PackIt if you want integrated gel; Arctic Zone if you want a swap-able ice pack

For an integrated gel pack, the PackIt Freezable Lunch Bag is the best. For a separate ice pack slot, go with an Arctic Zone bag with the Deep Freeze pack.

PackIt’s whole lining is the gel pack. You freeze the entire lunch bag overnight, and every side of it stays cold. No separate ice pack to forget, lose, or cram into a pocket. It works great for kids’ lunches and anyone who packs every day. The downside: it takes up real estate in your freezer, and the bag is heavier and stiffer when frozen.

Arctic Zone’s Deep Freeze lineup is the better option if you want a more traditional lunch bag. The ice pack slides into an insulated slot in the bag (usually in the lid), and you freeze it separately. That means the bag stays flexible and easier to store, and you can buy backup packs to swap in when one thaws. It’s also a good choice if you sometimes want to carry something that doesn’t need to stay cold and want the extra space.

Either way, skip the cheap “insulated” bags that promise cold food without actually having a cold pack. They’re just foil bags.

If you’re not willing to freeze something the night before, no lunch box is going to save you.
