Fabric & fit
190 GSM · 100% cotton · DTG print. Oversized drop-shoulder cut. Relaxed through the body and shoulder, so it drapes instead of clinging.
- Oversized by design. Between two sizes, choose the larger one.
- Sizes S to 2XL. Garment measurements in the Size guide.
- 2XL is the largest size. The Fit Finder tells you when it wouldn’t give the oversized fit.
- Direct-to-garment print: the ink sits in the fiber, not on top of it.
Care: machine wash cold, inside out, with like colors. Tumble dry low. Do not iron the print.

The concept. Disuse Atrophy.
The body doesn't maintain what it doesn't use. Motor unit activation and protein synthesis start declining within days of insufficient load. Run it in reverse and you get hypertrophy. No neutral state. The graphic: a muscle belly split in cross-section, dense tissue above, atrophied below. USE IT. LOSE IT.
Front print. Small EMPIRIC mark on the back.
Same principle, other builds

I've had several patients ask where I got it from.
Work with older adults and train them at home. No shirt gets me more locked in before a session. Simple message but it hits. Good quality too.
Every athlete I work with reads this and immediately gets it. Shirt holds up really well too.
