S'well Stainless Steel Food Bowl 21.5 oz - Insulated Meal Container

In this review of the S'well Stainless Steel Bowls 21.5 oz, the bottom line is simple: this is a well-made insulated meal container for people who need reliable temperature retention and a neat, condensation-free exterior when transporting lunches. The package includes an insulated exterior bowl and a clear Tritan inner prep bowl, and the main selling point is the triple-layered insulation that aims to keep foods cold for up to 11 hours and hot for up to 7. It is best suited to commuters, office workers, and anyone who packs a lunch and wants a leakproof, attractive container that is built to last.

Key Features

• Triple-layered insulation: The vacuum-insulated exterior bowl is designed to keep food cold for 11 hours and hot for 7, reducing the need for ice packs or reheating in many lunch situations.
• Two-piece system: Includes an 18/8 stainless steel outer bowl and a durable Tritan inner prep bowl that nests inside for portioning and prep.
• Measured prep bowl: The inner Tritan bowl is marked with convenient measurements to make meal prep and portion control straightforward.
• Condensation-free exterior: The outer bowl stays dry to the touch and the lid is leakproof, making it easier to carry in bags without worrying about moisture or spills.
• Safe materials: The exterior is food-grade 18/8 stainless steel and the product is BPA/BPS-free and Prop 65 compliant for peace of mind.
• Easy care: Both bowls are dishwasher safe and the inner prep bowl is refrigerator, freezer and microwave-safe for flexible use.

Who It's For

The S'well 21.5 oz bowl is ideal for people who bring prepared lunches to work or school and want a durable, stylish container that performs well at maintaining temperature. It fits two cups of food in the outer bowl and 1.25 cups in the inner prep bowl, making it useful for salads, grain bowls, soups, and mixed meals when packing a main and a smaller side.

Those who should look elsewhere include people who need very large single-serving capacity or who prefer a single large plastic bowl without an inner insert. Also, a few users find the inner Tritan bowl smaller than expected, so if you regularly pack oversized portions, consider a larger insulated container.
