Purchased late January 2022 and only worn twice on winter hikes for about 30 min each time (while wearing a light jacket- so no sweat on pack). No rain or snow during hikes. I only put jackets inside, and put walking sticks and tripod on outside of pack- it is clean inside and out. This is basically new, but since I took the tag off, I cannot return it. Went with a 4400 LT; that's my only reason for selling. $200 shipped.
