The Lululemon men’s metal vent tech exercise short sleeve is great because it’s fusion of common sense and out there thinking.  As you can see in the photo, there are strange patterns on the lower chest and back of the shirt.  These are actually dense mesh patches with small perforations that allow these parts of the shirt to breathe better since these are areas a high sweat.  The shirt also features mesh holes in the armpits for added ventilations.

On top of the “low-tech” cooling system, the shirts materials include silver thread blended into the technical polyester which prevents bacteria from growing in the material, thus preventing odors from accumulating over time.
