FORTIS™ Compression Tank — Men's Body Shaper & Posture Tank
The everyday frustrations FORTIS was built to fix
If you've ever changed your shirt three times before leaving the house, you're not alone. These are the real problems — and exactly what FORTIS solves.
You reach or sit, your shirt rides up, and suddenly your stomach and back are showing.
Stays tucked, no exposure. The extra-long cut tucks deep and stays put — smooth fabric underneath, never bare skin.
Your chest looks soft or puffy ("gyno") and shows through fitted shirts.
Flattens the chest. Targeted upper-body compression smooths and firms so your shirt lies flat.
Love handles and a muffin top spill over your waistband.
Tucks in the sides. Firm 360° midsection compression for a straight, streamlined waist.
Your gut pokes out and strains your shirt buttons.
Holds everything in. Double-layered compression flattens the stomach for a slimmer profile.
Rolls and bulges show right through a plain t-shirt.
Smooths the surface. One even, sculpted layer so your outerwear drapes cleanly.
You avoid tucking in or wearing anything fitted.
Dress how you want. Tuck in, wear fitted shirts, and move through your day without a thought.

Bought it because I was sick of constantly pulling my shirt down to cover my stomach. Now it stays tucked and nothing shows when I reach or sit. Honestly the best $45 I've spent.
Bought these for my husband and he loves them. They fit well and make him look better in his clothes. We'll be ordering more!
I use these as undershirts and they keep me cool all day. 100% confidence boost. Long enough to tuck in and shape my belly.
