Dakine Dual laptop backpack fits 15" laptop. Still a current model, sells for about CDN $75
Two years old - great condition, Dakine usually offers limited lifetime warranties on their packs.
I used it for my heavy 15.4" laptop - fit snugly, but safely.
Side access for laptop - extra flap of padding reduces likelihood of water damage. I used it in rain and snow - no moisture got in at laptop.
Great padding all around laptop. Comfortable back padding.
Two large front pockets - one with pencil/cell organizer - and a felt-lined sunglasses pocket at top.
Black and dark grey with red accents.
Some wear around zippers, very little visible wear elsewhere. Fabric is tough and waterproof.
Purchased for CDN $90 - asking KRW 40,000.
