The Science Behind Supima Cotton

Why It's the Secret Ingredient in Your Favorite T-Shirt

Supima cotton isn't just another fabric—it's a rare fiber that makes up less than 1% of the world's cotton. Grown exclusively in the USA, it's engineered by nature to feel softer, last longer, and look better than ordinary cotton.

Extra-Long Staple Fibers

Longer fibers = stronger, smoother, more luxurious fabric.

Supima fibers measure 1.5 inches vs. the 1.1 inches of regular cotton. Those extra millimeters may sound small, but they create yarn that's silkier, more durable, and resistant to fraying.

35% Longer Fibers

Tees that don't thin out or get scratchy.

Superior Strength & Durability

Your favorite tee, built to last.

Supima's long, tightly spun fibers create fabric that's 45% stronger than regular cotton. That means your shirt keeps its shape, resists pilling, and won't sag or wear out after a few washes.

2X More Durable

A tee that feels new, season after season.

Exceptional Softness

The luxury you can feel, wash after wash.

Because Supima has fewer loose fiber ends, the surface feels ultra-smooth against your skin—like a second skin. And unlike other fabrics that lose softness, Supima actually gets softer every time you wash it.

50% Softer

Comfort that only gets better with time.

Superior Color Retention

Your black stays black. Your white stays white.

Supima's unique fiber structure absorbs and locks in dye, keeping colors brilliant long after ordinary cotton fades.

80% Better Color Retention

Vibrant tees that stay photo-ready, wash after wash.
