Arctic Zone Titan Deep Freeze Hardbody Cooler

Arctic Zone beer cooler is another user-friendly lunch box we had to include in our list. This product works differently compared to other lunch boxes we have reviewed so far, but it delivers the same results. Rather than prevent temperature escape by absorption, Arctic Zone insulated body reflects heat using a unique barrier fitted to the interior. This barrier ensures that the compartment remains warm, which in turn keeps your food warm. It has a patented flip opener without zippers that allow you to access your food and drinks. Furthermore, the Hardbody liner is made with FDA compliant materials. The removable smart shelf is another feature you will appreciate.

Arctic Zone is leak-proof with an insulated leak-proof pocket in front of the box. The interior lining is very easy to clean, and so is the exterior. The exterior is covered with Rhino-tech stain and water-resistant materials that will not scratch or crack even when placed on a rough surface. This is one of the best lunch boxes you should go for if you are on a low budget but desire an effective and long-lasting box for your food.

Let us also point out that the SmartShelf allows you to store hard items like drink bottles and cans away from delicate items, so they don’t get crushed. If you want to use the entire box in a single compartment, you can remove the SmartShelf for a single large interior space.

Insulated Lunch Boxes Buyer’s Guide

What are the essential features to look out for when searching for an insulated lunch box to buy? We discuss some of them below.


You want to make sure that the lunch box has more than enough storage space to hold your desired items. Avoid buying a box that is too big simply because you are space conscious neither should you buy a box with limited storage space. Determine the contents you wish to place in them before you place your order.


We recommend a lunch box with at least 2 compartments. Different compartments allow you to store soft and hard items separately. If the lunch box only has a single compartment, some of the items you store in it will be ruined. Two or more components also allow you to store hot and cold food separately.


Be mindful of the weight of the box. If your box is too heavy, you will not be willing to use it as often as you should. The best insulated lunch boxes are portable and lightweight. They are also easy on the shoulder and do not cause shoulder sprains.
