Simple and brilliant: PackIt lunch boxes and bags are made of that freezer-gel material, so you can pop the whole bag in the freezer at night, pack lunch in the morning, and it will stay cold for up to 10 hours. No need to find room for those horribly bulky cold packs! The line, which includes lunch sacks, baby bottle bags, wine bags, shopping totes and others, now includes a salad bag – the perfect size for salad containers and bento boxes. $14.99, packit.com
