Regular fit polo's are mass market tees which are designed to fit as many people as possible. If you’re a muscular guy, you’ll probably have to size up on regular fit tees to fit your upper body. This means the tee will be too large and boxy around your waist and arms. Not very flattering.
Slim fit polo's are cut closer to the body to give a more modern and flattering shape. This may be slimmer across your body, however, they do not have room for larger muscles. Therefore they may be restrictive and too tight for athletes.
Muscle fit polo's are designed to flatter muscular physiques. They fit closely from the athletes upper body, all the way down to their waist, with a tapered fit on their arms. A true muscle fit will be better for guys with a large ‘drop’. Where their waist is considerably smaller than their chest and arm measurements.
Fitizen muscle polo's collection has a tailored fit for muscular guys, without a skin wrapped appearance or constrained feeling.
