The main fabric is made of high-strength nylon or polyester and has undergone anti-tear treatment, enabling it to withstand the abrasion caused by shrubs, rocks and other complex environments. 

All-round waterproof protection: The fabric itself has been treated with a long-lasting waterproof coating (PU), and is equipped with a professional rain cover. Even in the event of a sudden heavy rainstorm, it can ensure that the contents inside the bag remain dry and worry-free.
