Depending on the people you work with, the office refrigerator might not be a safe place for your lunch. (How anyone can “mistake” your lovingly assembled kale salad for their #saddesklunch is beyond us!). Or maybe your job has you on the road most of the day, driving back and forth to appointments, and you don’t have access to a fridge? Or maybe you just have a long commute? Either way, you need a lunch box that’ll keep your food cold. Like, really cold. For a long time. These lunch boxes will keep their cool until you’re ready to eat. The best part? They’re pretty stylish to boot.

Dagne Dover

Dagne Dover is a beloved name in the travel industry, so it makes sense that their lunch box would be equally as functional (not to mention stylish). Made from their signature neoprene, this roomy and insulated pack boasts mesh pocks inside to keep utensils or smaller snacks organized. The best part? It's made from four recycled bottles, so it's a purchase you can feel good about.

Modern Picnic

If looking pulled together 24/7 is your office M.O., you'll want to snag this lunch bag from Modern Picnic. We say lunch bag, but really it's more like a luxe purse that happens to boast an insulated interior. The true magic shines on the exterior, with faux croc leather, multiple straps, and a classic boxy shape reminiscent of some of the best designer purses.

Put this bag (and all the other PackIt bags) in the freezer overnight to activate its built-in freezable gel. When you wake up, the walls of the bag will be frozen and ready to keep your food cold for up to 10 hours. This easy-carry bag has a pair of handy straps and plenty of interior room for your lunch plus plenty of snacks.

This puffer lunchbox is so charming, it doubles as a trendy accessory — and one that you won't mind toting out in the open on your way to work. The exterior is made from durable (and waterproof!) polyester, which folds flat for easy storage. The roomy interior boasts plenty of room for food storage containers, ice packs, and more.

For people who are serious about their lunch (or drink smoothies all day long?), there's no better brand to turn to than Yeti. The company has a cult following because many campers and hunters insist their (expensive) coolers are the best. This lunch box is meant for day-long wilderness expeditions, so you know it'll be able to handle your work day.

was $29.99

Coleman says this lunch bag will keep contents cold for 24 hours in 90-degree heat. We've used it for a workday and had zero complaints. Bonus: It's big enough to hold a large lunch with a few drinks, but it's not so big and bulky that it's awkward to tote around during a commute.

L.L. Bean

Technically meant for kids, the solid colors on this LL Bean lunch box make for legit options for adults, too. This particular lunch box keeps food cold for hours while staying compact enough to squish into a backpack, purse, or your already-cramped office refrigerator.
