Timbuk2 sunset backpack. Used a handful of times but still in great condition. Great for everyday uses as a school backpack or diaper backpack. Inside the main compartment is a padded sleeve that could fit your 15” laptop. Top of the compartment had Velcro to keep it in place. See picture for visual. The backpack has an attached key strap. The two side pockets have magnetic closures. Side pockets are great for holding water bottles.
