When choosing a jacket suitable for outdoor activities, the choice of its internal material is particularly critical because it directly affects the comfort and protection of wearing. The following are several recommended high-performance materials:

EPTEE film
EPTEE film is a microporous membrane made of polytetrafluoroethylene through a special process. This material has up to 9 billion micropores per square inch, which form a complex breathable network while maintaining excellent waterproof performance. Wearing a jacket made of EPTEE film can ensure that the body stays dry and comfortable in bad weather.
PU material
PU material, that is, polyurethane fabric, is a synthetic material that imitates natural leather. It is not only durable and has a leather-like texture, but also has a relatively low cost. PU material is respected for its light weight, strong toughness, good breathability and waterproofness. It is one of the preferred materials for making jackets and can provide excellent protection and comfort in outdoor activities.
TPU fabric
TPU fabric is a composite material made by compounding thermoplastic polyurethane (TPU) film or particles with other fabrics. This fabric is favored for its excellent elasticity, wear resistance, cold resistance and environmental protection. In cold environments, TPU fabric jackets can effectively maintain body temperature while resisting bad weather. Its elasticity and wear resistance also provide users with greater freedom of movement and comfort.
In addition to the above three materials, nylon and polyester are also common choices for making jackets. Nylon is popular for its lightness, wear resistance, quick drying and high strength; polyester is respected for its waterproof performance and durability. When choosing a jacket, the most suitable material should be determined according to personal needs and the expected activity environment.
In summary, the internal material of the jacket is extremely important to ensure the comfort and safety of outdoor activities. EPTEE film, PU fabric and TPU fabric are all excellent choices. They all have excellent waterproof, breathable and wear resistance, and can meet the needs of various outdoor activities. When purchasing a jacket, considering these high-performance materials can ensure the best protection and comfort experience in outdoor activities.
