10DAYS has always worked to a philosophy of simplicity, authenticity and responsibility. In 2023 it took another important step on its road to a sustainable future, joining the companies certified by GOTS (Global Organic Textile Standard) – the most recognised standard for organic textiles in the world.

GOTS certification confirms that 10DAYS meets strict environmental and social criteria at every stage of production — from growing the raw materials to the finished product. The fabrics used come from organic farming, free of GMOs and pesticides, and the dyeing, weaving and sewing processes respect both the environment and the rights of workers.

For 10DAYS, joining GOTS follows naturally from the philosophy of the brand, built on respect for nature, people and quality. The certificate is not only formal confirmation of environmental practice, it is also a sign of genuine commitment to making clothes that are good for people and for the planet.

Under the GOTS standard the brand commits to full supply chain transparency – every stage of production, from yarn to finished product, is independently audited. 10DAYS keeps working to increase the share of certified materials in its collections while developing circular programmes such as Pre-Loved, Up-cycled and Re-pair, which extend the life of clothes and cut waste.

With GOTS certification, 10DAYS strengthens its commitment to sustainability, offering customers fashion that brings together style, comfort and responsibility. Further proof that real quality does not end with how something looks – it starts with values.

For 10DAYS, choosing natural materials is not only a question of looks or comfort — it is a deliberate decision rooted in the core values of the brand: respect for nature, for quality and for how long a product lasts.

Using organic cotton and other natural fibres significantly reduces the impact production has on the environment. Organic cotton is grown without synthetic pesticides, fertilisers or GMOs, which protects the soil, the water and local ecosystems. That makes the process kinder to farmers and helps preserve biodiversity. Compared with conventional cotton, organic cotton also needs less water, and it is processed without toxic chemicals — in line with the rules of the GOTS certificate that 10DAYS holds.

Natural materials also have a direct effect on how comfortable clothes are to wear. Fabrics such as organic cotton “breathe”, letting the skin regulate its own temperature and moisture. They are soft to the touch, gentle even on sensitive skin, and hard-wearing enough for daily use. It is this natural balance between comfort and function that makes 10DAYS clothes a pleasure to wear season after season.

Choosing natural materials is also an investment in durability and longevity. Clothes made from high-quality organic fibres hold their shape, their colour and their structure for a long time, which reduces the need to buy often and supports the idea of circular fashion. That approach fits the 10DAYS philosophy exactly: less, but better — less excess, more awareness and more genuine quality.

For the customer, this means being able to make more responsible choices without giving up style or comfort. 10DAYS clothes become a symbol of harmony between fashion and nature — a simple but meaningful step towards a more sustainable way of living.

10DAYS is known for its care over quality, durability and a responsible approach to fashion. Its collections are designed for comfort and simplicity, but also with the natural environment in mind. Although organic cotton remains the core material in 10DAYS clothing – particularly in products covered by GOTS certification (Global Organic Textile Standard) – the brand also uses other natural fabrics and blends that deliver the look, the function and the durability it wants.

Wool is one of the oldest and most valued natural fibres in fashion. It regulates temperature exceptionally well – warming on cold days and “breathing” on milder ones. It is also soft, elastic and naturally resistant to creasing.

In its merino wool form, wool is exceptionally fine, which makes it well suited to clothes worn close to the skin – T-shirts, lightweight jumpers and knits. 10DAYS uses wool in some products (including selected T-shirts and jumpers), choosing fibres from responsible sources that follow the “Responsible Animal Fibers” principles. That limits
the impact on the environment and ensures animals are treated ethically.

Linen – natural, breathable and exceptionally hard-wearing. Ideal for warm days, as it cools and lets the skin breathe. It is also biodegradable and fully renewable, entirely in keeping with the principles of the brand.

Lyocell (Tencel™) – a semi-natural fibre made from wood cellulose in an environmentally friendly process. The fabric is smooth, breathable and fully biodegradable, so it works well in the 10DAYS summer drops, where comfort goes hand in hand with function.

Although 10DAYS puts natural materials first, its designs often use fabric blends that combine the advantages of nature with the durability of modern textile technology.

Adding synthetic fibres (elastane, polyamide or acrylic, for example) improves resistance to creasing, stretching and pilling, and makes clothes more comfortable to wear – they follow the body better and hold their shape for far longer.

In the thinking of the brand this is not a compromise but a deliberate choice about quality. The aim at 10DAYS is not to make products that are “purely natural” at any cost, but ones that are durable, functional and able to serve for many years, reducing the need to keep buying more. In this way the brand follows the principles of circular fashion, where durability and responsible consumption are what count.

Every sweatshirt is designed for the modern man who wants more from his clothes than practicality alone. Soft materials that feel good against the skin – most often cotton with a touch of elastane – guarantee excellent breathability and comfort even when worn all day. The fabrics are chosen with care so that they not only look good but also hold their shape and their colour after many washes.

All of these fibres have the potential to keep appearing in 10DAYS collections – particularly as the range grows to include more GOTS-certified products and sustainably sourced materials. Using them is a natural extension of the idea behind the brand: “less is more” – less quantity, more quality, authenticity and respect for nature.

The 10DAYS drive to use natural materials is not a trend but a deliberate strategy that reflects the values of the brand – simplicity, durability, authenticity and responsibility. Using wool, natural fibre blends and potentially linen or lyocell is part of that long-term mission: making clothes that combine style and comfort with care for the environment.

In doing so, 10DAYS steadily builds its position as a brand proving that sustainable fashion can be beautiful, functional and timeless all at once.
