I bought this stylish backpack for business use, but I only used it to carry my laundered uniform, so it's in good condition. I've used it 10 times and haven't placed it on the ground. It's perfect for mountain climbing, with various features, and I've included many photos with explanations. It's a professional hydration system, compatible with a water bladder and water shade. ・ It has a water inlet on the top of the backpack, allowing you to drink water while walking. ● There are two hooks inside the main compartment to hang a water bladder. ・ Also, there's a compartment to store a 15.6-inch laptop and a 3-liter water bladder. I've included detailed photos. It's used, so it's a used item. I've rated it as having no noticeable stains, but there might be small ones. Thank you for your understanding. No pets, no smokers. Mountain climbing backpack, military bag. Tactical backpack, tactical, camping, hiking, travel, outdoor travel bag. I will fold it in half for shipping. Thank you. #MountainClimbing #MountaineeringBackpack #MountainClimbingBackpack #MilitaryBag #BusinessBag #BusinessBackpack #Backpack
