Swig Food Jar

While performance can vary based on the starting temperature of your food and how often you open the lid, the vacuum-insulated walls are designed to maintain temperature for several hours. For best results, we recommend pre-heating the jar with boiling water for hot foods or chilling it with ice water for cold items before packing.

The 12 oz size is best suited for snacks, sides, or smaller portions like a cup of soup, yogurt, or fruit salad. It is generally too small for a hearty, main-course lunch, but it is perfect for keeping smaller items at the right temperature throughout the day.

While the stainless steel construction is durable, we recommend hand-washing the jar to preserve the integrity of the vacuum seal and the exterior finish. Harsh dishwasher detergents and high heat cycles can degrade the insulation performance over time.

Yes, the lid is designed to create a secure, airtight seal, making it safe to toss in a bag without worrying about spills. Just ensure the lid is screwed on tightly and evenly before you head out.

No, high-quality stainless steel is non-reactive and does not retain flavors or odors from previous meals. As long as you wash it thoroughly between uses, your food will taste exactly as it should.
