What customers say
Customers overwhelmingly praise the ThermoFlask 20 oz Food Jar for its exceptional thermal performance and outstanding value, especially as a 2 pack. Users confirm the insulation reliably keeps meals hot for a full workday. The 20-ounce capacity is considered ideal for substantial lunches. The wide mouth design enhances convenience for both filling with chunky foods and subsequent cleaning. Reviewers appreciate the robust construction that handles daily use well.

Despite minor lid concerns, the jar is viewed as a high performing, essential accessory delivering superior utility.
