You Didn't Fail.
You Were Fixing the Wrong Problem.
Your belly looks bigger than it is. It always has.
Trainers have known it for years: when your posture collapses, your stomach pushes forward. The same belly can look two sizes bigger — just from how you carry it.
That's why the gym alone never fixed how you look in shirts. That's why sucking it in never lasts. You were working on the surface of a problem that starts with your frame.
The CoreForm's SHAPESTAND™ zones hold your torso firm and pull your shoulders back with every hour you wear it. Not for 20 minutes. For the whole day you're actually living.

Who is CoreForm designed for?
Any guy who wants his shirts to fit cleaner, his posture straighter and his silhouette sharper — whether you're 30 or 70, training five days a week or just getting back into it.
How does the CoreForm tank actually work?
SHAPESTAND™ zoned compression: three knit densities mapped to your torso. A firm panel holds chest and stomach flat, a smoothing weave locks the sides, and an upper-back tension band keeps your shoulders pulled back — all day, automatically.
How quickly will I notice results?
The shape difference is immediate — that's mechanical, not marketing. The posture habit builds over the first two to three weeks of daily wear.
What happens if my size doesn't fit?
Email us at support@tryslova.com — size exchanges are free, and a real person answers within 24h.
How long does shipping take?
Orders ship within 24h and typically arrive within 4 to 7 business days, tracked.
Can I throw my CoreForm in the washing machine?
Absolutely — cold gentle cycle to preserve the compression, hang dry.
What is the CoreForm made of?
80% nylon, 20% spandex.
