insulated lunch bags Buyer’s Guide

If you keep the before points in mind, you can easily go out to the market and buy insulated lunch bags, right? No!

The Insider Pick

School lunches are very often mediocre, and it costs a lot of money to buy food every day. So why not pack your lunch in an awesome lunch box? We’ve rounded up the very best lunch boxes for pre-school, elementary school, middle school, high school, college, and professional life.

Whether your child is heading back to school, you are going back to school, or you’ve just grown tired of buying your lunch from the food truck outside your workplace each day, there’s no denying that a new lunch box makes the midday meal just a little bit tastier.

We visited the top consumer websites to check out the research, and listened to buyer feedback on what owners love — and don’t love — about their purchases. So if you’re ready to eat, forget about that crumpled paper sack, and read on. Here are the five lunch boxes that we most recommend.

The Bentgo Kids Bento Box, the Packit Freezable Lunch Bag, the L.L. Bean Flip-Top Lunch Box, the L.L. Bean Insulated Lunch Box, and the Ramaka Solutions Insulated Lunch Bag are the best lunch boxes you can buy no matter your age.


The bag is overall recommended because it carries a lot in a compact space. Trainers and athletes can pack several full meals and snacks in this bag. The shaker cup can easily mix meal supplements or protein powder for athletically-inclined users. The shaker bottle also doubles as a water bottle.

No shoulder strap

This bag is large enough to fit not just food, but other accessories as well. A folded towel and sunglasses can be carried with ease, particularly for those who wish to take the bag on a picnic or hiking trip. The bag also has a fleece-lined pocket and two additional insulated pockets. The larger compartment is designed to carry as many as three full meals. Cutlery utensils are not included, but they can be carried in the zipper compartment. The pack does include three plastic containers with lids. These containers are designed to hold meals, and the pack also includes a smaller container for carrying smaller items, such as vitamin supplements.

This pack is recommended for its organizational capabilities. The meal system even includes a small, removable pouch along with the bag. This pouch can hold small personal items, such as a cell phone or wallet.

Must be carried on the back with shoulder straps

This LISH bag is intended for the sporty user who wishes to tote multiple small meals and snacks at once, either to the gym or on a hiking trip. Users who wish to cook and transport healthy meals will find this bag a viable option. The bag has both a top carrying handle and a detachable shoulder strap. The six containers include four larger square containers and two smaller rectangular ones. One ice pack to keep food fresh and cool is also included in the bag. A small, plastic vitamin supplement container is also included. The side mesh pocket makes it easy to carry a water bottle or sports drink.

The included ice pack can keep food fresh for a couple of hours. However, if the user wants the food to stay fresh all day, it is highly recommended that the user purchase a second ice pack to go along with the included one.

The pack is overall recommended for its simplicity. It easily fits the six included containers, and there is a side pocket for additional storage space.

No extra features

In addition to the meal bag, this system also includes four large containers to fit up to four meals. An adjustable bottle holder is made onto the side of the bag, and this is intended for the user to carry a water bottle or another drink. The bag itself is insulated, which helps to keep food cool and fresh. Made for durability, the bag is lined with quality nylon inside and a polyester shell outside. Buyers have a choice between a red, black, grey or blue bag.

Overall, the bag is recommended as a good choice for those who want a simple bag and do not need lots of additional storage space.


Meal prep bags come in all colors. Bright neon ones are best for the gym or best to be used as a travel cooler. A basic black bag is inconspicuous and looks professional. Neon colors are generally not a great fit for a professional office environment.

Straps and Handles

Some meal prep bags include both a carrying handle atop the bag as well as a shoulder strap. When shopping for a meal prep bag, the customer should consider which feature is most important. For ease of use, the shoulder strap is perhaps the most comfortable. A shoulder strap with a metal harness tends to be sturdier than a plastic one. Meal prep bags with only carrying handles on top will work if the bag is a small one (measuring less than 1inches high and 1inches wide). Otherwise, carrying the bag using the top handle will most often cause the bag to rip or come unstitched.


All of the meal prep bags mentioned here are insulated, but in most cases, insulation simply consists of strips of foam underneath a layer of nylon. Even the best of these products can get worn down with time. Thus, the most trustworthy companies will offer a warranty.

Who should get this

If you or your kids have a lunch box that is difficult to clean and is beginning to smell a little funky, it’s probably time for a new one. If you’re an adult who works in remote locations, or if you have kids in grades K–12, access to refrigeration for packed lunches is unlikely. A durable, insulated lunch box is a must for holding ice packs and keeping foods at safe temperatures.

Young kids who go to daycare or preschool could benefit from a bento-style lunch box because such designs are easy for caretakers to label, clean, and stack neatly in a crowded refrigerator. Small food storage containers are another great option for parents to easily portion and separate foods for placement inside an insulated lunch box.

How we picked and tested

After researching 50 lunch containers, we tested 1for this guide.

For this guide we tested lunch boxes for both adults and kids, covering insulated lunch boxes, bento boxes, and metal and plastic food storage containers. Regardless of the type of lunch container you use, it should be break-resistant, stain-resistant, and easy to clean and store. Food storage containers should also be leakproof.

Since insulated lunch boxes are intended to keep food cold without refrigeration, they need to be large enough to hold a substantial lunch and multiple ice packs (ideally, they should have a mesh pocket on the interior lid for holding an ice pack in place). A shoulder strap is a must if you’re an outdoor worker, especially if you’re carrying other equipment to a jobsite. Though we had difficulty finding waterproof lunch boxes, an exterior material that’s slow to absorb liquids is a nice feature for keeping rainwater out, especially when you’re working outdoors.

For kids, we looked for insulated lunch boxes that were roomy enough to hold an average-size lunch yet compact enough to fit in a backpack. We tested lunch boxes with mesh pockets on the side, which are convenient for holding additional snacks.

Some parents feel uncomfortable using plastic food storage containers. For this reason, we decided to try a couple of metal containers, which are a good alternative to glass because they weigh less and won’t break. However, they can’t go into a microwave to reheat your lunch, and they aren’t leakproof. (We do recommend several glass options in our guide to the best food storage containers).

Our picks for the best insulated lunch boxes: the L.L.Bean Lunch Box (left) and the Coleman 9-Can Soft Cooler (right).

We also looked for bento-style boxes for young kids and adults that have either separate compartments with individual lids or a single lid that seals the entire box. Bento designs with a single lid need to be airtight to prevent the contents from spilling over the compartment walls and to keep food odors from mingling. Cassie Hollmann, assistant children’s programming director at Citibabes in New York, who works with kids from months to years old, told us, “A good seal might be the most important thing.” A tight seal is especially important for little kids who store their lunches in their backpacks or cubbies. “Many times backpacks, lunch boxes, and shoes end up upside down and haphazardly put away,” Hollmann said.

Some bento boxes, such as the Bentgo Kids Lunch Box, have a single lid that covers individual compartments.

No adult bento boxes did well in our tests. If you prefer packing your lunch in separate compartments, we’ve found that nothing works better than glass or plastic food storage containers.

Care and maintenance

It’s important to keep the contents of a lunch box within an acceptable temperature range for food safety. In an article for Foodsafety.gov, Bridgette A. Keefe writes, “Remember the 2-Hour rule: you must keep hot foods HOT and cold foods COLD.” Perishables last only two hours in temperatures between 40°F and 90°F before they spoil. If the temperature of food is between 90°F and 140°F, perishables will last only about one hour before you need to refrigerate or freeze them. Always keep cold foods under 40°F and hot foods above 140°F. If you or your child don’t have access to a refrigerator, the USDA recommends using two cold packs (larger than by inches each), one above and one below perishable items such as dairy or sandwiches.

Most insulated lunch boxes are not machine washable or dishwasher safe. Manufacturers suggest wiping insulated lunch boxes clean with a mild dish detergent and a damp paper towel. Be sure to dry an insulated lunch box with paper towels or a cloth and leave it open and unzipped to air dry completely before you use it. Your best bet is to clean an insulated lunch box once or twice a week to prevent it from acquiring an unpleasant, off scent.

For difficult stains, such as those from tomato sauce, removing the soiled area may take multiple attempts. If the exterior becomes stained, we recommend cleaning it immediately with a little soap and water for best results.

Most plastic and metal food storage containers are dishwasher safe (top rack only), but always read the manufacturer’s instructions for proper use and care. For some bento boxes with rubber seals around the lid, wash by hand to avoid possible deterioration.

The competition

The Rubbermaid LunchBlox Sandwich Kit 180623is a great storage option for young kids. These containers stack together nicely and lock into a plastic, freezable ice pack, which in our tests kept foods at safe temperatures for nearly four hours. However, since this set is so tall when stacked, it doesn’t fit into shallower lunch boxes like our pick from L.L.Bean.

For young kids, the ECOlunchbox Three-in-One is a nice, compact stainless steel option. The metal containers are easy to clean and dishwasher safe. This lunch box didn’t suffer any dents or permanent damage in our drop tests, but we ruled it out because it’s not leakproof and it’s too small for older kids and adults.

The Ramaka Solutions Insulated Lunch Bag is cheaply made and too big to serve as a lunch bag for a single person. The thin walls of this bag also lack structure, so it sags when fully packed. In our tests the exterior of the bag stained badly with tomato sauce, and the interior lining was difficult to wipe clean. However, a representative from Ramaka Solutions has informed us that this bag is now being made by a new supplier. We’ll consider testing the new bag for our next update.

Because the Herschel Canteen Lunch Pack lacks a handle, it’s inconvenient to hold. In person, the color of this bag is neon orange, as opposed to the rust color depicted on the Herschel website. We found that the inner lining stained easily, and it was difficult to clean.

The Wildkin Lunch Box has an inner lining with a lot of seams that trap crumbs and make cleaning difficult. In our tests the interior stained badly with tomato sauce.

The Bentgo All-in-one Stackable Bento Lunch Box was a pain to use. We had trouble fitting the lids onto the containers, and the plastic cutlery was a nuisance. The elastic band stained badly with tomato sauce and was difficult to remove.

The Bentology Bento Set seems cheaply made. The lids do not fit the bases well (before or after dishwashing), and they’re not leakproof.

The Happy Tiffin Raja Tier Tiffin Lunch Box is too large for a lunch portion; it’s more suitable for bringing to picnics. It’s also a bit tall to fit in a crowded fridge, especially if you’re bringing it to work. It dented in our drop tests.

Pupsik Studio

WHAT This was created to store both bottles and breastpumps in one cooler bag. Two compartments let you stash all sorts of accessories and pump parts, while a waterproof, dirt-resistant outer layer makes it durable and easy to maintain. The fully insulated inner padding keeps milk cold for up to hours.

Mum’s Fairy

WHAT Spacious and versatile, this carrier is a discreet way to carry all the equipment you need to express your milk. You can carry by hand, use the shoulder sling, as a backpack, or attach it to your stroller. Made from a strong, longlasting material, it boasts a waterproof and insulated lining.

PARENTS SAY You’ll enjoy easy access to the contents, especially when you’re busy with your baby, thanks to the wide opening. It’s also large enough to hold most breast pumps and all its parts. Though the design is very basic, we like the versatility offered by the different ways in which we can carry it.


WHAT Simply collapse the cooler bag, pop it into the freezer for hours and it’s ready to use! Fits six bottles ― the tote handle makes it easy to carry around. The built-in cooling panels will keep your milk chilled for 1hours.

PARENTS SAY You don’t have to deal with ice packs or messy condensation with this spacious cooler bag. Although it’s expensive, you know you’re paying for something reliable. You can easily use it to transport food and drinks for outings and picnics when your pumping days are over.

Agape Babies

WHAT Pumping mums will love this portable BPA-free cooler set that will keep your breastmilk cool and safe. Comes with four Medela storage milk bottles ― very handy! ― and a contoured ice pack.

PARENTS SAY This is probably the cooler bag you’ll want to go for if you are using a Medela pump. It’s compact and portable, and the ideal fit for four Medela storage bottles. The ice pack ensures that your bottles of milk won’t go tumbling around the bag. However, some mums wish that it’s slightly bigger, especially the mums who express more than twice a day might find this bag a bit too small.

Apple and Mint Lunch Bags

It does have a mesh pocket and seams inside the lunch bag, I did find this hard to keep clean.

This space-age thermal batting from The Warm Company was originally designed for insulating air conditioning ducts or wrapping your hot water heater (for which it’s very effective). But Insul-Shine is actually quite sewable.

You can make something simple, like a reflective visor for your car or to put in your RV windows to prevent sun damage. If you’re looking for a mod metallic look, you could also use it to cover a headboard, throw pillows, or make a budding astronaut very happy with some rocket wall art.

Insul-Shine has two layers, reflective material and insulating polyester batting. The metal surface wipes clean and actually acts as a water barrier for soft coolers, diaper bags, and bottle carriers.

It is washable, but doing this may dull the reflective side. Sold in 22″ and 45″ widths.

Iron Quick

Neither Iron Quick products should ever be used in the microwave.

Both can be machine washed but should then be air dried – not tossed in the dryer. You can also use a damp cloth to wipe clean.

Nancy’s Notions carries both types of Iron Quick products by the yard.


Back in the 1980s, the 3M Company introduced an amazing new insulating material called Thinsulate. Ounce for ounce it had one and a half times the warmth of down and twice the warmth of other high-loft insulation materials. It meant you could get sleek ski gloves that were just as warm as giant, puffy mittens.

A quarter century later, Thinsulate is still amazing. Made from microfibers that are only a tenth the size of of other synthetic insulation, it’s much more effective at reflecting back heat. And Thinsulate absorbs less than 1% of its weight in water, allowing it to retain its insulating ability even in damp conditions. You can use it in any kind of project where you want to keep warm but don’t want a lot of bulk, such as jackets and blankets.

You can get varying densities of Thinsulate, depending on the weight and R-value (insulating property) you want, from 1.up to 2.9.

Thinsulate is machine washable and dry cleanable once you have sewn it inside your project. It is a bit tough to find as yardage, but we did locate Thinsulate online at Vogue Fabric Store and The Rain Shed. It’s available by the yard, 60″ wide.


Wrap-N-Zap by Pellon is the only thermal product mentioned on this page that we can safely declare to be microwave safe. It’s got Zap in its name and it says “Microwave Friendly!” right on the package.

Made from 100% cotton batting, without glues or other chemicals that could leach into foods, Wrap-N-Zap is designed for projects like insulated baked potato bags and casserole warmers – situations where you heat up the food inside the cover and leave the cover on to keep food warm.

We found it in a 45″ x yard package at Joann Fabric and Nancy’s Notions.

Thermal fabrics are a “hot” trend
