Two massively jacked versions of the duo stand side by side, arms crossed, faces unimpressed — "SCIENCE BUILT THIS BODY" stamped below in stone-carved letters. No back, no explanation needed. For the ones who skip leg day but read every paper. Your people will pause, then nod slowly.

Print Guide

ZENKAI DIRECT INK

Every piece is printed to order using Direct-to-Garment (DTG) technology — the ink goes straight into the cotton fibers instead of sitting on top as a thick layer.

Full detailsharp lines, smooth gradients and rich color, so every artwork looks the way the artist drew it

Soft hand feelthe print breathes and moves with the fabric, no stiff plastic patch

Made for youprinted after you order, which means less overstock and less waste

Each print is applied individually, so slight variations in tone between pieces are part of the process — not a defect.

Care

Fabric: 240 GSM heavyweight 100% cotton, washed finish

Pre-shrunk — keeps its size and shape wash after wash.

To keep your print and fit looking fresh:

Turn inside out before washing
Machine wash cold (30°C / 86°F), gentle cycle, with similar colors
Use mild detergent — no bleach
Hang dry or tumble dry low
Iron inside out on low heat — never iron directly on the print
Do not dry clean

Washed-finish garments may release a little color in the first washes — wash separately the first time.
