Made of sturdy stainless steel, this spacious flask is pretty much unbreakable, so you can carry it in your bag with peace of mind. The double-walled design insulates the flask, keeping cold drinks cold and hot drinks hot, while staying cool on the outside. The insulated cap doubles as a cup and fits neatly over the moulded stopper, which seals the flask when you've finished. The flask holds 1 litre (1 pints) and measures 33 x 8 cm (13" x 3"). Dishwasher safe.
