Here's the perfect travel thermos flask. Double wall insulated with stainless steel interior and exterior (satin finish). Has a comfortable retractable handle and also and adjustable shoulder strap.

This Thermos bottle is made of unbreakable 18/8 stainless steel. The TherMax double wall vacuum insulation locks in temperature to preserve flavor and freshness. It virtually eliminates temperature change by creating an airless vacuum space between the two stainless steel walls. The result is an insulation layer that performs better than any other.

A superior insulated container you can depend on to keep your beverages and food hotter, colder, fresher, longer. Bottle stays cool to the touch with hot liquids and is condensation-free with cold. The pouring lid opens with push button ease and locks closed for leak-proof travel. With the lid off, this model has a wide mouth opening (3" diameter) that makes filling and cleaning easy. It's great for food as well as coffee.

This high quality flask has a 12/24 hour thermal rating. Hot/Cold.

I tested it for hot liquids; my test started with 200 degree water, and was 183 degrees after 6 hours and still 168 degrees after 12 hours. WOW, what thermal retention!

Capacity is 48 oz., 1.4 liter. This thermal flask stands 10 1/4" tall, with a 4 1/2” base diameter, and is topped off with 2 serving cups. There is an inner one that is hard plastic and is more like a bowl for soups and stews, and the outer one that is the top that screws on and is for liquids.

It comes with a lifetime warranty from Thermos. Model FDH1405P
