Zenoni&Colombi has chosen to produce exclusively in Italy, selecting only local suppliers to guarantee top-quality products. From the design to the finished product, every stage of production is carefully studied within the company to ensure that every detail is executed with the utmost care.

Tailored care and raw materials – Natural fibers, precious raw materials, and precise finishes give the final product unique characteristics and details, often customizable according to the customer's tastes and lifestyle.

Production chain – Compared to traditional distribution, our production chain is shorter. We personally select the raw materials, study and carry out every stage of the product within the company, and then deliver it directly to your home. This way, we can create products within our eco-sustainable production workshop, avoiding large industrial supply chains, while maintaining competitive prices by eliminating intermediaries such as distributors and stores.

Zenoni&Colombi down comforters contain certified Downpass feathers, which allow tracking of every batch of material.

The quality of the down determines the quality of sleep. For this reason, we have decided to make our down comforters starting from a minimum of 90% goose down and 10% small feathers, up to a filling of 100% pure down clusters. Why this choice? Down differs from feathers in its composition: unlike feathers, down has the shape of a cluster and does not have shafts or vanes. This makes down soft, light, and comfortable. Small feathers, on the other hand, mainly used as pillow filling, are small feathers composed of a stem called the quill from which the "barbs" branch out. Down weighs only 2 to 3 milligrams, is breathable, insulating, and temperature-regulating; it therefore maintains a constant temperature.

Once the best raw material is selected, the down undergoes several processes:
- separation: thanks to an air circulation mechanism, feathers and down are separated based on their weight.
- dust removal: a process that eliminates all traces of dust from the down.
- washing and sterilization: feathers and down are washed and sterilized according to the regulations in force in Italy. After an initial sterilization at the end of washing, feathers and down undergo a second sterilization to eliminate all bacteria.
- drying: feathers and down are dried at high temperatures to remove any trace of moisture. Their temperature is then lowered so they can be used.

After these steps, the feather is tested in the laboratory to verify its quality and to assess its filling power.

The filling power, measured in cuin, defines the ratio between the weight and the volume of the filling and is a parameter that must be considered when choosing a duvet. High volume and low weight ensure a high-quality product, made with rich and voluminous down. The duvets commonly found on the market have an average filling power ranging from 400 to 850 cuin; Zenoni&Colombi down starts from a base of 550 cuin up to a maximum of 850 cuin.

After testing, the feather is placed in the bag, positioned, and quilting is performed.

The covers of our duvets are all made from 100% cotton, a natural and breathable fiber. Depending on the line, we have more or less special covers: for our “Polar” line, for example, we chose a 250-thread cotton cover, while for the “Gran Paradiso” line, we have a 450-thread cover (+ threads = higher material quality).

For our down jackets, we use two types of quilting: fixed squares and large box quilting.

Thanks to the Nomite certification, we guarantee that all our duvets are suitable for use by people who suffer from dust allergies. The Oeko-tex certification ensures that all product components are made without the use of substances harmful to health.
