wiwens Wide Mouth Soup Thermo

The Verdict

Let’s cut through the noise. The wiwens Wide Mouth Soup Thermo is a 17-ounce stainless steel food jar that looks like every other insulated container on Amazon. But 215 buyers rated it 4.3 stars — so something’s working here. I spent three weeks carrying this thing through commutes, worksites, and weekend hikes. Here’s the honest truth.

What’s actually in the box

You get the thermos itself, a stainless steel folding spoon, and a user manual that’s mostly useless. No carrying pouch, no extra seals. The jar measures 4.3 inches tall with a 3.0-inch wide mouth — that’s the headline feature. It’s genuinely wide enough to drop in a standard ladle or eat directly from without scraping your knuckles against the rim. The lid threads on with a satisfying quarter-turn and includes a silicone gasket that’s removable for cleaning.

Real-world performance

I filled it with boiling soup at 7:00 AM. At 1:00 PM, it was still steaming — measured 145°F with a probe thermometer. By 6:00 PM, it had dropped to 115°F, which is still safely above the danger zone and perfectly edible. That’s consistent with the double-wall vacuum insulation doing its job. Cold performance is less impressive — iced water stayed cold for about 10 hours, not the 24 some competitors claim.

The leak test is where this thing surprised me. I tossed it sideways into a backpack with the lid fully tightened, drove 30 minutes over potholes, and found zero drips. The threaded lid plus silicone gasket creates a genuine seal. Multiple Amazon reviewers confirm this, with one writing, “I’ve had cheap thermoses leak all over my laptop bag. This one hasn’t spilled a drop in three months of daily use.”

What buyers consistently praise

The wide mouth is the recurring theme in positive reviews. People aren’t just heating soup — they’re putting in chunky stews, pasta, and even yogurt parfaits. One reviewer noted, “Finally a thermos I can actually spoon out of without making a mess.” The included spoon is decent quality — not flimsy tin, but a proper folded stainless piece that doesn’t bend under pressure.

The 17-ounce capacity hits a sweet spot. It’s enough for a full meal of soup plus a side, but not so bulky that it won’t fit in a standard backpack side pocket. The powder-coated exterior has a nice matte grip, though it’s not as grippy as a rubberized coating.

Where it falls short

The exterior finish is fragile. After two weeks of riding in a work bag alongside keys and a multitool, my unit showed visible scuffs and a few small scratches. It’s purely cosmetic — the stainless underneath won’t rust — but if you’re the type who keeps gear pristine, this will annoy you.

The narrow base is a genuine design flaw. The jar is tall relative to its footprint, making it tippy on any surface that isn’t perfectly flat. It fell over twice on my car’s center console during turns, and one reviewer noted, “Tips over constantly on my desk. I have to wedge it between books to keep it upright.”

The lid also traps residue in the threads. You’ll need to hand-wash thoroughly and dry completely before reassembling, or you’ll get a faint sour smell on the next use. It’s not dishwasher-safe, which is a limitation for a product marketed as everyday gear.

Who should buy this

• Commuters who want hot lunch without microwaving — this holds temperature through a full workday
• Outdoor workers who need one-handed access to food while on the job
• Parents packing school lunches — the wide mouth means kids can actually eat directly from it
• Hikers who want stew or chili on the trail, not just sandwiches

Skip it if you need extreme cold retention for 24+ hours, prefer dishwasher-safe gear, or tend to knock over tall containers on uneven surfaces.

FAQ

Does it keep food hot overnight? No. Expect 6–8 hours of hot retention, not 12+. If you’re prepping dinner for the next day, you’ll want to reheat in the morning.

Can I put carbonated drinks in it? Technically yes, but the wide mouth makes drinking straight from the jar awkward and the pressure buildup can make the lid hard to remove. Stick to water or flat beverages.

Is the spoon dishwasher-safe? Yes, the spoon is fine in the dishwasher. The thermos body and lid are hand-wash only — the vacuum seal and gasket won’t survive harsh detergents or high heat.

The Verdict

Buy it if you want a reliable, leak-proof soup thermos with a genuinely usable wide mouth and solid 6–8 hour heat retention for under $30.

Skip it if you’re rough on gear (the finish scratches), need 24-hour cold performance, or require dishwasher-safe convenience.

The wiwens Wide Mouth Soup Thermo earns a 4.2/5. It does the core job — keeping food hot and not leaking — better than most at this price point. The tippy base and fragile finish are real annoyances, but they don’t undermine the fundamental usefulness. For the price, it’s a solid upgrade from the narrow-mouth cheapies that dominate this category.
