ThermoFlask 20 oz Double Wall Insulated Food Jar 2-Pack - Keeps Meals

In this review the ThermoFlask 20 oz Double Wall Insulated Food Jar 2-Pack is examined for everyday meal storage and transport. The bottom line: this pair is best for people who want reliable temperature retention and a spill-free, reusable option for lunches and on-the-go meals. The reviewer found the jars deliver consistent warmth or chill thanks to Temp-Lock Technology, and the compact 20 oz size fits a full meal for many users while eliminating single-use containers.

Key Features

• Temp-Lock Technology: Keeps food hot for up to 12 hours or cold for up to 24 hours so meals stay at serving temperature throughout the day.
• Leak-proof screw-on lid: Provides a secure seal to prevent spills in a bag or lunch box while the easy-grip handle makes carrying comfortable.
• Dishwasher friendly: The jars are safe to place in the dishwasher, which simplifies cleanup after daily use.
• Durable 18/8 stainless steel: Food-grade construction prevents flavor transfer and maintains pure taste, while the powder coat finish adds extra protection.
• Non-slip silicone base: A built-in base prevents sliding and protects surfaces, useful in kitchens, desks, or picnic tables.

Who It's For

The ThermoFlask 20 oz 2-pack is ideal for commuters, parents packing school lunches, and anyone who wants a reusable, insulated jar for soups, stews, yogurt or salads. The two-jar set covers multiple meals or sharing between adults and children, and the colors are described as vibrant in person which is a nice touch for personalizing lunch gear.

Those who need extremely heavy-duty handles or expect daily rough treatment may want to check alternatives, as a small number of customers reported handle breakage within a month. If you need very large capacity containers, larger insulated food jars would be a better fit.
