Functional materials are a central element of LangerChen's designs. The brand stands for sophisticated outerwear where aesthetics, responsibility, and technical performance intertwine. The PU membrane plays a key role here. It combines reliable protection against wind and weather with high breathability and a comfortable feel – properties that are essential for LangerChen.
Especially with modern, urban functional clothing, it is crucial to integrate technology unobtrusively into everyday life. LangerChen therefore relies on material solutions that are high-performing without losing their textile character. The PU membrane is a central element for this.

Protection and Function - why the PU membrane is convincing
The PU membrane is a wafer-thin functional layer made of polyurethane, which is incorporated into the fabric construction. It forms an effective barrier against wind and moisture, thus ensuring reliable protection in changing weather conditions. At the same time, the material remains flexible, lightweight, and comfortable to wear.
At LangerChen, the PU membrane is used in a way that preserves the natural feel of the outer fabric. Protection is not created by thick seals, but by precise textile construction. The result is jackets and coats that move quietly, fit well, and are convincing both in everyday life and when traveling. This balance of function and design is an essential part of LangerChen's philosophy.
The main advantages of a PU membrane at a glance:
- reliable protection against wind and moisture
- high breathability through controlled moisture transport
- pleasant, dry body climate
- soft and flexible material properties
- durable with proper care
- versatile for different weather conditions

Breathability and care - crucial for longevity
Breathability is crucial for wearing comfort. The PU membrane works hydrophilically: it absorbs moisture in the form of water vapor and wicks it outwards. This creates a balanced microclimate, even during movement or temperature fluctuations. For LangerChen, breathability does not mean maximum openness, but controlled moisture transport. And precisely where it is needed.
To ensure that protection and breathability are maintained in the long term, proper care is essential. Garments with a PU membrane should be cleaned with mild liquid detergents. Fabric softener should be avoided, as it can impair the function of the membrane. Gentle wash cycles at low temperatures are usually sufficient.
Functional clothing is best air-dried. A short, low-temperature tumble dry can help reactivate the water-repellent properties. With proper care, the PU membrane remains durable and supports the high quality standards that LangerChen stands for.
