Important Features of a Good Insulated Lunch Box
It’s essential to find a lunch box that will last. If you’re getting a new lunch box, you don’t want to spend $20 on a product you’re just going to replace a couple years down the road. Having a durable lunch bag is one of the essential features to look for. The more durable, the less chance you have of the warm or cold air leaking out.
2. Proper Insulation
On our list, we reviewed 5 insulated lunch bags with proper insulation that can keep your food at the desired temperature. Many insulated lunch boxes utilize material that doesn’t work as well as it claims, so you’ll want to make sure the product you’re buying can keep your food fresh. Many good lunch boxes use PEVA lining or an aluminum polyester blend, which keeps food fresh and is easy to clean.
3. Plenty of Storage
Having multiple compartments may allow you to create different sections. If the insulation is dispersed correctly, you might be able to keep hot food in one section and cold food in another. On top of that, multiple compartments help with storage and enables you to put more in your lunch box.

Most lunch boxes are used to allow you lunch on the go. Having the ability to carry your lunch box without worrying about a broken shoulder strap or a ripped zipper is important.

1. MIER Adult Insulated Lunch Box
The MIER is all about providing ample storage in a small container. It comes with a soft pu handle and a detachable shoulder strap which makes the bag easy to carry. The bag includes two separate compartments for food storage – an upper and a lower main compartment – each with proper insulation and bpa free liner to keep your items hot or cold throughout the day. There is a front pocket for utensils or napkin storage as well. The lining of the insulated lunch bag is insulated PEVA, which is both eco-friendly and easy to clean. With dimensions of 10.2″ by 7.9″ by 11″, you’ll have more room than you’ll need.
Our Honest Review
MIER is a trusted name in the lunch box world for a reason. Their products are always dependable and high quality, with this box being no different. This might be their best box yet even, as the maximum amount of storage space in such a compact device is unbelievable. The dual compartment storage offers you enough space to host two different meals at once, while the insulation allows you to keep them at different temperatures without cross over.
Along with insulation, this bag offers one of the easiest cleans you’ll encounter. The PEVA interior lining is stain-resistant and easy to wipe. Any spill comes right off with the swipe of a paper towel or napkin. Speaking of napkins and paper towels, the ample storage space in this insulated bag allows you to store your utensils and napkins in separate pouches, further preventing any cross over.
We did encounter a couple of durability issues while using this lunch box, mainly along the creases of the zipper. Some threads snapped under a decent amount of pressure, but very few situations would lead to that occurring to your lunch box. Overall, this is the best-insulated lunch box we have tested. The space alone is almost unmatched relative to its overall size.
2. OPUX Premium Lunch Box
Much like the MIER Adult Lunch Box, the OPUX Premium uses PEVA insulated lining to keep the environment steady. The PEVA lining is also quite simple to clean out and is leak-resistant. With side pockets for your water bottle and utensils, this device focuses on your food for interior storage. Durability along the zipper is reinforced with high-quality nylon and 600D polyester, which prevents rips and keeps your lunch box active for years to come.
Our Honest Review
The strength of this insulated lunch bag is surprising. When we first picked up this product, we saw the main compartment and figured it would lead to external compromises — we were wrong—the fabric used in the construction of this product allowed for ample interior storage without the threat of ripping. The zipper was sturdy, and the lining surrounding it was as well.
The insulation this product provides is fantastic for keeping your food warm — the PEVA interior is once again easy to clean out if spills ever occurred. Our favorite aspect of this product was how simple it was to carry it around. The sewn-in shoulder strap makes the bag easy to carry.
Our one issue with this product was the flimsy walls. While the zippers and creasing around the exterior were durable and sturdy, the lack of structure made protecting your food difficult. One wrong placement and the lunch box would smash your sandwich. It has room for a small ice pack to keep ice packs to keep your lunch cooler throughout the day. Its size is excellent for long-distance traveling, and the design is simple to clean out if spills do occur.
3. MAZFORCE Original Lunch Box
The MAZFORCE is all about the design. This lunch bag is perfect for the active professional who needs lunch on the go in a sophisticated and office-friendly design. The foam core technology keeps your food temperature for hours and supports easy clean-ups. The slim back and side pockets and stretchy interior mesh offers you as much space as possible in this compact lunch container. MAZFORCE tests all of their products and guarantees this box will stand up to the elements – it’s waterproof and heatproof.
Our Honest Review
In a similar style to the MIER Adult Lunch Box, we were shocked to see how much this small container could fit. It stretches when it needs to, but not too much to the point where it can’t be closed and zipped correctly. The large interior mesh pockets allow you to pack in your snacks and keep as much room left over for the big containers. MAZFORCE focused on providing you with as much space as you need for lunch throughout the day.
Our favorite aspect of this bag has to be the professional and sleek design. Though it has no bearings on the performance of the product, it’s essential to have a lunch box that works well in an office setting. Even the insulated interior is designed to be presentable. It keeps your food at the desired temperature for hours and offers a waterproof and leak proof solution to spills and messes.
While the bag is undoubtedly made of excellent PVC and BPA free materials and is built to last, be gentle with the zipper. With this bag you may have found yourself the perfect insulated lunch box. The storage space available for this tiny and lightweight box is incredible. The side pocket is big enough to hold a water bottle.
4. Carhartt Deluxe Insulated Lunch Bag
This is another dual compartment insulated lunch bag with a main compartment in the body and a secondary one in the top. The Carhartt Deluxe insulated lunch bag includes a mesh wall to help separate the two separate compartments and a front pocket to help store utensils and napkins. The case is 100% synthetic material, which stands up to the elements and is water repellent. With a sturdy insulated interior, this bag is large and can hold an entire 6-pack of beer in the body compartment alone, leaving room at the top.
Our Honest Review
Carhartt knows how to make a durable outdoor tool. From jackets to large lunch boxes, they’ve always been a leading name in durability and dependability. This insulated lunch bag shows a focus on keeping up the Carhartt name with the recognizable orange exterior, which is water-resistant and supports long-lasting use. When you see the Carhartt orange, you know it’s a lasting product.
The large interior space is excellent as it offers separation between compartments and supports the storage of multiple meals. Their claim that the bottom could host an entire 6-pack was true, though you do lose some of the headspace making further storage difficult. The insulation on this bag is fantastic as it keeps your items their temperature regardless of the external environment.
Though the insulated lunch bag is on the smaller end, the front pocket helps to alleviate the pressure of finding space. Having a separate spot for storing your utensils and napkins is never a bad thing, and Carhartt implements that here. It is a one size fits all design as the shoulder strap isn’t adjustable, but it’s lightweight and easy to carry otherwise. If you’re looking for a durable and dependable lunch box, Carhartt has your back.
5. Wildkin Lunch Box, Whale Blue
The Wildkin lunch bag ensures safety for you or your kids while using the product. The materials in the box are PVC, BPA, and Phthalate free. The quality and safety of this box were enough to win it a Mom’s Choice Award. Admittedly small, this insulated lunch bag is perfect for transport – you can easily store it away without worrying about crushing or bending it. The interior is a classic lunch box design with a large main compartment and a mesh pocket to hold your ice packs or utensils.
Our Honest Review
Just because there’s a focus on the kids with this product doesn’t mean it’s not great for adults as well. This box fantastic for all ages and sizes in terms of design alone – you can choose a base color like Whale Blue, or you can customize with cooler designs and crazy animals. Wildkin has designed the perfect insulated lunch bag for kids and adults alike.
This lunch box is perfect for the person on the go looking for a one meal storage option. The size is small enough that it can be stored away easily without taking up too much space yet is still able to hold a decent-sized container and a small ice pack to keep your food cooler. Wildkin uses premium quality fabric to ensure that this insulated lunch bag will remain in use for years. We loved how easy it was to clean this bag if spills ever occurred, and the insulation keeps your food and ice packs cooler throughout the day.
If you’re looking for a compact and easy to transport lunch box, then this is a fantastic product for you. It makes lunch fun again and can keep food safe from harmful products that other boxes use. The exterior is durable and will keep food safe from being crushed while the interior keeps it fresh all day long.
6. Lifewit Insulated Adult Lunch Box
The Lifewit insulated lunch box uses seamless hot pressing on the interior insulated walls. This prevents the tearing of any seams, which can lead to leaks and compromised insulation on other products as there are no seams to break. The insulated PEVA interior guarantees freshness for up to five hours. 6mm EPE foam prevents damage from occurring to your items. The exterior is both water and dirt proof and is easy to clean.
Our Honest Review
A decently new trend, and still rare to encounter, this bag uses seamless hot pressing to remove the chance of the interior walls tearing. The last thing that will happen to this box will be the tearing of the interior. We love knowing that our food will be insulated and fresh all day long without a chance of temperature or liquid leaking.
The interior might seem like the heavy lifter of this product, but the outside carries its weight as well. Being made out of 600D water, dirt and leak proof Oxford fabric, this large box is one of the most durable on our list. It won’t be compromised on the outside from the elements, and it protected on the side from spills and leaks. Lifewit placed their focus on creating an insulated lunch bag that will be the last one you buy.
Although we adore the durability of this product, it does struggle to hold its shape and can fall in on itself if not packed correctly. Other than the internal structure of the product, this is a fantastic large lunch box for anyone working on the go in need of a way to keep food fresh all day long.
7. UPPER ORDER Durable Insulated Lunch Box
We think this is the best insulated bag for many reasons. One issue that many lunch bags seem to encounter is easily compromised zippers. UPPER ORDER designed their lunch box with a made-to-last zipper that works with you and can withstand continuous, rigorous usage. It comes with a wide shoulder strap that contains an adjustable padded cushion. The interior material is heavy-duty polyester aluminum foil, which helps keep your lunch fresh and prevents rips and compromises. The exterior pocket is perfect for storing away your phone, pens, and other work materials during the day.
Our Honest Review
Our favorite part of this lunch bag has to be the interior. It’s quite a unique pattern from the rest of the bags on this list and uses a different material for insulation. The polyester aluminum lining keeps your food cold or warm for hours before it even starts to even out. With this material, you receive a sturdy and durable interior lining that is resistant to rips and tears. The mesh can hold for slim ice packs to keep your lunch cooler.
There’s nothing more frustrating than having your zipper break off of your lunch box or having the zip track open, ruining the whole box. With this made-to-last zipper, you won’t have to worry about that. The zipper stays on the track no matter how often you use the insulated lunch bag. Along with the durable zipper comes the durable shoulder strap, which is invaluable to assisting in easy transport of this lunch box.
Though this is a bigger model than their previous versions, the space available is lacking. It’s great for a one meal experience, but for anyone looking to pack multiple meals, you might be left wanting with this product. Besides the lack of space, this is a fantastic insulated bag that works to be both durable and dependable.
There is not only one unmatched champion of insulated lunch boxes – each product has unique features and designs, and what works best for one person might not work for another. Each lunch box on our list surpasses industry standards in terms of quality and dependability. The boxes on our list are our favorite options and are of the utmost quality.
Many different companies make unique, insulated lunch bags. Some of the best insulated bags are from MIER or Wildkin. Carhartt also is a reputable name when it comes to durability.
