Call it a Rucksack or a Backpack, but these multi-pocketed utilitarian bags are back in style in a big way. They are practical, and available in many colors, fabrics, designs, and prints. They are great for hauling essentials, a compactable jacket, sweater, or cardigan, a bottled drink, snacks, maps, a book, art supplies...etc.
They are fantastic for traveling, festivals, baby gear, students, or just doing errands, as they hold a lot, yet are nice looking bags. I went to Target today, and saw many of them there, though I started putting this collection together months ago.
