What is the Sympatex membrane?

Technical clothing is essential for facing extreme conditions, whether hiking, skiing or mountaineering. In this world, Sympatex® technology has established itself as an essential reference. Thanks to its membrane that is both waterproof and breathable, it offers optimal protection against humidity while effectively wicking away perspiration. In addition, Sympatex stands out for its environmental commitment, with eco-responsible and recyclable manufacturing. Choosing Sympatex means combining performance and respect for nature, an essential asset for adventurers concerned about their comfort and the ecological impact of their equipment.

How does Sympatex technology work?

The Sympatex® membrane is based on a unique technology that makes it waterproof, breathable and environmentally friendly. Unlike microporous membranes like Gore-Tex, Sympatex uses a non-porous hydrophilic structure. This mechanism works by attracting and expelling moisture through molecular chains, without letting water in from the outside. As the temperature and humidity inside the workwear increases, the membrane becomes more breathable, thus dynamically adapting to the conditions.

In comparison, microporous membranes like Gore-Tex can lose their effectiveness when the pores become clogged with dirt, requiring regular maintenance. Sympatex, thanks to its non-porous technology, maintains its constant performance throughout its lifespan. In addition, being fully recyclable and manufactured without PFC, it offers a significant ecological advantage compared to Gore-Tex, which uses PTFE, which is less environmentally friendly.

The advantages of the Sympatex membrane

The Sympatex® membrane has key advantages that make it a preferred choice for technical clothing designed to face extreme conditions. This is why this technology stands out for its waterproofness, its dynamic breathability and its exceptional durability.

• With water resistance reaching 45,000 mm water column, the Sympatex membrane guarantees total protection against rain and humidity, even in the most extreme weather. Ideal for outerwear such as hiking jackets and ski equipment.
• Unlike other technologies, the Sympatex membrane adapts its breathability according to your activity. The more you move, the more effectively the membrane wicks away perspiration, ensuring optimal comfort whatever the conditions.
• With a stretch capacity of up to 300%, the Sympatex membrane allows exceptional freedom of movement, while remaining resistant to the most demanding environments. Whether you are in the high mountains or hiking, your clothes will remain efficient and comfortable.

In addition, Sympatex stands out for its ecological commitment. Fully recyclable and free of PFCs, this membrane offers a sustainable solution for environmentally conscious adventurers. Adopt Sympatex clothing to combine performance and ecological responsibility.

Sympatex or the eco-responsible choice

The Sympatex® technology has established itself as an essential choice for environmentally conscious consumers. Unlike other membranes, it is free of PFC (perfluorinated compounds) and PTFE, substances often used in the textile industry but criticized for their environmental impact and their difficulty in being recycled. This allows Sympatex to significantly reduce the ecological footprint of its products.

Sympatex also benefits from Bluesign and Oeko-Tex certifications, reference labels which guarantee manufacturing processes that respect human health and the environment. These certifications ensure that each stage of production is carried out under sustainable conditions, without the use of harmful chemical substances. In addition, the Sympatex membrane is fully recyclable, ensuring complete recyclability and responsible waste management.

Sympatex's commitment does not stop there: the brand aims to achieve circular production by 2030, by fully reusing materials to minimize waste and preserve natural resources. By adopting ecological Sympatex, you are choosing a solution that combines performance, durability and respect for the environment.

Comparison of Sympatex with Gore-Tex and other membranes

The Sympatex® membrane stands out from its competitors, notably Gore-Tex, on several essential aspects such as breathability, strong>flexibilityand durability.

• Unlike Gore-Tex, which uses microscopic pores to let water vapor pass through, the Sympatex membrane is hydrophilic and non-porous. It dynamically adapts to the internal humidity level, which allows it to wick away perspiration effectively without the risk of blocked pores. In comparison, Gore-Tex may experience a decline in performance over time, especially if its pores become clogged with impurities.
• Sympatex is capable of stretching up to 300%, providing optimal flexibility for outdoor clothing requiring freedom of movement. On the other hand, Gore-Tex is stiffer, which can limit comfort during activities like hiking or climbing.
• Sympatex retains its waterproof and breathable properties without requiring any special maintenance. In contrast, Gore-Tex requires regular maintenance to restore its waterproofing, which can affect its long-term durability. In addition, Sympatex is 100% recyclable, unlike Gore-Tex which uses PTFE, which is less ecological.

Although Gore-Tex is widely recognized for its waterproof properties, Sympatex offers a more environmentally friendly, flexible and easy-care solution. For those looking for a compromise between performance and environmental impact, Sympatex is often the best choice.

For construction professionals who are often exposed to rain or wet conditions, being properly equipped is essential to staying dry and warm throughout the day. Discover Wintherm® technology, specially designed to offer optimal protection against cold and humidity.

Use of Sympatex membrane and work clothing

The Sympatex® membrane is used in many sectors requiring high-performance technical clothing and equipment, such as hiking clothing, mountaineering clothing, and waterproof footwear. Thanks to its waterproof and breathable properties, Sympatex provides optimal protection against bad weather, ideal for outdoor activities where weather conditions may vary.

Sympatex clothing is designed with different laminated layers, adapted to the specific needs of each activity. The main layers are:

• 2L (2 layers): Perfect for light jackets and clothing rain cover, this layer provides waterproof protection while remaining light and comfortable.
• 3L (3 layers): Designed for more intensive activities such as mountaineering or long hikes, this layer offers better protection and durability.
• 4L (4 layers): Ideal for extreme environments, this layer provides maximum insulation while maintaining excellent breathability.

Sympatex is also commonly used in waterproof footwear, providing reliable protection against water while wicking away perspiration to maintain optimal comfort. Whether for jackets, work pants, or safety shoes, many outdoor brands integrate Sympatex into their products to guarantee performance and respect for the environment.

With its waterproof and breathable properties, the Sympatex membrane is a leading choice for those looking to combine performance and durability. Whether for shoes or clothing, Sympatex offers protection against bad weather without compromising on ecology. Ready to discover the advantages of this technology in your next outdoor equipment?
