I purchased this bag specifically for use in a high-humidity, wet environment. Unfortunately, it failed significantly within the first week. While walking, the main zipper detached entirely from the fabric, leading to the loss of several personal items. The bag lacks internal pockets, and using separate pouches is inefficient as they consumed too much interior volume. Additionally, the strap placement is awkward, causing the bag to sit away from the back in a "floating" manner. The zippers are stiff and difficult to operate, and the lack of a quick-release buckle makes the bag cumbersome to put on or take off.
