Today's ski jacket jacketsand jackets are made of composite technology materials to achieve waterproof and breathable properties. You may often see descriptions such as 2L and 3L in product names, where L stands for Layer, which refers to the number of layers of fabric composite.
Have you ever wondered why 3L ski jacket sare thinner than 2L? Why is 3L fabric so much more expensive than 2L? What is the difference? Why is 3L the ultimate choice for ski shells? And what is 2.5L?
The 2L ski jacket is affordable and is made of the outermost fabric with a waterproof and breathable membrane. The waterproof membrane is exposed on the inside of the garment, so a layer of cotton or inner lining is usually added to prevent the membrane from being stained or worn and causing the waterproof layer to fail. After this treatment, 2L products are usually a bit thick and heavy, and most of the padded ski jacket jacketsare 2L.
The production process of 3L fabric is more complicated. When compounding, a third layer of lining is added. The waterproof membrane is tightly pressed in the middle, which provides excellent protection and high durability of the fabric. With proper maintenance, 3L equipment can be used for a long time, so some international brands of old clothes only accept 3L products, not 2L.
When using the same waterproof and breathable film, compared with 2L fabric, 3L fabric has better waterproof and breathable performance, and its lifespan is also very durable. Under the protection of the lining, the fabric does not need lining protection, and the weight of the entire product can be controlled to an extremely light level. The manufacturing process of combining the three layers of materials is quite delicate and complicated. In order to ensure the waterproof performance, the splicing parts of the cut pieces need to be additionally processed by lamination. Whether there is glue, and the smoothness and smoothness of the glue strip are also important details to measure the quality of the product.
The half layer of 2.5L is the protective material printed or sprayed on the waterproof and breathable membrane inside the clothes. It can be completely transparent and can resist sweat or oil to a certain extent, increasing the durability of the waterproof membrane. However, even so, this layer of protective material is still easy to wear and tear under conditions such as infiltration, pulling, etc., and the waterproof and breathable performance of 2.5L fabric is still lacking compared to 3L, so 2.5L ski jacket jacketsare better than 3L. It is suitable for some low-intensity, short-term outdoor activities, and the price will be cheaper than 3L.
Generally speaking, ski jackets with different layers are suitable for different outdoor activities and environments. If you often do high-intensity, long-term outdoor sports, then 3L ski jackets are more durable and better protective choices; if you do some low-intensity, short-time activities, then 2.5L or 2L ski jackets Clothes are also a good choice. At the same time, no matter what kind of ski jacket you choose, correct care and maintenance are also the key to ensuring the performance and life of the suit.
