Say goodbye to the days of boxy, sweat-absorbing, easily-untucked, single-purpose undershirts. All Citizens AirWeight Undershirts are weightless undershirts for men powered by our custom built Re:Luxe performance microfiber that’s light on the planet but heavy on performance: eco-friendly, wrinkle-resistant, luxuriously soft, durable, anti-odor, breathable, sweat-wicking, quick-drying, stretchy and anti-chafing. 

It stays hidden under dress shirts, protects dress shirts from sweat stains, offers exceptional ventilation and runs longer in the back to stay tucked even after hours of movement. The form-fitting cut allows for seamless layering. High performance fabric + smart features = the perfect undershirt for travel, commute and beyond. 

Available in Bright White and Stealth Gray. Although counter-intuitive, gray’s low-contrast shade absorbs and reflects similar light waves that all skin colors do, giving it much better invisibility than other colors such as white - our Stealth Gray is the perfect undershirt color to stay hidden.

All of our garments are easy care: wash on cold and hang to dry - that's it
No ironing necessary, but if desired, set the iron to very low heat and place a towel between the iron and the shirt. Do not let the fabric come into direct contact with the iron. 
Do not dry clean 
Do not bleach

So easy, you won't need to call mom for help. 
She'll be so proud.
