Material: Genuine leather, nylon This is an expandable backpack from Tumi. Purchased at an authorized retailer in 2023. I loved the design so much that I bought it, but I couldn't bring myself to use it for fear of getting it dirty, so it's been on display ever since I bought it. I'm reluctantly selling it because I don't think I'll ever use it. It's highly functional and gives an impression of a clean yet rugged design. I think a backpack with a rugged design that is thin and sleek is rare. It was the last one in the store, and it's a rare model that I couldn't find online or on flea market sites.
