The best cooler bags to buy this summer

by Tiffany Wallis |

We’re hopeful that the British summer is going to bring a number of sunny days across the UK so we can get outside to socialise at the beach, BBQs, in the park and in the garden.

But the warmer weather means our packed lunches and picnics are likely to be suffering from the heat too.

The best cooler bags will keep your food and beverages cold in two ways: either with ice to bring the temperature down, and/or through insulation to keep the temperature down.

Cool boxes are a simple solution to safely store food at a colder temperature – excellent for a picnic or barbecue.

There are plenty of options available in the UK from electric cool boxes that can be plugged into your car or cool box backpacks for when you’re exploring on an adventure.

To help you choose the best cooler bag out there, we’ve compiled a list of our favourite options from a range of brands to suit all budgets.
