If you are looking for the toughest flask for all of your adventures then look no further!
The Stanley Master Series 750ml Vacuum Bottle is the most sturdy, hard wearing flask on the market. In fact, it is unbreakable. Guaranteed!
This incredible flask is constructed from 1.0mm 18/8 stainless steel that is both rust proof and naturally BPA free. QuadVac™ technology adds a double layer barrier to double wall vacuum insulation for four layers of protection from convective, conductive and radiant energy transfer. QuadVac™ locks in heat or cold like no other meaning that contents stay hot or cold for a massive 27 hours and iced for an unbelievable 100 hours!
The lid is also a vacuum insulated 18/8 stainless steel cup which keeps drinks hot for 20 minutes. There is a rubber pad to the bottom of the cup to help prevent any slips and the stopper is steel lined to prevent any plastic contact with the contents.
The hardened outer finish not only looks great but adds another layer of protection to this incredible flask. If that is not enough, the whole item is dishwasher safe and protected by the Stanley Lifetime Warranty.
