Charcoal Ultimate Flask (900ml), 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

This is an excellent Thermos. I’m just back from Antarctica with temps in the -20’s and -30’s. This flask kept my coffee warm, and it was great to have a drink of hot coffee on my breaks up Vinson. One thing I would change is I would go for the smaller size.

I haven't had the opportunity to keep anything cold in this Thermos yet, but I can say it definitely keeps my tea hot 24 hrs. I pre-heat it for about 10-20 mins before filling with hot tea, and it keeps it steaming hot 24 hours. It could possibly keep it hot longer, but I usually drink the last cup right at 24 hours after filling.

Great product. As described.

Use it for winter hiking and I really like it as it holds hot tea longer then any other thermoses I tried. I like very hot tea at the end of the trail. Love it

great

This is really the best I have used in a long time. Works great, keeps the water warm longer than I expected.

Best X 100

I received a unit this afternoon. When I took the instruction inside out of the thermos and shook the bottle I can hear some noise like a small piece of metal is moving up and down with the shaking motion. I’ll request a new unit in case it’s broken.

sıcak tutması ve tasarımı güzel. almaya tavsiye edirim.

Diese anthrazitfarbene Edelstahl-Thermosflasche mit Trinkbecher vereint Stil und Funktionalität auf beeindruckende Weise. Die Flasche ist nicht nur sehr leicht, sondern auch perfekt dimensioniert. Nach drei Monaten intensiver Nutzung kann ich mit Freude berichten, dass sie kein einziges Mal ausgelaufen ist. Die herausnehmbare Kappe erleichtert das Befüllen und Reinigen. Die Flasche sieht nicht nur schick aus, sondern hält auch, was sie verspricht. Selbst nach 24 Stunden bleibt mein Getränk heiß, und das ist besonders beeindruckend. Die Gummipolsterung am Boden verhindert ein Verrutschen, was sich als äußerst praktisch erwiesen hat, vor allem wenn ich die Flasche im Zug auf einem Tisch abstellen möchte. Zusätzlich sorgt das Gummiband am Korpus dafür, dass die Flasche besser in der Hand liegt. Alles in allem eine absolut empfehlenswerte Outdoor-Flasche, die meine Erwartungen übertroffen hat. Ich bin rundum zufrieden und freue mich auf viele weitere Monate der Nutzung!
