Engineered for the active professional. The UNDR Men's Core Support Compression Vest Tank Top delivers targeted engagement to the chest and core without restricting upper body mobility.
Crafted from a lightweight, breathable 80% nylon blend, it functions as a second skin. Its thin construction makes it ideal for year-round wear, providing a firm hold that naturally encourages better posture whether you are at the desk or on the move. Seamless styling ensures it disappears completely under a dress shirt or polo.
Available in Black, White.

“Flew 14 hours to New York. Zero swelling in my feet. Best travel purchase this year.”
“Keeps the cold out and my back straight. Good stuff and hugs my little big friend tight.”
“Velikost M sem moral zamenjati za L, ker mi je bila okoli prsi preveč tesna. Vračilo je bilo sicer preprosto. Velikost L mi odlično pristoji in pod delovnimi srajcami opravlja točno tisto, kar potrebujem. 👍”
