MEN’S TONAL SCULPTING UNDERSHIRT

TONAL GRAY · BUILT TO STAY DISCREET

Smooth the Belly and Chest and Stay Discreet Under Your Shirt

Targeted compression visually smooths belly, chest, and side fullness while worn, helping dress shirts, polos, and tees fall over a cleaner-looking torso. Tonal gray zones and a low-profile V-neck keep the shaping layer discreet beneath lighter clothing.

Questions, answered

Is it visible under clothing?

Low-profile seams and tonal finishes are designed to sit beneath shirts, polos and tees. Visibility can vary with fabric weight, fit and color.

What visual effect should I expect?

Targeted compression visually smooths the midsection while you wear it. It does not change body weight or measurements, and the effect ends when you take it off.

How should the compression feel?

Close and supportive, designed for a comfortable, flexible feel. Flexible stretch fabric moves with you through the day.

How do I choose my size?

Use the size guide on this page. If you are between sizes, choose the larger size for a more comfortable fit.

What if the size is not right?

Contact hello@defynmen.com within 30 days of delivery. Items must be unworn and meet the eligibility requirements in the Return Policy.

How should I care for it?
