Was worried it would feel stiff but it’s pretty stretchy. Fits snug around my stomach and my shirts sit a bit better over it. Glad I checked the size chart first.

I was skeptical at first, but after using this for a month, I'm a true believer. The quality is outstanding!

Doesn’t make my belly disappear, but it does smooth things out under a t-shirt. That’s really all I wanted. The fit is tighter than a regular undershirt.

Frequently Asked Questions
How does CoreFit work?
+
CoreFit uses a snug compression fit around your chest and waist to create a smoother outline under clothing. The shaping effect is there while you wear it.
What size should I order?
+
Measure your chest and waist, then compare them with our size chart. CoreFit fits tighter than a regular undershirt, so don’t size down for extra compression.
Will it show under my shirt?
+
CoreFit is designed to sit close to your body for easy layering under tees, polos, and button-downs. How visible it is depends on your shirt’s thickness, colour, and fit.
Does it feel tight?
+
Yes-expect a snug, supportive fit, especially when putting it on. The fabric stretches with you, but it shouldn’t feel painful or restrict your movement. If it does, remove it and check your sizing.
Can I mix colours and sizes in the two-pack?
+
Yes! Choose the colour and size for each tank separately. Get two of your favourite or choose one black and one white.
