Packing lunch for work only sticks if the gear doesn't fight you. Serious Eats shook bento boxes full of water, microwaved spaghetti in them and painted them with sauce, then left lunch bags full of ice on a table for a full eight-hour workday.
Its food thermoses had to keep boiling soup above 140°F, and Food Network's value pick held soup there for six hours. Reviewed's adult lunch bag rounds out the budget end, and Serious Eats' reusable bags replace the plastic baggies. Start with a bento box and a lunch bag. Add a thermos if your office microwave line is a whole situation. Each card shows the drawback the testers called out, like lids that take real effort to open.
Who this is not for. Skip this if you want the whole Sunday meal-prep setup; the Meal Prep list has the glass containers, rice cookers and sheet pans.

budget pick · 4-pack
Best for a box for every day of the week
Serious Eats' best budget bento box: four wheat-straw boxes that each fit a standard sandwich plus two sides, and they nest inside each other for storage.
Heads up. They won't last as long as the other picks, and they stained when leftovers were microwaved in them

Best for hot lunches when the office microwave line is long
Serious Eats' best food thermos for hot food: it kept chicken noodle soup hot for five hours, and the whole thing can go on the top rack of the dishwasher.

Best for soup without a microwave
Food Network's best value food thermos: slim enough for any lunch bag, and hot soup stayed above 140°F even after six hours in reviews.
Heads up. The finish scratches off easily, and deep crevices in the lid can trap food

mid pick · 16 oz
Best for chili, stew and soup days
Serious Eats' best classic food thermos: it matched the top pick by keeping soup hot for five hours, and a sturdy folding steel spoon tucks into the stopper.
Heads up. The narrow mouth makes ladling soup in tricky, and it picked up dings when dropped

Best reusable bagsmid pick · 5 bags
Best for snacks, cut fruit and sandwiches
Serious Eats' best reusable food bags: thin enough to fold into a drawer, sturdy enough to stand up on their own, and they didn't leak.
Heads up. The thin material may rip or get holes over time, and it shows stains more than silicone

Best for swapping out plastic baggies for good
Serious Eats' best reusable silicone bags: the best size range of the thick silicone bags, minimal staining, and they've lasted over a year in long-term reviews.
Heads up. The thick seal is harder to close, and it spilled when flipped and shaken hard

Usually not, but the Bentgo MicroSteel is the exception: Serious Eats found it microwave-safe and durable. Most other metal boxes it reviewed, like the S'well and Black+Blum, aren't, so plastic boxes like the Buluker or Takenaka make more sense if you reheat leftovers every day.
In Serious Eats' test, the Simple Modern Provision and Thermos Stainless King kept soup above 140°F for five hours, and Food Network's Mira kept it there for six. Serious Eats found narrow, taller jars held heat best, and that none of the thermoses kept cold egg salad below 40°F for more than two hours.
Fuller bags do best. In Serious Eats' eight-hour test, the Bentgo Insulated Lunch Bag lost only six ounces of ice, while big cooler-style bags struggled to keep a small amount of ice frozen; Serious Eats says they work better when fuller. Pack it full or add an ice pack.
