Everest Classic Woodland Camo Backpack, One Size

This backpack is a great size for a daypack. I would estimate the size to be about 12" x 15" and about 5" thick. I couldn't find the dimensions anywhere in the listing!! VERY well made; zippers are standard. The material against your back, which can get sweaty, has a plastic lining inside the bag. As other reviewers have noted, not a lot of internal sections, but I find that things tend to get lost in those sections!! I managed to put a 10x12' folded camping ground tarp and a summer-thickness sleeping bag in a compression bag into the backpack! Not much room left after those two items, however. Price was rolled back to about $9, which is amazing!!
