Best Insulated Lunch Box

No sponsored content. No fake reviews. No paid-for posts

Bringing food to work, school, or on a road trip? You need an insulated lunch box. Sure, we get a kick out of old school lunchboxes, especially when they’re adorned with our favorite childhood cartoon characters. And we love the fact that real old ones that are made of tin are now vintage pieces, making for some pretty solid shelf decorations, and that the plastic lunch boxes of the ‘90s also have become collector’s pieces. At the same time, though, we wouldn’t exactly trust them with our food anymore.

If you are looking for a lunchbox that’ll keep your food fresh and delicious, an insulated lunchbox is the way to go. (If you’re not trying to keep your food fresh, well, that’s another story.) They’re a long way from those old school lunch boxes, both on the inside and out. Insulated lunch boxes have an inner layer that is water resistant and generally made out of materials such as plastic, aluminum, vinyl or foil, which are all very safe and common. The outer layers are often somewhat (or very) soft and collapsible, so you can keep the insulated lunch boxes in refrigerators, backpacks, and basically anywhere else. (Whether you want to let your sandwich get squished is your call, of course.)

So, now that we’ve convinced you to buy an insulated lunch box, how can you find one that works best for you? Easy — we’ll help you keep your food cool by recommending the hottest insulated lunch boxes, based directly on reviews by our users. And all of our users have really used the lunch boxes that they’ve reviewed — we don’t allow any sponsored posts or paid reviews. That way you know that you’re getting a great insulated lunch box and feel confident that you’ll be able to enjoy a fresh meal anywhere.

    I have a bento box that I use everyday. First level I put rice and fried egg. Second level I put more protein items like fried chicken or teriyaki salmon. And third levels a salad or cut up fruits. Don’t forget to buy a reusable fork and spoons or chopsticks to go with it. Affordable and help reduce your daily footprint to our planet.

  • Bento Box Lunch Set with Insulated Bag

    $20.99

    By Kinsho

    If you’ve never had the lunch special at a sushi restaurant, you may not be familiar with bento boxes. Basically, they’re deep boxes that are carved into different sections, so that an entire multicourse meal can be served in a single delivery. Kinsho’s bento box lunch set takes the spirit of the Japanese bento box, pairs it with solid plastic and five leakproof compartments, and then places it inside a soft-yet-dependable insulated lunch bag. MASSE shoppers say it works well and fits easily into its bag.

    I recently purchased this and it works well!! The pouchy thing has gel ice packs in it that you can keep in the fridge or freezer to keep cold. And it can easily slide into a backpack!
