Undershirts act as a defensive layer between your body and dress shirt by managing sweat and preventing under arms from yellowing. We brought our penchant for comfort and performance to the AirWeight Undershirt by designing a base layer that's suited for the office but can handle a wide range of activities such as cycling and running. The signature mesh Breathe Zone side panels provide exceptional ventilation to keep you cool in the war room, while the moisture-wicking, quick-drying performance microfiber handles sweat. The AirWeight Undershirt is cut to be form fitting for better layering and runs longer in the back to stay tucked even after hours of movement. Say goodbye to the days of boxy, sweat-absorbing, easily-untucked, single-purpose undershirts.

        BEST undershirt ever!!

        It's likely the most comfortable thing next to my skin. I'm finding I'm wearing one every day, not just under dress shirts. It sops up sweat quickly and the seams don't show under shirts. Buying a bunch more now!

        The magical unicorn undershirt

        I have been hunting high and low, over hill and dale for the perfect under dress shirts undershirt with a deep enough neckline so that you can undo the two buttons at the top Of your dress shirt. I saw your site and thought, ‚Äú heck let‚Äôs try that one, too.‚ÄĚ Omg, the fabric is so comfortable and soft. I would say that you feel like you‚Äôre not wearing anything but it‚Äôs way better than not wearing anything. If feels so good on the skin I want to wear it now underneath anything, even other T-shirts and sweaters. Kudos and send me some more!
