HYDRO FLASK 20OZ INSULATED FOOD JAR £40

What’s better than a limp, soggy sandwich at lunch? Almost anything but certainly something hot. The Hydro Flask food jar has double-wall vacuum insulation to keep food hot or cold for hours with a wide mouth and leakproof, rubberised lid that’s easy to open even with cold fingers.

Just don’t forget your spork.

VERDICT A bombproof, leakproof little food jar for hot meals on a hilltop.
