Expert Advice

Comfort is essential in your underwear. Look for the features in your garment that ensure you feel your best, from beginning to end of your day. Men's underwear and boxer fabrics should always be lightweight and soft-to-the-touch.

Moisture-wicking technology in your underwear works to keep you fresh where you need it most, pulling perspiration away from your skin and the garment for a dry feeling that lasts all day. Look for flatlock seams, which minimize chafing and amplify comfort. A flexible, stretchable waistband delivers a snug, comfortable fit. Ventilation zones on your underwear allow proper airflow.

Ensure your undergarment doesn't stand in your way: In athletic cups, jock straps and supportive gear, look for an ergonomic fit that contours to your body, providing the precise blend of protection and breathable feel. Ventilation and mesh paneling allow maximum airflow.

Your comfort begins with your undershirt. Go for a tag-less T-shirt for a seamless feel beneath your clothing. Moisture-wicking technology in your shirt keeps you dry and comfortable, no matter what your day has in store. Always ensure your tee delivers a soft, light feel. For extra style choose a V-neck tee.

In men's underwear, undershirts and baselayers, look for antimicrobial finish, which prevents the growth of odor-causing bacteria.
