SIGG Gemstone Food Jar & Food Box
When it comes to eating outdoors, whether that’s halfway up a soggy hillside, perched on the tailgate of a pickup, or simply hiding from Colin in accounts in your office kitchenette, you want kit that’s reliable. Not “influencer reliable”, but actually trustworthy. The sort of gear that’ll survive being kicked about in the boot, dropped on gravel, and occasionally used as a tripod for a camping brew shot.
Fortunately, SIGG has built its entire reputation on that sort of dependability. Founded over a century ago and beloved by hikers, climbers, school kids, and hipster commuters alike, SIGG’s metal bottles and food containers are the kind of kit that quietly get on with the job. No fuss. No leaks. No lingering aroma from last month’s chilli.
So when their Gemstone Food Jar and Gemstone Food Box landed on our doorstep, we were already expecting good things. Spoiler: they delivered.
First Impressions - Shiny, Solid, and Sensible
SIGG’s Gemstone line is designed to look premium without going all “Instagram wilderness influencer”, and they’ve nailed it. Both the food box and the food jar feel like they’ve been carved from the kind of stone you’d build a temple with, smooth, solid, with a matte finish that hides fingerprints better than most of the SUVs we test.
The 0.75ltr Food Jar is double-walled stainless steel and nicely compact, small enough to chuck in a daypack, big enough to hold a proper portion of stew, curry, pasta, or soup. The 1.1ltr Food Box, on the other hand, is a neat rectangle designed for salads, sandwiches, leftovers, or, if you’re like me, a questionable assortment of cheese, crackers, and emergency pork pies.
Out in the Wild - Warm Food, Happy Humans
I took the Gemstone Food Jar on a couple of muddy rambles and a green-lane afternoon that turned into an accidental four-hour trek. I filled it with homemade chilli (the kind that could strip paint) and set off. Several hours later, in a lay-by overlooking a soggy field, I cracked it open and… still hot. Not lava-hot, but very-eatably warm. Perfect. In fact, it’s designed to keep things hot for 14-hours, and ice cold for 20-hours.
The mouth is wide enough to eat from comfortably without redecorating your trousers, and the shape sits nicely in a gloved hand. It’s also surprisingly easy to clean, no narrow corners for rogue grains of rice to hide.
A bonus is that the lid doubles as a shallow bowl if you’re feeling posh, and the vacuum-stopper contains a folding stainless steel spork - though I wish it was made from plastic as it would scrape as much when you’re ferreting for that last mouthful.
As for the leak-proof Food Box, this thing is a winner for alfresco snacking. Although it’s incredibly lightweight, it’s also sturdy. With clips on both sides of the box securing the lid to the body you can feel safe in the knowledge that the box won’t pop open when squeezed inside a rucksack, and it shrugged off both the mud and a light shower. We dropped it (accidentally, not scientifically) and the only victim was the pork pie inside. RIP.
While SIGG doesn’t claim the Food Box is insulated, the seal does a good job of keeping smells in and weather out. Sandwiches stayed fresh, cheese stayed un-sweaty, and nothing tasted like damp grass, which is more than can be said for some containers we’ve tested. Oh, it also comes with an 18/8 stainless steel divider to keep things separate.
Back in the Office - Civilised Eating (Sort Of)
Once back in civilisation, or at least as civilised as our home office gets, the Gemstone pair proved just as useful.
The Food Jar kept soup warm until lunchtime without drama, and crucially, it didn’t leak a single drop into a rucksack, laptop bag, or the passenger seat of the latest press car. That alone should earn it an award.
The Food Box fits nicely in a messenger bag, and even a cubby box between seats, and looks smart enough that even corporate types won’t sneer at it. We used it for sandwiches, carrot sticks (let’s pretend), and leftover pasta. Again: no leaks, no odours, no fuss.
You could argue that buying premium lunch containers for office life is overkill - and you’d be right, but after years of cheap boxes turning the inside of our bags into a Jackson Pollock tribute, we’ll take SIGG’s overkill any day.
Durability & Usability - Built Like a Tank, Acts Like a Butler
SIGG products have always felt over-engineered in the best possible way, and the Gemstone series continues that tradition. The metal body resists dents surprisingly well, and the seals feel durable rather than delicate.
Verdict - Simple, Solid, and Surprisingly Versatile
If you spend time outdoors, eat in your vehicle, or simply need leak-proof lunch kit that won’t betray you at the worst possible moment, the SIGG Gemstone Food Jar and Food Box are cracking bits of gear.
They’re tough, look smart, genuinely useful in both the wild and the workplace, and carry the kind of reliability SIGG is famous for. Whether you’re scoffing chilli on a windswept hilltop or unwrapping your lunch during a Teams meeting you didn’t want to attend, these containers have your back.
Rock-solid lunch storage — literally and figuratively.
