Now you rep SUM even when you're not at a living history event! We originally had some of these made for us to wear at shows and events where we didn't need to be period dressed. Turns out others like them too, so we are offering them for sale here! These shirts are made from 52% cotton and 48% polyester, and are "Canvas" brand shirts that are very comfortable and well fitting. They do run a tad small, so I suggest you order a size larger than you normally wear (i.e. I'm normally a XL t shirt guy and wear a XXL in this shirt). The shirts are blue heather with vintage/distressed tan printing, for that vintage historic look. In stock sizes are listed.
