Exped's fully waterproof backpack, the Cloudburst 15L in lime green. It has a thin pad on the back. I bought it new and used it once for travel. There are some stains on the lower back and front. Please check the photos. There is no particular damage. The inside is not sticky, and the waterproof performance is perfect. It is a roll-top closure waterproof lightweight dry bag. It may be sold on other sites, and I may cancel the listing. I try to ship as soon as possible after payment is completed. Thank you.
