Unique techniques ensure our clothes are treated with natural extracts and the utmost respect for the environment. Their quality shows in their feel and in their natural hues obtained through the use of plant dyes.

Plant Dyeing

Plant dyes have been used for millennia. Made from natural ingredients such as leaves and stems of indigo woad, cedar wood, walnut bark, onion and pomegranate skins, or even Pu’er tea, they preserve ancient craftsmanship and offer a wide range of subtly nuanced colours.

Committed to nature, ICICLE fosters these traditional artisanal techniques to craft its collections. Biodegradable, plant dyes offer natural hypoallergenic properties and respect even the most sensitive skins. They resonate with ICICLE’s determination to produce comfortable, long-lasting garments.

In its quest for innovative and sustainable solutions, ICICLE participates in the “Food Textile“ project, which repurposes irregularly shaped fruits and vegetables, peels, coffee grounds, and other food products scheduled for disposal. Through an exclusive patented technology, these materials are transformed into plant dyes, contributing to the reduction of food waste.

  • Vegetable Tanned Leather

    Our vegetable tanned leather goods are handcrafted in Italy. We use finely selected leather, dyed with natural plant extracts and entirely free from toxic agents.

  • This complex multi-step tanning process, spanning from several days to several months, ensures the leather is light and delicate yet still durable.

  • We utilise natural vegetable tanning agents such as chestnut, pine, or mimosa bark and leaves. They allow a close-to-the-skin carefree experience.

  • Precise cuts at the design stage help minimise waste, reducing both scrap production and energy consumption.

  • We only work with Italian tanneries certified by Leather Working Group, and select calfskin for its incomparable elasticity and overall superior quality.

  • After a natural plant tanning treatment, our leather becomes incredibly soft to the touch, as if it was a second skin. It develops a distinctive patina over time.

Rain-Treated Linen

Flax is left to soak in rainwater to wash out the naturally occurring gum that coats the plant fibre. Rainwater, acting as a natural treatment agent, softens the fibres and makes them more supple. Environmentally friendly, this traditional method reveals the fibres’ natural colour, which may vary in shades depending on the temperatures flax was exposed to during its growth.

Grain Coating

After dyeing the fabric, thanks to natural methods, powder is extracted from various grains used to coat its surface, which is then rinsed and washed. This natural finishing technique forms a protective layer on the fabric, enhancing its durability against wear and moisture.


Using an ancient and complex artisanal dyeing technique, gambiered Canton gauze is crafted with natural elements. The silk is first rubbed and soaked in yam sap, a medicinal plant from southern China. It slowly absorbs this plant dye before being sun-dried for a long time to fix the colour. These meticulous steps are repeated approximately thirty times. Through this process, the silk develops a distinctive ochre hue.

One side of the fabric is then coated with a delicate layer of riverbed mud, that is rich in tannin. As it dries in the sun, the silk reacts with minerals, resulting in a characteristic polished appearance. Mud excess is then washed away. The resulting fabric reveals a darker, smoother front side, while the back remains ochre and matte. Also known as “fragrant cloud silk“ in China, it forms a patina over time, acquiring a truly unique character.
