No one can say that the structure and use of materials are different. According to the definition of "good", it can only be said that the bigger the brand, the higher the price, and the better the design, fabric, durability and experience. You get what you pay. That's basically it. For example, the Lightning Mountain Pant DEMO, I have bought it for three years, more than 700 yuan. Completely waterproof, it rained heavily for two hours and didn't get wet at all. It didn't break after the accident, and it fell lightly without a trace. Although it is thick, it is very breathable. Summer is more than 30 degrees cross-country riding, the upper body is soaked but the thighs are not hot. Two or three hundred Decathlon mountain pants don't have these advantages, and the price is different.

Cycling underwear has pads, which are used for high-speed or long-term or high-intensity fitness, cross-country riding or competition.

There are generally four kinds of cycling shorts, including road bike (tight, high permeability and high perspiration+improving blood circulation+aerodynamic optimization), cross-country mountain bike (loose, high permeability and scratch-resistant composite fabric) and leisure cycling, all of which are equipped with pads and classified into one category. Exchange with the third or second. Brand, consumption power, riding equipment, protective gear, this industry also has BMW Mercedes-Benz similar to cars; Volkswagen; Byd; Different grades of Geely or Wuling. Italian scorpion, American lightning belongs to the former. Look at the domestic GRC in the middle, and then Jieku, Speed Alliance and Sendikou are also good (with a certain reputation in the cycling circle). Decathlon's is ok, cheaper than the above, and the professional design/fabric/appearance is worse than that of the living room, but better.
