BUFF DAY THE 13TH Tee — Camp-Slasher Menace (Halloween Edition)

Horror × Hypertrophy. From the campsite to the squat rack.

BUFF DAY THE 13TH is our TSF take on a horror legend—mask on, traps out, and ready to take revenge on the weights. Gritty, high-contrast artwork that punches under gym lights and looks mean on the street.

Front print: Buff Day the 13th slasher graphic
Back print: Special Halloween edition “Buff Day the 13th” Iron Demon badge

Buff. Scary. Ready to rock the weights—just like us.
