  This is my first big let down and not because of the product but the description of the colour, told as burnt orange, photo looks orange, but is an ugly Brown and disappointed with this.

  Great flask, very lightweight, under 400g, less than half my other 1 liter vacuum flask, it also has a Wide mouth. I have been out in winter NZ a few times with it and it has kept tea rehydrate and hot overnight. No cup attached but I don't mind that, if camping I'll have something otherwise just add some snow from a cold creek water. A mate has had one for years so longevity looks good.
