Understood – the vertical "rib" seams on the abdomen are compression zones that, in the right light, suggest a more defined core. This is a visual/structural effect created by the fabric panels, not actual abdominal muscle sculpting – it is important to phrase it this way, otherwise we run into the same type of problem as with the "get rid of love handles" point earlier (promising a real physical change that the product does not deliver).

Revised description:

A sleeveless compression undershirt with structured shaping zones: The integrated compression strips on the abdominal area provide a visually more defined core directly on the skin – subtle under clothing, visible in the right light.

Why you need it:

• Structured compression zones – for a visually more defined core
• Sleeveless – fits under any top
• Breathable and quick-drying
• Slim fit – fits snugly without constriction

FAQ addition:
Are the compression zones visible under clothing? No, they are not visible under normal clothing – the defining effect is visible directly on the skin, e.g., while working out or at home.
