This backpack utilizes X-PAC, a high-performance material developed by DIMENSION-POLYANT and used in sailcloth (sails for yachts), offering a combination of strength, lightness, and water resistance. The bottom is made of tarpaulin material and equipped with feet to reduce contact with the ground, providing excellent stain and water resistance. A high-performance rain cover with a water pressure resistance of 1,500mm is also included to protect your equipment from sudden rain and dirt. Rain cover and other accessories are included. This is a very sturdy camera bag. It's a rugged, semi-hard case-like bag. It has a metal frame and is very durable.
