THERMOS FUNTAINER 16 Ounce Stainless Steel Vacuum Bottle - Keeps

In this review of the THERMOS FUNTAINER 16 ounce bottle, the bottom line is clear: it is a practical, durable insulated bottle that keeps drinks cold for a full day and stands up to kid-level use. The pack of six matte black bottles is aimed at families, caregivers, and anyone who needs a reliable mid-size bottle for school, outings, or commuting. The single biggest reason to buy is the vacuum insulation that keeps beverages cold for up to 12 hours while the 18/8 stainless steel construction tolerates everyday drops and bangs.

Key Features

• Vacuum insulation: Keeps drinks cold for up to 12 hours so cold beverages remain refreshing throughout the day.
• Durable stainless steel: 18/8 stainless steel construction resists dings and wear, making the bottle suitable for daily use and rough handling.
• Wide spout lid: The wide spout and push button lid make drinking and refilling easy while limiting contact with the spout thanks to the covered design.
• Kid-friendly carry: Integrated carry handle with a soft touch grip and a lightweight, compact profile that is easy for small hands to manage.
• Easy to clean: The bottle disassembles to two main parts for straightforward cleaning and is dishwasher safe, though hand washing is recommended.
• Multi-pack convenience: Sold as a pack of six in black matte, which helps families or groups outfit multiple users at once.

Who It's For

This bottle is best for parents packing lunches, coaches and group leaders who need multiple identical bottles, or individuals who want a robust 16 ounce insulated container for cold drinks. Its size is large enough for a substantial drink but still compact for lunchboxes and backpack side pockets.

Those who routinely carry hot beverages should look elsewhere, as the design and description advise this model is not for hot liquids. Also, if you need a completely leakproof screw-top for packing in a bag that will be tipped frequently, consider alternative lids designed specifically for leakproof transport.
