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.

    comfortable and fit well

    Fits so well you forget you are wearing an undershirt. Very lightweight.

    Got my first three about six months ago, and have loved them ever since. The fit in the shoulders is incredible (I am a performing musician, and my arms are in constant motion, yet there is no constriction or binding). I also really like the side panels, and the depth of the v-neck is enough to stay hidden, especially under my summer polo tops.
