Functional Second Skin
The undershirt is like a second skin. Because it has a light and thermodynamic fabric, it is almost imperceptible, although its effects will make all the difference in your daily life. Our fabric absorbs twice as much sweat as a cotton t-shirt and protects against odor, by blocking bacterial growth.
Thermodynamic technology helps regulate body temperature. The t-shirt fabric is highly breathable, retains sweat, and quickly evaporates it. If your shirts constantly have yellow deodorant stains under the armpits, our undershirt will prevent them to exist.
