Expert Reviews

What experts liked

Rubbermaid also makes several other LunchBlox configurations that will fit inside the bag, like a Sandwich Kit with different-size, separate containers, and a larger Entrée Kit. The Lunch Bag is big enough to hold one of these sets plus a few extra containers or additional ice packs (you can mix and match components from different LunchBlox kits).
We love that there’s a place to store utensils securely and enough space to hold a lunch and a water bottle.
The lightweight design makes this an easy lunch box for your child to carry around. Additionally, two separate cases mean you can send different types of food items without worrying about them mixing.
It has a zippered front panel that opens completely, so you can see all the contents at a glance and have easy access to any item, and it is available in two sizes.
Its lightweight and has a removable shoulder strap.
Multiple size and color options available.
The bag is toxic free. It’s free of PVC, BPA and it just reliable for stacking fruit also.
The lightweight Rubbermaid Lunch Bag with zip closure incorporates a cushioned grip handle making carrying a breeze for on-the-go parents or rush-hour bus chasers. The rounded, padded handle grip will not dig into your palm en route when ferrying a more massive load.
The grip and shoulder strap are powerful and comfortable. There’s a mesh pocket on each end to hold a water jar or thermos and the insulation while perhaps not overwhelming is enough to keep things warm until lunchtime, as long as that you never exit it out.

What experts didn't like

If you flip it over, though, liquids will still leak through the zipper.
Lightweight nature makes it fragile.
Stitching can loosen over time.
Wears and tears over time.
There have been issues with the padded handled breaking. It also doesn’t have as many color or pattern options as some others.
The temparature control and insulation could have been more efficient.
The straps on the inside are slack
May not fit other container brands other than Rubbermaid to optimize space usage

Lunch boxes have come a long way since the metal ones kids took to school decades ago. Today’s lunch boxes are well insulated to allow you to keep food temperatures hot or cold for hours at a time. But these soft-sided lunch boxes also come with some challenges, so it’s important to know what to look for before you shop.

Insulation is the key to temperature control. Although the right insulation can help maintain the cool temperatures your items need in the lunch box after you bring them over from the refrigerator, an ice pack can help. Some lunch boxes also offer separate compartments for cold and hot items to allow you to carry both at the same time.

Storage containers are a great way to pack your favorite items, but it can be tough to find the right size to fit into your lunch box. Some boxes come with containers, making this far easier. If you opt for this, make sure the containers are safe to use in the microwave and wash in the dishwasher. Some lunch boxes come with bento box-style containers, and those are great for keeping portion sizes at a minimum, so look for those if that’s your preference.

For our parenting expert, Kate Desmond, finding an insulated lunch box that’s big enough to fit bento boxes for her kids is a major bonus. This helps eliminate the need for plastic bags, which is another plus.

In addition to compartments for your containers and food items, exterior pockets can come in handy. You’ll have a place to store items like cutlery and condiments or, if you prefer, handy storage for your keys and cellphone. With some lunch boxes, you’ll also get extra pockets on the outside for one or more bottles of water.

“Something to keep in mind if purchasing an insulated lunch box for your kids is ease of opening and closing,” Desmond says. “You want to make sure the box you choose is workable for little fingers. It’s already hard enough for them to put their straw in their juice box and open their yogurt tube, don’t make your kid’s teacher or lunch lady do more work by also having to help them open and close their lunch box.”

When you get home each day, you’ll need to set a little extra time aside to get your lunch box ready for the next use. That means removing all items, wiping the inside clean, and setting it out to dry. You’ll have to wash your containers and make sure they’re ready to go by the next day, if you pack a lunch every workday. Also don’t forget to put your ice packs in the freezer so they’ll be ready for use, even if you aren’t sure how long it will be until the next time you need them.
