These "sweaters" have a Sonic 3 theme & lots of different fun pixel designs...but are they really sweaters, or are they sweat shirts? A sweater is something woven out of big fibers (ex. yarn) that you can see, often with texture of some kind too, while a sweatshirt has a smooth exterior & usually fuzzy interior. It comes in a mens' or ladies fit (Though they don't look much different) & are adult sizes only. Look at the nice variety of designs they use: a ring, Knuckles who is laughing, standing, gliding, running, Tails who is running, spin jumping, flying, standing Sonic who is rolling, standing, waiting/tapping & dieing (yeah...) Eggman who is laughing/standing, in Egg o matic, frazzling?, running, and then a star bumper, crab meat, chop chop & buzz bomber. With 4 sprites for everybody, plus a batch of badniks, it makes this design pretty busy too. These are 39.99 pound each, which seems rather steep for a long sleeve shirt. This is a 2014 item.
