Thermos - Matt Black Ultimate Flask (500ml), Reusable Insulated Stainless Steel Thermal Coffee Cup for Hot or Cold Drinks, Vacuum Sealed Water Flask with a Leak-Proof Lid, 24hr Hot/24hr Cold

I made tea even after 24 hours, i couldn’t believe my eyes. Lightweight. Best design. I love it

Perfekt!!!

A truly outstanding little flask. I have the 900ml and the 500ml both are exceptional and keep everything very hot for 24 hours, I use the small one for soups and all sorts. Great value for money and excellent performance. Well worth buying.

Gets excellent reviews. Update: bought replacement and heat retention is truly amazing, just tested after 18 hours and water v hot, even without pre heating. Now have 2, using the other for soup and meals that can be easily get in and out. Ideal for long trips to a destination, as everything's stays really hot. Original review: Bought used in 'mint' condition. Unfortunately it was delivered severely dented, so return in progress. This seems to highlight it is made of lightweight metal and may explain why it has silicone bumpers. So lightness exchanged for being physically less robust and easily damaged! Looks like it was packed poorly and or not handled well, maybe considered a 'fragile' item

Excellent, I decided to try this flask under harse conditions, before reviewing. I use it for my hiking, during winter conditions. The flask has performed perfectly. It's light weight and keeps my brew hot!
