BNWT Runs Small the vintage tanks in our personal archive were past threadbare... so, we made our own. for our warm weather go-to, we use a fine-ribbed cotton that's soft, but still sturdy and structured. the result re-creates the characteristics of dreamy vintage military-issue tanks from days gone by. patterned, cut, and sewn in the USA from premium American-made fabric. crafted with purpose, from fit design down to the smallest details. wear often, wash not so often. wash cold. tumble dry low. 97% cotton, 3% spandex
