Big Boss Ramen

Our tees come in three styles – Classic, Premium, and Heavyweight – all with a retail unisex fit. Premium and Heavyweight are made from soft ring-spun combed cotton, while Basic is classic cotton. Heavyweight offers a more relaxed, oversized feel, while Basic and Premium have a modern, streamlined fit. All are breathable, 100% cotton and may shrink slightly after washing and drying. For a standard fit, men can choose their usual size or size up for a relaxed look; women can size down for a fitted look or choose their regular unisex size for a looser fit.

Flip It: Always flip your tee inside out before washing to keep that artwork poppin’.

Wash Cold, Stay Cool: Toss it in with cold water—keeps the fit and the vibe just right.

Gentle Vibes Only: Set your washer to gentle mode. Your tee (and the design) will thank you.

Chill on the Detergent: Use a mild detergent—no need to go heavy, let’s keep it smooth.

Bleach? Nah. Keep that harsh stuff away—no fading or ruining your look here.

Air Dry for the Win: Hang it up to dry for max freshness. If you’re in a hurry, low heat in the dryer works too.

No Hot Presses: If you need to iron, avoid the design. Flip the tee inside out or cover it up—let's keep the art clean.
