How to measure yourself
- A – Length: same as the product. Place the tape at the top of your shoulder and measure down to where you want the shirt to end.
- B – Chest: measure around the fullest part of your chest. Keep the tape horizontal. This is the measurement to compare with the Chest column in the table.
- C – Sleeve: from centre back of your collar, over the shoulder, down the outside of the arm to your wrist.
When in doubt, size up. The Gildan 5000 is a standard unisex fit. If you are between sizes or prefer a looser fit, go one size up. Cotton may shrink slightly on the first wash in hot water - always wash cold.
