Purchased last year and used 5 times for low-mountain hikes in autumn and winter (including one snow hike). Used by a woman. Since a shoulder pouch was used in conjunction, the mesh pockets on the shoulder straps were not used. There is one thin stain on the side of the zipper of the top pocket. It's usually inside the wrinkles, so it's not noticeable, but it can be seen when the fabric is stretched. (Photos 17 and 18) In preparation for listing, the back pad has been removed and hand-washed with a mild detergent. The main body of the backpack has been wiped with food-grade alcohol. Please feel free to ask if you have any questions. Thank you.
