We, at Cimalp, have been developing our own in-house technologies and fabrics for more than 50 years. Cimaflex, Cimadry, Cimashell, Ultrashell, Cyclone… Those patented technologies and fabrics all provide ultimate performance, unfailing protection and improved durability, which are our guiding principles from the outset. 

We are working daily on developing a variety of creative fabrics, light & comfortable, waterproof, windproof, breathable, easy to wear & care, all developed in the modern context of eco-design.

Take, for example, our in-house membranes. They have been developed with 2 goals in mind:

  • Reaching ratings on a scale that hardly bears thinking about, in order to surpass the performance level of the benchmark, such as water repellency, moisture management, anti-bacterial/odour control, UV-protection… 
  • Achieving such functional properties with synthetic fibres being climate-neutral, Bluesign® certified, meeting the 'Oeko-Tex-Standard 100' certificate, and above all being PTFE-free and PFC-free.

Our technologies and procedures are based on the principles of ecological responsibility and sustainability.

The company production is at the forefront of innovation, improving anyone’s mountain experience, thanks to premium fibres or patented technologies:


MERINO WOOL - Merino wool has finer fibres than wool. The merino wool fibres are between 14.6-24.5 microns. A micron (μm) is one millionth of a meter; the finer the micron, the softer the fibre. It is renowned for its next to skin softness, which is why it’s very suitable for underwear, t-shirts and long sleeves. Merino wool offers superior stretch properties than coarser types of wool, creating an elasticity that always returns to its original natural shape, making it ideal for movement and mobility. In addition to these benefits, merino wool protects from UVA and UVB rays without any additional fabric treatment.


SILK – The “skin-friendly” fibre, featuring anti-aging properties by moisturizing the skin and accelerating the cell renewal process. It is hypoallergenic, it does not attract dust mites, and it is a natural fungal repellent. By avoiding the accumulation of bacteria, silk has natural anti-odour properties.

BAMBOO - Our fabric is a blend made from bamboo called Rayon. It has the properties of being extremely absorbent with excellent wicking properties, and is also sublimely soft, antibacterial, antimicrobial and hypoallergenic. Bamboo is a fast-growing crop requiring little or no chemicals to thrive, making it a sustainable resource. Mixed with Silk as it is at CIMALP this fabric is soft and comfortable next to skin.


ULTRASHELL - Hardshell jackets or trousers are designed to be the most protective outer layers against wind and heavy precipitation. Hardshells fabrics all share a 3-layer build: a waterproof and breathable membrane is sandwiched between an interior liner and durable exterior face fabric. A few years ago, following the DUPONT DE NEMOURS scandal, we decided to stop using membranes containing PFCs. After two years of research in partnership with English laboratories, we succeeded where even the major brands still don’t. We not only managed to produce a 100% PFC Free membrane, but one that performs even better! At the heart of this technology is a ultra-thin membrane with pores 20,000 times smaller than water droplets, but large enough for perspiration to pass through. Laminated with reinforced face fabrics and thermo-welded seams on the inner fabric, it provides protection for the harshest weather conditions and the most demanding outdoor activities.


CIMASHELL - A softshell, as its name states, is a cozy and stretchable outer layer. Softshell products feature a durable nylon or polyester face fabric, an comfortable interior—often made out of brushed polyester or fleece, and, in-between, a waterproof and breathable membrane, making these jackets or trousers great for mountain environments Yet, while a softshell does a decent job at resisting wind and sluffing off a light rain or snow, it is not built for all-day protection in the wettest of weather.


CIMAFLEX - This 4-way stretch structure offers good thermal insulation, breathability and moisture wicking properties. As such, it is used to design particularly breathable and flexible fleece jackets that allow a great freedom of movement. The fabric is stretchable, resistant, slightly wind protective on the outside, and super soft and fleecy on the inside. The warmth/weight ratio is very good, making these garments ideal for outdoor sports in chilly weather, or as a midlayer in colder conditions. 

CIMADRY – The CYCLONE® TECHNOLOGY is definitely a disruptive one, based on nanotechnologies providing textile fibres with hydrophobic or hydrophilic properties. When mixed together, they then work like a natural water pump. Cyclone® technology "sucks" water from the inside of the fabric and releases it to the outside.  It allows moisture to be transferred up to 10 times faster than with conventional fabrics.  CimAlp won the 1st prize in the French Outdoor Award 2015 in the trail category for this technology.  


POLYGIENE - Polygiene® permanently stops the proliferation of bacteria and fungi that cause bad smells. To achieve this, it uses low concentrations of salt of silver (silver chloride), which has anti-microbe properties and is naturally present in water and soil, to work against the growth of bacteria and fungi. The permanent treatment is applied in the finishing stages of the textile process. Field and lab tests have shown that odours are kept to a minimum for a longer time that the useful life of the item of clothing. This can be achieved thanks to the fact that the technology is permanently integrated in the fabric and does not go away after washing.


“LA POCHETTE INFINIE” – 100% recycled 100% recyclable - We are passionate about offering truly sustainable alternatives. We are proud to be the first e-shop to use high-quality, dependable poly mailer made entirely from waste. By producing shipping packaging from 100% recycled consumer waste we are able to ‘close the loop’, diverting plastics from landfills and extending their use. Of course they are also 100% recyclable.
