Gramicci's backpack, daypack, and backpack made of CORDURA material. The depth is approximately 14-15 cm. According to other sites, the main room is 25L. I think the understated name is a good point. CORDURA material is known as a high-performance material manufactured and sold by Invista in the United States, and its most prominent feature is its high strength. Please be sure to check my profile. This is a home-stored item and is being sold by an amateur, so it is not perfect. Please refrain from purchasing if you are concerned. I may have overlooked some fraying or stains, but please understand this before purchasing. #Men's Fashion #Backpack #Daypack #Day bag #Backpack #Outdoor #Camping #Mountaineering #Sports #Town bag #Unisex ## Color...Khaki
