HYDRO FLASK LIGHTWEIGHT TRAIL 24OZ £48

This is a very lightweight doublewalled vacuum flask with a neat and compact design. The wide mouth makes for easy filling and cleaning, and the silicon grab handle means it is easy to pull from the side pocket of a rucksack.

It’ll keep a brew warm in a pinch, but I’ve found it is best for keeping water ice-cold all day long.

VERDICT A vacuum flask that weighs little more than most standard water bottles, but which can keep water chilled for hours on end, meaning it’ll no doubt come hillwalking with me all summer long.
