21 Best Lunch Boxes for Adults (Updated!)

1. 1. Stanley Classic Large Capacity Steel Lunch Box

   

   Price: $50.00

   Amazon Customer Reviews

   Shop at Amazon
   Pros:

   • Big and roomy enough to hold lunch and more
   • Top bracket securely holds and insulated bottle
   • Virtually bomb proof metal exterior looks better with use
   • Retro cool styling with a lifetime guarantee

   Cons:

   • Too big for some
   • Thermos bracket is a bit flimsy
   • Need to get the large capacity to fit an insulated bottle
   • More spendy than many

   Isn’t it funny how sometimes the old school lunch box can come back into vogue after decades of being somewhat off most consumers’ radar? This big and beefy metal lunch box is totally retro cool, and similar to the ones your dad and grandpa probably used to take to work. Mine sure did. The durable metal exterior means this lunch box can take a beating in the rugged outdoors, so the occasional bump or drop is only going to give it more character.

   It secures with sturdy metal latches in front, and when opened features a huge roomy main compartment on the bottom that can easily hold multiple sandwiches or food containers as well as fruit, veggies and more. The domed top has a metal bracket that secures a Stanley insulated bottle, or your own water bottle. 

   These adult lunch boxes are virtually bomb-proof, and my evidence for that is a husband who is still using one from the 50s – a gift from our daughter who found it at the thrift store about 15 years ago.

The durable water-repellant fabric exterior is made to handle rigorous treatment on the job site while keeping a large lunch cool throughout the day.

   Dual compartments, one in the main bag and one in the lid, allow for storage of up to six cans of soda, or several food containers and blue ice as well. The rounded top is reminscent of an old school metal lunch box and is large enough to hold fruit, chips or a water bottle and has a mesh bottom so it’s easy to see what you’ve stowed up there. 

   The front zipper pocket is perfect for utensils and a few paper towels or wet wipes for post-meal cleanup. This insulated lunch box comes with an easy carry handle as well as a convenient shoulder strap. The sturdy YKK zippers will easily hold up to the rugged use this cooler will likely endure. 

   For those who prefer a more moderately sized adult lunch box in a tradition rectangle shape, Carhartt makes a popular one of those as well.

   So many soft-sided lunch boxes for adults simply don’t cut it when it comes to protecting your food. That’s why we think you’ll love this upright lunch box from Columbia. Of course, it’s made to be super tough, just like all of Columbia’s rugged outdoor gear, but this lunch box has a hidden secret inside – a hard liner that keeps your food from ending up like a mashed up mess.

   This removable liner has an adjustable divider so you can fit things individually depending on what you want to pack each day. Because of its narrower upright profile, you can slide it into a cramped office fridge or add an ice pack and slip it right under your desk, thanks to the high density thermal insulation. 

   The zippered lid features a mesh pocket to store your smalls, and it features a super comfy padded handle for easy carrying, as well as an adjustable shoulder strap. If you need an even larger space for food storage the Columbia Grid Line Expandable Lunch Pack might be a better option. The Columbia Superior Summit Expandable Lunch Pack gives you a few more insulated storage pouches as well as a mesh bottle holder.

This bento lunch jar is a great option for an adult who prefers smaller portions sizes. With two insulated and sealed containers, one that measures about 1.25 cups, and one that measures about 2.5 cups, this bento jar can store soups, stews or pasta in the bottom, and a cool crunchy salad or fruit in the top.

    With each section screwing into the next, this insulated jar keeps foods from spilling and contaminating one another. The convenient carry handle is a total bonus and this cutie comes with two fruit forks that can be used for any main dish or side that’s not too liquid. Made with BPA free plastic and food grade stainless steel, this durable option is also quite a bit more affordable than the other bento jar we reviewed here.

    For larger lunchables, consider the three container bento jar that offers two 1.25 cup sections along with the 2.5 cup container. You can also get a padded carrying case with a shoulder strap to leave your hands free if you happen to use mass transit for your commute.

    If you’re serious when it comes to packing a lunch box that can carry enough food to last from morning until night, this seven quart Stanley cooler is meant for you. With hard sides, you don’t have to worry about tossing it in your work truck or patrol car, and the divided interior gives you tons of room for ice, drinks, sandwiches and more.

    The foam insulation keeps foods cool all day long, and the removable lid can be used like a portable table to set your drinks and food on top of. The biggie here is that this substantial lunch cooler comes with the classic Stanley 1.1 quart vacuum seal bottle. The screw off lid can be used as an eight ounce cup, and it’ll keep coffee hot or ice water cold for a whopping 24 hours.

    Double insulated and made of durable stainless steel, the bottle locks in place on the top of the cooler to be sure both your food and your drinks arrive safely at the same time.
