GOTS

GOTS

GOTS

GOTS (Global Organic Textile Standard) certification guarantees that organic textiles meet strict environmental and social criteria. It covers the entire production chain, from fiber harvesting to the manufacture of the finished product.

In short: organic cotton + manufacturing processes that are closely monitored from start to finish.

Organic cotton

Organic cotton

Organic cotton

Organic cotton is grown without pesticides or synthetic chemical fertilizers. It is gentler on the soil, promotes biodiversity, and protects farmers’ health, while also providing a soft, comfortable fabric for everyday wear.

In short: naturally soft cotton, ideal for garments worn next to the skin.

Composition and care

100% organic cotton

GOTS labelled (Global Organic Textil Standard), our organic cotton t-shirts are certified for their quality and environmentally-friendly manufacturing process.

How to clean your men's t-shirts?

Machine wash at 30°C.

Your men's t-shirts can be machine washed, provided you select a delicate cycle at 30°C with a gentle spin. Use a detergent suitable for everyday fabrics. To protect the colors and any printed designs, turn your t-shirts inside out before washing. Avoid harsh fabric softeners or stain removers, which could affect the colorfastness and weaken the fibers.

Dry flat, in the open air.

After washing, never put your t-shirts in a tumble dryer: the heat could shrink the fabric and distort the neckline. Gently stretch them by hand to restore their original shape, then dry them flat in the open air, away from direct sunlight to preserve the vibrancy of the colors over time.

Do not dry clean.

Dry cleaning is not recommended for your cotton t-shirts. The solvents used are unsuitable for natural fibers and can alter colors, weaken the fabric, and change its texture. For localized stains, hand-treat with cold water and mild soap, then lay flat to air dry.
