How does the breathability of PU coated polyester fabric affect its comfort in outdoor gear?

When it comes to outdoor activities, comfort and performance are the goals that every explorer pursues. Choosing the right gear, especially clothing materials, can directly affect your outdoor experience. PU coated polyester fabric is favored for its lightness, durability and water resistance, but how does its breathability affect comfort?

Basic characteristics of PU coated polyester fabric
PU coated polyester fabric is a high-performance fabric that combines polyester fiber with a polyurethane (PU) coating. This material not only has good abrasion resistance and water resistance, but also resists UV damage. Unlike pure polyester, the PU coating provides additional protection, making it excellent in humid environments. However, because of the presence of the coating, breathability becomes a factor that cannot be ignored.

The relationship between breathability and comfort
Breathability refers to the ability of a fabric to allow water vapor to pass through, which is crucial for outdoor activities. During intense exercise, the human body will release heat and moisture through sweat. If the fabric does not have good breathability, sweat will be trapped in the clothing, causing discomfort and loss of body temperature control. Although PU coated polyester fabric performs well in terms of waterproofness, its breathability is often limited. According to a study, many PU coatings have low breathability indicators, which may only be between 500-3000 g/m²/24h, which means that the wearer may feel stuffy during high-intensity activities.

Choosing the right equipment
When choosing outdoor gear, it is important to understand the breathability of PU coated polyester fabric. For long-term hiking or high-intensity mountaineering activities, it is important to choose fabrics with good breathability. Many brands have introduced microporous technology in PU coated materials, which allows the fabric to improve breathability while maintaining waterproofness. For example, some high-end brands of jackets use a design that combines polyurethane coating with a breathable membrane to effectively wick away sweat and keep the wearer dry.

In outdoor activities, the breathability of PU coated polyester fabric directly affects the comfort of wearing. Although this material provides good waterproofness and durability, if it is not breathable enough, it may cause discomfort and overheating. Therefore, when choosing outdoor equipment, be sure to pay attention to the breathability of the fabric to ensure that your equipment can adapt to the changing environment and make your adventure more comfortable. Remember, comfortable equipment is the first step to a successful adventure!
