The best for elementary school

The PackIt Freezable Lunch Bag has over 40 fun colors and designs, and the entire bag itself is a built-in ice pack, keeping food fresh and cold for hours.

When you have young kids, you'll pay big bucks for anything that makes your life easier and more convenient. Thankfully with the PackIt Freezable Lunch Bag with built-in ice packs, you don't have to shell out too much cash to add a little convenience to your life. Just fold the bag flat in the freezer overnight, and you have a cold lunch bag ready to go for lunches in the morning.

I've had a slightly older version of this lunch box for years, and it keep snacks cool on road trips as well. The bag zips closed at the top to keep food cold, and it has a convenient carrying handle that can also clip onto your child's backpack.

Elementary school kids will love that there are over 40 different designs and colors they can choose from. From tie-dye to unicorns to plain black, there is a PackIt bag to match every style.

A few reviewers note that their bags get wet with condensation as the day goes on, so it would be a good idea to buy one or two of PackIt's mod lunch and snack containers with adjustable compartments to keep food contained and dry. I've never had this problem with my bag, but it is a possibility.

This lunch bag is loved by many with over 2,500 5-star Amazon reviews. It was also praised by Working Mother and Good Housekeeping. Good Housekeeping named it the best overall lunch box. In their tests, it was the only lunch box that safely stayed below 40 degrees after five and a half hours. Working Mother called it "the perfect lunch box for kids who hate carrying lunch boxes."

Pros: Built-in ice packs, over 40 colors and designs, folds flat when not in use

Cons: Some reviewers complain of condensation
