Side effects. They may occur after a bit of turkey during a U.S. Thanksgiving holiday. Most of us know that turkey contains sizeable amounts of tryptophan, which will knock you into naptime... maybe against your will. This shirt will remind you and anyone around to tread lightly toward that good meal, because this shirt is printed on a very comfortable poly/cotton blended tee, and will only enhance the experience of couch napping. Available in a heather brown unisex crewneck for starters, but also in a flattering heather grey v-neck for the lady-girls out there. Check out our sizing charts for the right fit. Dig in.
