Why Elite MTS sports underwear ? Sports underwear come in many different polyester qualities. Elite MTS contains 60% Dacron 107 Dupont and 40% Microfibre. We have chosen this fabric because of high moisture transportation, something that we believe is the most important aspect of sports underwear. The fabric is made of small fuzzy fibres which increases the underwears ability to transport moisture. One disadvantage with fuzzy fibres is that some pilling may occour. Elite MTS is the professional choice when you want maximum comfort and moisture transport 300% Elasticity to get the best fit. It is not without reason that athletes choose this model as their favorite. Push yourself to the limit, and let Elite MTS sure to keep you dry and warm.
