Sheets Sets By Fabric

American south west
FARMS
At Porto Luenzo, every Lux Sateen sheet begins in the sunlit fields of the American Southwest, where our SUPIMA® cotton is grown exclusively by multi-generational, family-owned farms. Representing the top one percent of the world’s cotton, SUPIMA® offers extraordinary softness, strength, and purity thanks to its extra-long-staple fibers. Each crop is cultivated with responsible land and water practices, and every bale is certified, verified, and fully traceable—directly supporting American farming families who uphold some of the highest agricultural standards. Naturally smoother, stronger, and more vibrant than ordinary cotton, SUPIMA® creates fabric that remains breathable, soft, and beautifully resilient wash after wash. By choosing SUPIMA®, we honor American growers, ethical production, and a heritage of integrity—forming the foundation of the quiet luxury you feel in every Porto Luenzo sheet.

Factory
Our American SUPIMA fibers then journey across the Atlantic to Portugal, where they are transformed in one of Europe’s most esteemed mills. Our manufacturing partner has spent over 75 years mastering the art of fine bedding. Now led by the fourth generation of the founding family, the mill continues to uphold its legacy of quality, precision, and creativity — blending time-honored craftsmanship with modern innovation. Every sheet, every pillowcase, every detail is created in-house — woven, finished, and tailored by skilled artisans whose expertise has been passed down through generations. The result is bedding that carries the soul of two worlds: the purity of American-grown cotton and the refined mastery of Portuguese textile tradition.

Authenticity
Quality
At Porto Luenzo, luxury begins with confidence — confidence in the cotton, the craftsmanship, and the authenticity of every fiber. Our Luxe SUPIMA® bedding combines genuine SUPIMA® cotton, forensic origin verification, digital traceability, and independent textile testing to ensure purity, performance, and complete transparency.
Authentic & Traceable SUPIMA® Cotton
SUPIMA® partnered with the world leaders in Forensic Testing and Digital Tracking to provide a “shield of assurance” to every SUPIMA fiber. This guarantees that the cotton we use is real, unblended, and responsibly sourced.
- Oritain® scientifically verifies the origin of the cotton using its natural isotopic “fingerprint,” ensuring every fiber is true SUPIMA® from American family farms.
- TextileGenesis™ tracks every bale through a secure digital chain of custody, creating a transparent and immutable record from farm to yarn to finished sheet.
This dual system is recognized globally as the gold standard for cotton authenticity.
Made to OEKO-TEX® Standard 100
All Porto Luenzo bedding is certified to OEKO-TEX® Standard 100, one of the world’s most trusted independent labels for textile safety.This certification ensures that every component — from the cotton fibers to the dyes and finishes — has been tested for harmful substances and is safe for direct skin contact, including for babies and sensitive sleepers.
