The SUMI tee is built on a Gildan 5000 heavyweight cotton blank — a classic unisex fit that has been the workhorse of screen-printed tees for decades. It runs true to a US size chart, with a square cut through the body and a seamless double-needle collar.
Body measurements taken flat, then doubled for chest. Tolerance ±1.3 cm. These are the garment dimensions — see how to measure for converting your own body to a size.

You need a soft tape measure and ideally a tee that already fits you well — we recommend measuring the existing tee flat rather than your body, then matching to the chart above.
Following the care guide keeps the print sharp and the cotton from shrinking past the size you ordered. Heat is the enemy of both — hot wash, hot dry, or a hot iron on the print will all shorten the garment’s life.
