## Long description

Hydro Flask 12 oz (355 ml) Food Jar RF12374 stainless steel vacuum insulated is a compact food thermos designed to retain temperature for meals and snacks. The 355 ml capacity suits single servings of soup, stew, porridge or chilled salads. Constructed from double-wall stainless steel with vacuum insulation, it is intended to keep contents hot or cold for extended periods while resisting condensation on the exterior. The wide-mouth opening allows straightforward filling, eating directly from the jar and easier cleaning.
Advantages
The stainless steel vacuum construction provides reliable thermal retention for hot and cold foods without imparting flavours. The compact 355 ml volume balances portability and portion size for daily use. A wide-mouth design simplifies loading, serving and cleaning, and the durable exterior resists dents and everyday wear. Compatible with wide-mouth lids and accessories, the jar integrates with common hydration and food-storage solutions.
Suitable for
Taking hot soups, stews or porridge to work or school
Packing chilled salads, yogurts or fruit for picnics and travel
Outdoor activities where compact, insulated food storage is needed
Meal prep when single-serving temperature retention is required
When it may not be suitable
The 355 ml capacity is intended for single portions and may be insufficient for larger meals or multi-person use. It is not designed for long-term storage of perishable foods beyond recommended safe refrigeration times and is not a replacement for insulated containers with refrigeration or heating functions.
Key specifications
Capacity: 355 ml (12 oz)
Material: stainless steel, double-wall construction
Insulation: vacuum insulated
Opening: wide-mouth for easy filling and cleaning
Use: suitable for hot and cold foods; condensation-resistant exterior
How to use
Preheat or precool the jar by filling it with hot or cold water for a few minutes and then emptying before adding your meal to improve temperature retention. Fill the jar leaving a small headspace to avoid spills, secure the lid tightly and carry upright. For eating directly from the jar, use suitable utensils through the wide mouth. After use, wash by hand with warm, soapy water or follow any manufacturer cleaning instructions; allow to dry fully before storing.
What to consider before purchase
Confirm that a 355 ml capacity meets your portion needs
Check compatibility with wide-mouth lids or accessories you plan to use
Consider whether a non-insulated or larger container would better suit multi-person meals
Usage recommendations
For best results, preheat or precool the jar and avoid frequent lid opening to maintain temperature. Hand washing and thorough drying will prolong the life of the stainless steel finish and the vacuum seal.
