You know that feeling when you've finally prepped a decent meal, but you're dreading putting it into a cheap, flimsy bag that looks like it belongs in a middle school cafeteria? It’s annoying. Honestly, most lunch containers are either aggressively "outdoorsy" with way too many clips or they’re just poorly made plastic sacks that leak the moment your Tupperware tips over. That’s usually where people start looking at a Herschel Supply lunch bag.
It’s a weirdly specific cult favorite.
Herschel started in 2009. Jamie and Lyndon Cormack named it after the tiny town in Saskatchewan where three generations of their family grew up. Since then, they've basically taken over the "attainable heritage" aesthetic. You see their backpacks everywhere—from university campuses in Vancouver to subways in London. But their lunch bags, specifically the Pop Quiz Lunch Box and the Kaslo, have a specific reputation for being the "grown-up" choice that doesn't feel boring. They’re built for people who want their gear to match their outfit but actually need their salad to stay cold until 1:00 PM.
What Most People Get Wrong About These Bags
There is a common misconception that Herschel is all about the look. People assume it’s just a canvas bag with a logo. It's not.
If you actually open one up, the first thing you notice is the insulation. It’s a BPA-free, wipeable lining. It feels different than the thin, crinkly silver foil you find in supermarket coolers. It’s thick. It’s meant to handle the inevitable yogurt spill. Most users don't realize that the "Pop Quiz" model actually uses a reinforced handle because the founders realized that lunch bags get swung around more than backpacks.
Is it a professional cooler? No. If you're going on a three-day trek in the desert, buy a Yeti. But for a Tuesday at the office or a picnic at the park, it hits a sweet spot. It’s about utility without the "tacticool" overkill.
The Construction Reality
The exterior is usually their signature 600D polyester. That’s a heavy-duty weave. It’s resistant to abrasions, which matters because lunch bags spend half their lives on the floor or crammed into a communal fridge.

One thing that really stands out is the zipper. Most cheap bags use plastic teeth that snag the moment a stray crumb gets in the way. Herschel tends to use waterproof zippers or heavy-gauge metal ones with pebbled leather pulls. It sounds like a small detail. It’s actually huge. A broken zipper makes the whole bag useless, and Herschel’s hardware is designed to outlast the fabric itself.
The Pop Quiz vs. The Personal Cooler
If you're shopping for a Herschel Supply lunch bag, you're probably choosing between two or three specific shapes.
The Pop Quiz Lunch Box is the flagship. It’s rectangular, structured, and has a separate front pocket. This is vital. Why? Because you shouldn't put your cutlery or your phone or a napkin in the same cold compartment as a sweating bottle of water. Everything gets damp. The separate pocket keeps your dry stuff dry.
Then there’s the Kaslo. It’s part of their Tech line. It feels a bit more "commuter" and often features recycled materials. It’s sleeker. If you’re wearing a suit or a sharp blazer, the Pop Quiz might look a little too "campus," whereas the Kaslo fits the corporate aesthetic.
Then you have the Heritage models. These are basically miniature versions of their famous backpacks. They have that classic diamond-shaped "lash tab" (the "pig snout") on the front. On a backpack, that’s for tying on gear. On a lunch bag? It’s purely for the vibe. And honestly, that’s okay.
Does It Actually Keep Food Cold?
Let's be real: insulation is only as good as the ice pack you put inside.

A Herschel Supply lunch bag isn't a vacuum-sealed thermos. It’s an insulated sleeve. In real-world testing—think a standard office environment or a car interior—you can expect your food to stay at a safe temperature for about 4 to 5 hours with a decent gel pack. If you’re throwing a warm sandwich in there with no cooling element and expecting it to stay fresh until dinner, you’re going to be disappointed.
The lining is the hero here. It's leak-resistant, not leak-proof. If a whole container of soup opens up, it will eventually find its way through the seams. But for minor condensation or a rogue grape juice drip? You just wipe it out with a damp cloth and you’re good to go.
Why the Price Tag Varies
You’ll see these bags ranging from $30 to $50. Sometimes you’ll find them on sale for $20. The price difference usually comes down to the "Eco" line.
Herschel has been moving toward using 100% recycled fabrics from water bottles. It’s a massive shift for the company. The "Eco" versions feel slightly different—a bit more textured, maybe a little stiffer—but they serve the same purpose. Buying the recycled version is generally the better move for longevity, as the newer fabrics are incredibly tough.
The Practical Side of Maintenance
I've seen people throw these in the washing machine. Please, don't do that.
The heat and the agitation of a washing machine can delaminate the interior lining. Once that silver/white waterproof layer starts to crack, the bag loses its insulating properties. Instead, use a mix of mild soap and warm water. If it smells—and lunch bags always eventually smell like old ham—use a bit of baking soda.

- Step 1: Turn it inside out.
- Step 2: Wipe it down.
- Step 3: Let it air dry completely.
If you zip it up while it’s still damp, you’re basically inviting mold to move in. Give it a night to breathe on the counter.
Is It Worth the Hype?
It depends on what you value.
If you want the absolute highest thermal efficiency, you might want to look at brands like Stanley or Pelican. They are heavy, bulky, and look like they belong on a construction site.
But if you want something that fits in a backpack, looks professional, and won't fall apart after three months of daily use, the Herschel Supply lunch bag is a very solid investment. It’s a style statement that actually works. Most people keep these bags for years. They don't really "go out of style" because the design is so rooted in classic mountaineering aesthetics.
Key Takeaways for Your Next Purchase
When you're ready to buy, look closely at the dimensions. The Pop Quiz is surprisingly deep; it can hold a standard glass meal prep container plus a fruit and a drink. The smaller "Lunch Box" models are better for kids or light snackers.
Also, check the handle. Some newer models have a clip-on handle, which is a lifesaver. It means you can clip the lunch bag to the outside of your backpack, saving that precious internal space for your laptop and notebooks.
Actionable Next Steps
- Measure your containers: Before buying, measure your favorite Tupperware. Ensure the bag’s internal height (usually around 7-8 inches) accommodates your stack.
- Choose the Eco line: If available, opt for the "Eco" versions made from recycled bottles. They have better resale value and are objectively better for the environment.
- Get a slim ice pack: Because these bags are structured, thick "brick" ice packs take up too much room. Look for the flat, sheet-style gel packs to maximize food space.
- Inspect the zipper: When your bag arrives, run the zipper back and forth ten times. It should be smooth. If it catches on the interior lining out of the box, exchange it immediately.
