# Polar Gear 400ml Insulated Food Flask with Spoon

Polar Gear’s 400ml insulated food flask is a compact stainless-steel container for soup and other packed meals, with a spoon held by a silicone band.

## At a glance

- 400ml capacity for a single modest portion of soup, porridge or another packed meal.
- The maker claims hot or cold contents can be kept at temperature for up to six hours, with preheating or precooling required.
- Wide opening supports eating from the flask, and the included spoon is held by a silicone band.
- Screw-lock lid and double-wall insulation are described as leakproof and condensation resistant when the lid is properly closed.

## Pros

- Compact capacity and wide mouth make it practical for portable portions and eating directly from the container.
- The spoon is carried on the flask, reducing the need to pack separate cutlery.
- Stainless-steel construction and a claimed six-hour hot or cold retention window support packed meals away from home.

## Cons

- Hand washing is required, so it is less convenient than a dishwasher-safe food container.
- At 400ml, it may be too small for buyers who want a larger meal portion.

## Customer feedback

Customer feedback highlights meals staying hot, the compact size and wide opening, ease of cleaning, and usefulness for school lunches. These reported benefits fit the flask’s 400ml capacity and wide-neck design, while the maker’s six-hour retention claim remains a listing claim rather than a customer guarantee. Durability feedback is mixed, including reports of a lid breaking within three weeks, so buyers who prioritise long-term lid reliability should weigh that concern.
- Positive themes: Customers report good heat retention and find the compact size and wide opening convenient for eating.
- Positive themes: Customers appreciate ease of cleaning and usefulness for school lunches.
- Mixed feedback: Durability feedback is mixed, with some customers reporting that the lid broke within three weeks of use.
