Esbit's Vacuum Food Jug is a well-made insulated container that keeps your food or drink warm for hours. It features a pressure release button which prevents any hot substances spurting out when you twist the top off. Use the lid as a bowl. These insulated food jugs are built to last being made from Stainless Steel.
Esbit says:
Stainless steel double-walled Vacuum Flask. Pressure release push-button for avoiding any hot substance spitting out. The lid can be used as a bowl. With a silver-coated inner body for especially good heat preservation.
Nearly got linched for even suggesting that we stock a food flask - we are after all 'Ultralight Outdoor Gear'. However, I pointed out that if you want to carry hot food into the countryside and enjoy it hot hours later without getting a stove out, then these flasks are as light as the required technology gets!
Of course I got my way, so if you're out and about on a cold winters day and want to revisit that homemade stew from last night whilst lost in the hills, then you can with one of these from Esbit!
