Assos could have given their newest short sleeve baselayer a simpler name, but we have to agree that the SS. skinFoilSummers7 Body Insulator tells you everything you need to know about itself, once you've broken it down a little bit. Allow us to help: SkinFoil is Assos' name for its body hugging, temperature regulating baselayers, which are constructed with no visible seams to eliminate chafing and enhance mobility. A blend of nylon and polyester moves moisture quickly away from your skin, and the compressive fit helps support muscles to decrease fatigue. SS stands for, reasonably, short sleeve, which you probably don't need explained, and Summer denotes not even kidding the seasons in which the midweight skinFoil is designed to excel. Finally, s7 indicates that the skinFoil is part of Assos newest line, which takes the already legendary Assos ethos to the next level.
