Thank you for viewing! I'm selling this because I no longer use it, although I've used it about 10 times. It has been washed with mont-bell detergent! Product Description The Free Span open-air mesh back panel keeps your back cool, and the breathable material and structure of the shoulder straps provide a comfortable carrying experience. It also has a hip holder, which reduces the swaying of the backpack itself and distributes the weight of the backpack to your hips. The chest strap is also equipped with a whistle as standard, and the adjustment is very easy with the slide type. Hydration compatible (can store a 2.0L Hydro Pack) Zippered access pocket on the top There is also a zippered pocket on the underside of the rain cover There is a zippered pocket on the front where you can put maps and energy bars Equipped with zippered stash pockets (with key hook) and stretch mesh pockets on the sides With stock holder Comes with a dedicated rain cover (unused) Dimensions: 47 x 35.5 x 18cm Weight: 0.87kg * I will also include a Granite Gear Quick Stash, which is convenient for storing your cell phone (compatible with iPhone 6.5 inches) or energy bars. The rain cover that comes with the purchase is unused. I think it's a size that's easy to use for day trips to 1-night, 2-day mountain climbing and hiking, as well as urban use. The condition of the product is good, please check the images. Please note that no claims or returns are accepted after purchasing the product. Instant purchase is OK! Thank you for your consideration.
