and bottled her up for safe keeping. The design is inspired by Joss Whedon's Firefly and set against a 100% cotton army green t-shirt.
