Size Guide

Our shirts are cut for real bodies – not highlight reels. We don’t chase aesthetic sizes — we build pressure-first gear that fits fat guys who roll hard.

“Perception says fat. Pressure says heavy.”

Size Chest (in) Chest (cm) Fits Like
XL 44–46 110–117 Heavy roller standard
2XL 47–49 118–124 Built for stack and smother
3XL 50–53 125–135 Big base, bigger pressure
4XL 54–57 136–145 Certified side control suffocation
5XL 58–61 146–155 World-ending weight class

Tip: If you're between sizes — size up for the pub, size down for the squeeze.

Stay Heavy. Roll Hard. Represent Right.
