Our Natural Tees are available in Premium and Classic styles, both crafted with a retail unisex fit for a modern look thatβs close to the body without being too tight. Made from breathable 100% cotton, they offer comfort and style in every wear. Classic uses high-quality natural cotton, so you may notice small specks in the fabric β a natural characteristic that adds authenticity and charm. All styles may shrink slightly after machine washing and drying.
For a standard fit, men should choose their usual size, or go up a size for a relaxed look. For women, we suggest selecting one size down for a fitted look, or your regular unisex size for a comfortable, slightly looser fit.
For precise measurements, check the size chart above π.
Flip It: Always flip your tee inside out before washing to keep that artwork poppinβ.
Wash Cold, Stay Cool: Toss it in with cold waterβkeeps 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 detergentβno need to go heavy, letβs keep it smooth.
Bleach? Nah. Keep that harsh stuff awayβno fading or ruining your look here.
Air Dry for the Win: Hang it up to dry for max freshness. If youβre 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 upβlet's keep the art clean.
