No matter how much styles in men's underwear change, the short sleeved crew neck t-shirt will always be a classic. With its signature rounded, banded neck, the crewneck works as both underwear and as a stand-alone, perfect under clothing, alone as a casual shirt and even for workouts. And while every man should have some classic cut white T-shirts on hand, there are many more styles and cuts to choose from.
Cotton is a good choice in undershirts, with its moisture-wicking properties and durable soft feel. For a smooth, body-hugging fit, look for undershirts made of a combination of cotton and spandex with a lean silhouette and and narrow sleeves. Performance crews are great for sports and workouts, made of high-tech fabrics that keep you cool and dry and an ergonomic cut that moves with you. There are also crew neck tee shirts with extra length, guaranteed to stay tucked in. Undershirts are such a wardrobe necessity, that many brands offer them in multi-packs, either all the same color or in a variety. Multi-packs cut down on shopping time and insure you'll always have a clean shirt at hand.
