Staying hydrated when doing any physical activity is paramount to being healthy. Whether you’re on a two hour romp around your local woodland, or on a full-blown expedition, the importance of ensuring you get enough fluid cannot be stressed enough.

Obviously, a reusable drinks container is the way to go, what with single-use plastic containers being problematic for the environment. However, that slightly rusty, tartan flask your nan gave you a few years ago isn’t going to cut the mustard in the great outdoors.

If you want a super durable flask that’s going to survive everything you can throw at it, then the Stanley Master Series 1.3l Vacuum Bottle is for you. Simply put, it’s an absolute work-horse.

“It has trademarked QuadVac insulation, meaning it will keep its contents hot for up to 40 hours. That’s almost two days.”

It’s made from 1.0mm thick stainless steel, so it can withstand impacts while you’re outdoors. Furthermore, it’s rust proof, and naturally BPA-free. Not sure why that’s important? BPA is an industrial chemical used since the 1960’s to coat the inside of metal food and drink containers, but studies show this chemical can seep into food and be harmful. There are no such worries with the Stanley Master Series Bottle.

With the robustness assured, what’s the next question on anybody’s lips when looking at a flask? Will it keep the hot things hot, and the cold things cold? Stanley aren’t going to let you down here. It has trademarked QuadVac insulation, meaning it will keep its contents hot for up to 40 hours. That’s almost two days!

As such, even when you’re not on an outdoor adventure, you can make your morning coffee the night before knowing it’ll still be piping hot the next morning. You’ve just bagged yourself another five minutes in bed.
