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. However, the warmer weather means our packed lunches and picnics are likely to be suffering from the heat too and a kid's lunchbox just won't cut it.
The best cooler bags will keep your food and beverages cold in two ways. Either, with ice to bring the temperature down or with insulation to keep the temperature down. Cooler bags or cool boxes are a simple solution to safely store food at a colder temperature. Plus they're excellent for a picnic, barbecue or day trip.
There are plenty of options available in the UK from electric cool boxes that can be plugged into your car or cooler bag backpacks for when you’re exploring on an adventure.
Editor's pick:
• Best cooler bag overall: TOURITCoolerBackpack
• Best cooler bag backpack: Isothermal Backpack 20L
• Best car-powered cooler bag: Halfords 12V Electric Cool Box
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.
The best cooler bags
Best cooler bag overall

Review: "Love it so far. Just got it 3 days ago so that I can take the 4 and 2-year-old to the beach by myself and it has already made my life so much easier. Went to the beach today with the kids again-lugging my chair, their tent and beach toys. Putting the weight of the heaviest items on my back made the trek through the sand so much more bearable. Albeit I did not load it up with cans. 4 bottles of water. A few cut fruit jars. Dry snacks. Perfect for one adult and 2 kids."

What to look for in a cooler bag
Weight: If you're planning on travelling with your cool bag, you'll want a lightweight option. But if you plan to just use it in the garden, you'll be fine to opt for a weightier option.
Capacity: Think about the size of your family and how many people you'll need to cater for. While most bags won't specify how many people it is good for, you can work it out by litres. 18 litres can carry between 25-28 cans while 30 will usually fit around 50 cans.
Durability: Given that you're probably going to be using it for a few years, you want to make sure that your cooler bag or box of choice will support the weight of its contents and has sturdy handles or straps.
Bag or box: While a cool box is usually a bit sturdier, a cool bag is a lot easier to transport as it can be worn either over the shoulder or on your back if in the style of a backpack.
Waterproof: A must for any cooler bag, especially if taken out and about, check the lining is also leakproof.
