Size conversion chart - Men's
Not sure about your size?
Our sizing is based on a UK grading system so please check your chest size. Measure your chest with arms straight at sides, around the fullest part, close under the arms.
Men's undershirts are designed to fit but not be tight. The 5% Spandex gives the fabric a 20% stretch so our undershirts fit most shapes. If you prefer a looser fit choose one size up to allow the undershirt to hang rather than fit.
If you are unsure about your size we are here to help you. Send an email to firstname.lastname@example.org and we'll find the ideal size for you.
