Since 2017, we have been producing our materials with high percentages of fine Hemp, patented spinning methods, innovative dyes, and special finishes.

Our fabrics and knitting techniques are the result of 10 years of research, improved and refined year after year—something you won’t find anywhere else. All of this is made possible thanks to our small, artisanal scale and the strong synergy with exclusively Italian suppliers capable of bringing our ideas to life.

from seed to garment
Many brands now say “from the artisan to the product” or “from the field to the product.” Since 2017, we have had control from seed to product—that’s why we’re called “Opera Campi,” because everything comes from the fields. Of course, we’re not yet able to do everything independently, but we know the seed variety, we know where the fields are, and once we have the Hemp yarn, we manage everything autonomously in Italy.
the seeds
The first step is selecting the best seed variety. Not all Hemp seeds are suitable for producing the highest quality yarn. We use two varieties: Futura 75 and Dragon 3.

the fields
Cultivating Hemp with the right humidity in the most fertile soils significantly determines the quality of the final yarn and fabric. Opera Campi has always selected the best fields, the best growers, and the best spinners, defining a “plant index”—a rating for the plant’s quality.
fibre and yarn
From the field comes the retted and scutched fiber, which is then spun. Since 2017, we have been using the finest quality Hemp yarns. Their origin doesn’t matter—we focus solely on the quality required for our fabrics. The Hemp yarn selected by Opera Campi is long-linden, wet-spun, and periodically lab-tested.


italian weaving and knitting
From the yarn onward, Opera Campi rigorously carries out the rest of the process in Italy. Depending on the final product, we work the yarn through weaving, circular knitting machines, or knitting. Even the dyeing is exclusive, using color formulas we have developed ourselves. Few work with Hemp because it’s expensive and requires customizing the machines—something Opera Campi has done for years by working closely with the genius of Italian textile craftsmanship.
technology and finishing
The final touch of Opera Campi is the finishing. By finishing, we mean the set of processes used to dye, soften, and enhance the fabric or the finished garment. Some of these steps include special and natural formulas invented by Opera Campi, such as “Macera”: the water-based solution that softens Hemp.

ALL MATERIALS
Below you’ll find all our materials—past, present, and future—ranging from more to less innovative, whether knitted or woven.
100% Light Hemp Canvas
Real fine natural Hemp yarn is woven into a delicate canvas to become one of our classiest fabric.
Butter Hemp®
Butter Hemp® is our lightest Hemp fabric ever woven. It's a jersey fabric made of the thinnest Hemp fabric. It has been appreciated by textile technicians as the "impossible Hemp fabric".
Active Butter Hemp®
Making a sweatshirt fabric with a high Hemp composition has been a dream for many manufacturers. After years of trials and ideas, Opera Campi added 4% Elasthane to our proprietary 100% Hemp woven fabric to improve elasticity and durability.
Canardina
“Canardina” is a Hemp gabardine, introduced for the first time by Opera Campi. Gabardine is a fabric known for its lightness combined with quality and durability, thanks to the use of very fine yarns that are woven with an almost exaggerated density. The result, when made with Hemp, is a premium summer and mid-season fabric, crafted from very fine yarns (not strictly necessary for this type of fabric) that, when twisted, make the fabric more robust and suitable for trousers, jackets, and other important garments.
Cashemp
Cashemp is a simple, intelligent idea: wrapping thin Italian Hemp filaments around a warm cashmere yarn. The result is a yarn which is strong as Hemp, warm as Cashmere. At first touch you might find it cold: it's the confirmation of the supreme thermal property.
Century-Old Canvas
The centuries-old hemp canvas is recovered from rolls of Italian hemp woven roughly between 1750 and 1900. These rolls are preserved by enthusiasts who have collected them from the grandmothers of friends, or from expert antique dealers. It is a deep search, and each roll is unique. We only select rolls with the weight most suitable for the product to be made. The limited height of the rolls requires careful and manual cutting of the fabric. In terms of quality, being canvases that were made with robust and high-quality threads, it is undoubtedly one of the most durable natural fabrics in the world. The abrasion of the centuries has made these fabrics naturally soft to the touch.
Herotex
The natural fabric with premium performance for all year round, made with a patented technology to make Hemp elastic without reducing the natural composition.
Herotex Canvas
The patented fabric and the world's first elastic hemp. Developed by Opera Campi in 2019, Herotex Canvas is the rawest version of Herotex, featuring a traditional weave but innovative due to its light elasticity, which makes the fabric more comfortable and eliminates the typical wrinkles of hemp.
Iperfine 100% Hemp
Iper-lightweight hemp yarn (36nm), knitted using ultra-lightweight techniques thanks to the use of special fully mechanical Japanese machines that are unavailable on the market. These machines, modified by Opera Campi, allow results that modern digital machines—accustomed to more manageable threads—are unable to achieve.
Knitted Lanapa®
Lanapa is our warmest invention. It's made out of 70% Fine Merino Wool and 30% our premium Hemp. This unique combination makes the fabric warm and sustainable throughout the cold seasons.
Primitive Denim
The tradition of our Hemp weaving has created the finest 100% Hemp denim possible. Thanks to its twisted composition, it is even more durable, with an intense dark blue color that can appear highly elegant.
Superfine 100% Hemp
Ultra-lightweight hemp yarn (24nm), knitted using ultra-lightweight techniques thanks to the use of special fully mechanical Japanese machines that are unavailable on the market. These machines, modified by Opera Campi, allow results that modern digital machines—accustomed to more manageable threads—are unable to achieve.
Velina
The finest woven Hemp fabric in the world. Created exclusively for our shirting line, it’s the most elegant yet lightweight material ever made. Thanks to a special aloe treatment, it achieves an unparalleled softness. The moment you touch it, it feels like a baby’s skin—yet it’s not delicate: Hemp makes it an extraordinarily durable fabric.
Woven 100% Hemp
In 2017 we started with one goal: to imitate ancient Hemp bed linens. We achieved our goal making them softer. Our 100% Woven Hemp fabrics are beautiful, soft, great for any season, and they have are strong, yet elegant.
Woven European Hemp
In 2017 we started with one goal: to imitate ancient Hemp bed linens. We achieved our goal making them softer. Our 100% Woven Hemp fabrics are beautiful, soft, great for any season, and they have are strong, yet elegant.
Woven Lanapa®
Lanapa is our warmest invention. It's made out of 50% Fine Merino Wool and 50% our premium Hemp. This unique combination makes the fabric warm and sustainable throughout the cold seasons.
