army flask carrier?

[DanDan The man called Dan]

I've just bought one of these online with the intetion of carrying a thermos when I 'm out walking but don't want to take a bag.

I've never seen one in the flesh, anyone out there familiar with them and can tell me the biggest or best type of thermal flask that will fit?

Thanks

Army Arctic issue flask case really good bit of kit originally designed for the old glass thermos to stop them breaking. The standard one pint will fit, but steel flasks have got slimmer and as such you should try a few to get one to fit. Still a handy bit of kit, used one for years.
