Thermos and Threadless teamed up to create a fun line of lunchboxes and thermos bottles. I wanted to buy the spaceman bottle above for my son, but this style is only available in the 24 ounce size (as opposed to the 18 ounce) and that's a bit bulky for a 4-year-old to bring to school every day. So instead, I got him the t-shirt of this same fantastic graphic titled "Funkalicious," by Christopher Golebiowski. There are more than a dozen designs in the Thermos+Threadless series.
