Captain Sperm, a sperm whale, debuted this spring. This summer we made it into a T-shirt. This loose-fitting T-shirt is made from thick, firm Tenjiku fabric, knitted with air-spun yarn, which has a rough, dry feel. The men's T-shirt is printed on the back, but the women's T-shirt is printed on the front, so we recommend pairing it with a jacket to show off the print.
