Wear it in 3 Steps
-
Step 1. Hook In, Zip Up
Start with the inner hooks for base compression, then zip it up for full control and support.
-
Step 2: Wear It Anywhere
Under gym gear, polos, or dress shirts — it stays discreet and smooth all day long.
-
Step 3: Let It Work for You
Chest looks tighter. Waist feels firmer. Posture improves. Confidence kicks in.
Now that you know how easy it is… let’s answer a few common questions.
Does it really shape your chest and stomach?
Yes — it targets the chest, belly, and waist with high-compression fabric and an adjustable fit that stays in place.
What’s it made of?
It’s crafted from 90% polyester + 10% spandex — durable, stretchy, and breathable. Available in black, beige, and white.
Will it help with posture too?
Definitely. The X-cross back design and firm core support help straighten your shoulders and align your spine.
Is it hard to take on and off?
Not at all. The hook-and-zip design makes it quick and easy — no more squeezing into tight pullovers.
Can I wear it all day?
Absolutely. It’s built for comfort and designed to disappear under your clothes — no rolling, bunching, or overheating.
What if it doesn’t work for me?
You’re protected by a 30-day guarantee. If you don’t feel a difference — or just change your mind — get in touch and we will make it right.
