WearerCo: Why We Use Supima Cotton
At WearerCo, we believe that exceptional clothing starts with exceptional materials. That’s why we choose Supima Cotton, the world’s finest cotton, to craft our premium apparel. Grown exclusively in the United States, Supima Cotton represents less than 1% of the world’s cotton production, making it a rare and luxurious choice for those who value quality, comfort, and sustainability. Below, we explain what makes Supima Cotton so special and why it’s the perfect fabric for your wardrobe.
What Is Supima Cotton?
Supima Cotton, short for “Superior Pima,” is a premium variety of cotton derived from the Gossypium barbadense plant, known for its extra-long staple (ELS) fibers that measure at least 1.5 inches (3.8 cm) in length—nearly 50% longer than regular cotton fibers. Grown in the arid climates of California, Arizona, New Mexico, and Texas, Supima Cotton is cultivated by approximately 500 farmers under the strict standards of the American Supima Association (ASA), ensuring authenticity and unmatched quality. The name “Supima” reflects its heritage, rooted in the Pima Indian tribe’s legacy of growing high-quality cotton in the American Southwest.

-
Unparalleled Softness
Supima Cotton’s extra-long fibers create an incredibly soft and silky fabric that feels luxurious against the skin. Unlike regular cotton, which has shorter fibers (around 1 inch), Supima’s longer fibers result in smoother, finer yarns that give our garments a cashmere-like texture. Whether you’re wearing a WearerCo T-shirt or loungewear, you’ll experience cloud-like comfort that elevates everyday wear. -
Exceptional Durability
Supima Cotton is up to 45% stronger than regular cotton, thanks to its long, tensile fibers. This strength makes our garments highly resistant to wear, tear, and fraying, ensuring they maintain their shape and quality even after frequent washing and wearing. Unlike standard cotton, which may thin or tear over time, Supima Cotton products are built to last, offering long-term value for your investment. -
Superior Color Retention
The long, fine fibers of Supima Cotton absorb dyes more effectively, resulting in vibrant, long-lasting colors that resist fading. Whether you choose a bold hue or a classic neutral, your WearerCo garments will maintain their brilliance wash after wash, keeping your wardrobe looking fresh and stylish. -
Pilling Resistance
Unlike regular cotton, which can develop tiny balls of tangled fibers (pilling) after about 10 washes, Supima Cotton’s smooth, long fibers create a fabric surface with fewer loose ends. This makes our clothing highly resistant to pilling, ensuring your T-shirts, shirts, and loungewear stay smooth and pristine for years. -
Breathability and Comfort
Supima Cotton is naturally breathable and moisture-wicking, making it ideal for all seasons and climates. Its fine fibers allow for excellent airflow, keeping you cool in warm weather and comfortable in cooler conditions. Whether you’re lounging at home or on the go, WearerCo’s Supima Cotton garments provide all-day comfort without feeling heavy or suffocating. -
Hypoallergenic and Skin-Friendly
Supima Cotton is naturally hypoallergenic, making it an excellent choice for those with sensitive skin or allergies. Its smooth texture minimizes irritation, and its resistance to carrying allergy-causing microbes ensures a gentle, skin-friendly experience. This makes WearerCo apparel perfect for everyone, especially those who prioritize comfort and skin health. -
Sustainability and Ethical Production
Supima Cotton is grown with a commitment to sustainability, using advanced techniques like drip irrigation and GPS-navigated tractors to minimize water usage and environmental impact. The ASA enforces strict guidelines to ensure eco-friendly and non-toxic cultivation practices, making Supima Cotton a responsible choice. Additionally, Supima Cotton is fully compostable, decomposing in soil within 3-6 months, reducing waste. By choosing WearerCo, you’re supporting sustainable fashion that’s better for the planet. -
Versatility for Everyday Luxury
Supima Cotton’s unique combination of softness, strength, and elegance makes it ideal for a wide range of WearerCo products, from T-shirts and dress shirts to loungewear and bedding. Its luxurious feel rivals silk, but with the practicality of cotton, allowing you to enjoy premium quality in both casual and sophisticated styles.
- Cultivation: Grown in the hot, arid climates of the U.S. Southwest, Supima Cotton thrives under controlled irrigation and sustainable farming practices.
- Harvesting: The cotton is carefully harvested, often by hand or with specialized machinery, to preserve the integrity of its long fibers.
- Processing: Fibers are separated from seeds, cleaned, carded, and combed to remove impurities, then spun into fine, strong yarns. These yarns are woven into smooth, durable fabrics for WearerCo’s garments.
-
Certification: The ASA certifies every batch of Supima Cotton, ensuring 100% authenticity and adherence to strict quality standards.
-
Wash: Machine wash in cold or warm water (avoid hot water) with a mild detergent to preserve fiber strength and color vibrancy. Turn garments inside out to minimize friction.
-
Avoid Bleach: Use gentle alternatives like white vinegar or baking soda to avoid weakening the fibers.
-
Dry: Air dry when possible to maintain softness, or use a low-heat tumble dry setting.
-
Enjoy Over Time: Unlike other fabrics that wear out, Supima Cotton often becomes softer with each wash, enhancing its luxurious feel.
