10 Best Hot Soup Thermos 2025 in the United States

The Pawtong 12oz Insulated Vacuum Food Jar is a compact and practical choice for keeping soup or hot food warm for about 5 hours, thanks to its vacuum-sealed double-wall stainless steel design. Its 12-ounce capacity is a nice upgrade for kids, offering enough portion size for meals without being bulky. The stainless steel construction is durable and food-safe, with a wide mouth that makes it easy to fill and clean.

A standout feature is the buckle lid with a press-seal and a handle that kids can easily open, which also ensures the jar is 100% leakproof—giving peace of mind when carrying it in bags. The lid’s silicone gasket adds to the spill protection. However, this thermos is not microwave-safe, so reheating needs to be done separately. While it is labeled dishwasher safe, users should carefully follow the instructions, especially when removing and reassembling the lid to maintain the seal.

Weighing just over 11 ounces and with a small size, it’s quite portable and suitable for school, work, or outdoor use. If you want a simple, kid-friendly insulated jar that balances ease of use, good insulation, and spill protection, this Pawtong model is a solid pick. Just remember to preheat or precool it before use for best temperature retention.

The THERMOS Stainless King Vacuum-Insulated Food Jar is an excellent choice for anyone in need of a reliable container for hot or cold meals, particularly soups. Its standout feature is the vacuum insulation technology, which keeps soups hot for up to 9 hours and cold foods chilled for up to 14 hours, making it great for daily lunch or outdoor adventures. The durable 18/8 stainless steel construction ensures that it can withstand everyday use, and the exterior remains sweat-proof, meaning it won't leave moisture on your hands or surfaces. Plus, the included foldable spoon is convenient for on-the-go dining and can be stored easily in the lid, which doubles as a serving bowl.

Capacity-wise, the 16-ounce size is suitable for a hearty serving of soup, but those who need larger portions can opt for the 24-ounce or 47-ounce options. Cleaning is simple as it is dishwasher safe, although it's recommended to place it on the top rack. This ease of cleaning adds to its appeal for busy users.

On the downside, while the jar is designed for solid performance, it’s not microwave or oven safe, limiting its versatility when it comes to reheating food. Additionally, at 4.8 ounces, while it’s lightweight, it might still feel a bit bulky for some users seeking ultra-portability. The THERMOS Stainless King Food Jar is a robust choice for soup lovers and those needing a dependable thermos for various meals, with a few limitations in heating options and bulkiness to consider.

The Hydro Flask Food Jar is a solid choice if you're looking for a reliable container to keep your soups or meals hot or cold for several hours. Its double-wall vacuum insulation, branded as TempShield, does a good job maintaining temperature, so your hot soup stays warm and cold items stay chilled for a decent stretch of time. The 20-ounce capacity is a practical size—not too big or small—perfect for a lunch portion or snacks on the go. Made from durable stainless steel, it ensures your food tastes fresh without any leftover flavors from previous meals.

The lid is designed with a soft grip that seals tightly and is leakproof, making it convenient and safe to toss into your bag without worrying about spills. However, while the lid is easy to open and close, the jar’s cylindrical shape and stainless steel material might make it a bit heavier than plastic alternatives, which could be a consideration if you're prioritizing ultra-lightweight gear. Though dishwasher safe claims are mentioned in some features, the care instructions specify hand washing only, so cleaning might require a bit more effort to maintain the jar’s finish and insulation quality.

The compact size and leakproof design make it quite portable for daily use, hiking, or travel. This food jar is well suited for people who want a sturdy, temperature-retentive container and don't mind a bit of extra weight or hand washing to keep it in good shape.
