Skull & Sinew Tee

What’s hidden builds what’s seen.

Engineered for those who understand that true strength is forged beneath the surface, the Skull & Sinew Tee blends bold design with powerful symbolism. The front features a striking skull formed from weight plates, gripping a barbell in its jaws — a visual representation of resilience, discipline, and the iron will that shapes every rep.

The phrase “What’s hidden builds what’s seen” is more than a motto — it’s a philosophy. It speaks to the unseen effort, the early mornings, the late nights, and the relentless dedication that builds visible results.

Crafted from premium, breathable fabric for durability and comfort, this tee is designed to move with you — whether you're in the gym, on the street, or pushing through the next challenge.

Train deeper. Live stronger. Let your work speak.
Skull & Sinew – For those who build from within.
