Our size chart helps you find the perfect fit with accurate body measurements. Compare your chest, waist, and length to the guide for best results. If you're between sizes, we recommend choosing the larger size.
✔ No Rolling Waist
Stays flat and secure — no folding, no digging, no constant pulling down.
✔ No Back Digging
Designed to sit smoothly against your body without cutting into your skin.
✔ Stay-In-Place Fit
You won’t be adjusting this every set. It just stays where it belongs.
✔ Sculpting, Not Squeezing
Enhances your shape without that uncomfortable, restricted feeling.
✔ Made For Movement
Squats, runs, lifts — it moves with you, not against you.
Use our size chart to find your perfect fit.
