How we measure
- Chest: laid flat, measured across one inch below the armhole. Double it for the full circumference.
- Body length: highest point of the shoulder, straight down to the hem.
- Sleeve: center back of the collar, along the shoulder, to the sleeve hem.
Between sizes?
Our tees are a 7.5 oz heavyweight, so they sit with more structure than a standard tee and drape rather than cling. They still run true to size. Size up if you want a looser, longer body. The crewnecks already sit relaxed, so most people stay with their usual size.
