Sealey 25ltr Rucksack Cool Bag
Best price: £41.28 | Size: 25 litres
It might seem a little off the wall, but this soft backpack coolbox works well, particularly if you need to carry your food and drink. It’s comfortable to wear with lots of flexible storage, including for big bottles. There’s a rip-open hatch to access contents to minimise temperature loss, and it quickly got down to 12 deg C below ambient. Keen price makes this a great alternative.
