This is a Porter Hybrid daypack. It was used as a business bag for commuting. I've used it for a year and a half. I used it for my commute by car, so I used it almost every day, but I mostly carried it by hand. It's convenient for storing A4 files and a laptop with ease, but I'm selling it because I no longer need to carry luggage due to a job change. There is some wear and tear in various places, but there are no defects. It still holds its shape. It is also well-waterproofed, and will not be penetrated by water in the short distance (a few dozen meters) to the car. I will clean it up before shipping. There are no purchase proofs such as receipts or Porter cards. The item for sale is only the bag in the photos. Porter Backpack, Rucksack, Waterproof
