Materials & certifications

Materials

Cotton

A soft, breathable, absorbent, and versatile natural fiber grown from the fluffy bolls of cotton plants.

Good to know: Conventional cotton is one of the world's dirtiest crops as cultivation heavily relies on pesticides, herbicides (glyphosate), and fertilizers, raising concerns about environmental pollution, soil health, and potential health risks for farmers and consumers. This is why some brands and consumers push for "100% organic cotton." Organic cotton skips the harsh chemicals, making it a more eco-friendly and healthier choice.

Hemp

A versatile and durable natural fiber derived from the long, tough stalks of the Cannabis sativa plant known for its durability, sustainability, and moisture-wicking properties.

Uses: Commonly used in clothing (shirts, dresses, jeans, jackets), home textiles (curtains, rugs, towels), bedding (sheets, duvet covers), paper products, construction materials, upholstery, cushions, and even furniture frames.

Good to know: Hemp cultivation requires minimal pesticides and herbicides, and it returns 60-70% of the nutrients it takes from the soil. Hemp fabric also offers UV protection and has antimicrobial properties, making it a healthy choice for skin.

Lyocell

A regenerated cellulose fiber derived from wood pulp, often eucalyptus, beech trees, or bamboo. This material possesses a soft, comfortable feel similar to cotton yet exhibits superior strength and durability, even when wet.

Uses: Commonly used in clothing (shirts, pants, dresses, underwear), bedding (sheets, towels, blankets) home textiles (curtains, tablecloths, etc.), and various industrial applications.

Good to know: Unlike conventional viscose or rayon, the production of lyocell uses a closed-loop system that recycles most of the solvents, minimizing environmental impact and chemical exposure. Furthermore, in comparison to other cellulose-based fabrics, lyocell uses significantly fewer and less harmful chemicals during processing. For example, in most cases, the wood pulp is dissolved in a non-toxic organic solvent, N-methylmorpholine N-oxide (NMMO), to create a solution. This solution is then extruded through fine openings to form filaments, which are solidified into fibers.

Silk

A naturally occurring protein fiber spun by the larvae of certain silkworms, prized for its smooth texture, lustrous sheen, and exceptional strength.

Uses: Traditionally used in luxurious clothing (dresses, gowns, lingerie), but also popular in scarves, home textiles (curtains, bedspreads), and upholstery.

Wool

Wool is a natural protein fiber obtained from the fleece of sheep and other animals, including alpacas, goats (such as cashmere and mohair goats), and rabbits (like angora). It's known for its durability, insulation properties, and ability to absorb moisture without feeling wet.
