Best Lunch Box for Keeping Meal Prep Cold at Work

I do not have access to a fridge at my new job and I am worried about my meal prep going bad during the day. I am looking for the best insulated lunch box that can keep my food cold for at least six to eight hours.

I have seen some heavy duty ones like Yeti but they are very expensive. Are there any more affordable brands that work just as well? I am also looking for a lunch box that is large enough to hold two or three containers plus some snacks. I am based in Canada and the summers can get quite warm.

Does anyone have a recommendation for a lunch box that actually stays cold? I have tried the cheap ones from the supermarket but they only last a couple of hours. I would appreciate any advice on how to keep my food safe and fresh at work!

I've been in that exact spot when I was working on-site at a warehouse in London. Your best bet is definitely a PackIt Freezable Lunch Bag. The cooling gel is built into the walls of the bag, so you just fold the whole thing up and stick it in the freezer overnight. It keeps my chicken and veg cold until at least 2pm.

I have been looking into the PackIt ones myself, but are they durable enough for a construction site or a rugged office environment? I’m worried about the gel leaking if it gets tossed around too much.

If you want something heavy-duty, look at the Yeti Daytrip Lunch Box. It is pretty pricey—about $80 USD—but the insulation is insane. I’m in Texas where the heat is no joke, and I can leave this in my truck for a few hours and the contents stay fridge-cold.

I second the Yeti! It's a bit of an investment, but the build quality is far better than the cheap nylon bags you find at the supermarket. Plus, it's easy to wipe down if your meal prep containers leak a bit of sauce.

$80 for a lunch box? That’s nearly £65! Seems a bit steep just to keep a salad cold. I use a standard insulated bag from John Lewis and just shove two high-quality ice bricks in there. Does the job perfectly for my commute into Leeds.

The ice bricks are key, but make sure you get the hard plastic ones, not the gel packs. The gel packs sweat way too much and you end up with a soggy bag. I’m in Toronto and even in the summer, a decent Arctic Zone Titan bag keeps my high-protein meals safe all day.

Thanks for the suggestions! The Yeti looks cool but might be out of my budget. VancouverDave, does the Arctic Zone have a shoulder strap? I walk about 15 minutes from the subway and don't want to carry it by hand.

Yes, most of the Titan Deep Freeze models come with a strap. They also have a 'hardbody' liner that stops your food from getting crushed in your backpack or on the train.

I actually just saw a review of the Igloo MaxCold bags. They are much cheaper than Yeti but supposedly hold ice for up to two days. Might be a good middle ground for you, OfficeWorker.

Don't forget that the container itself matters too. If you use glass meal prep containers, they hold the cold temperature much longer than cheap plastic ones. It’s physics, isn't it? Thermal mass and all that.

Glass is great but so heavy to carry in a flat! I stick to BPA-free plastic but I pre-chill my food in the fridge overnight. If the food starts cold, the bag has less work to do.

Totally agree with pre-chilling. Also, try to keep the lunch box away from windows or heaters at work. Even the best Yeti won't help much if it's sitting in direct sunlight on your desk.

Has anyone tried those electric lunch boxes that you plug in? I keep seeing ads for them on social media.

Those are usually for heating food up, not keeping it cold. Unless there's a new Peltier-cooled version out there, I’d stick to passive insulation for cooling.

Wait, I found one! Cooluli makes tiny portable fridges that sit on your desk and plug into a USB or wall outlet. Probably too small for big meal prep containers though.

Yeah, those 'mini fridges' are mostly for skincare or a single can of diet coke. Not really practical for a proper tupperware of chicken and rice.

I think I’m leaning towards the Arctic Zone. It seems like a solid Canadian brand and the price is right for me. Does it fit into a standard gym bag?

It's a bit bulky, but if you have a decent sized bag it should be fine. Just check the dimensions before you buy—they have different 'can' sizes.

Actually, for anyone in the UK reading this, the Decathlon cooler bags are incredible value. They are designed for hiking but I use one for work and it’s very durable.
