This is a large backpack (rucksack) designed with a simple, efficient form, ideal for multi-day trekking with tent camping. Through improvements to the back panel, harness, and frame structure, the load balance has been enhanced to allow for more comfortable carrying of heavy loads while maintaining flexibility. The Liberator Harness, which increases the backpack's rigidity and its ability to conform to the body, has been adopted. This durable, long-life model also features user-friendly elements unique to large packs, such as a bottom zipper for easy access to the main compartment and a divider for separating the contents. ★ Brand new, unused. ★ Reference price: ¥59,400 (tax included) ★ Materials: Main body: ECO AZTEC Canvas, 840D Cordura Nylon * Due to the nature of the materials, please be aware that color may fade or transfer when wet or due to friction. ★ Size: S3 80L Back length: Approximately 42-49cm Please allow for some margin of error. ★ Color: Black Colors may appear different from the actual product depending on your monitor environment.
