These are far classier than hard plastic ‘Esky’ type coolers. They are made from 600 denier polyester which looks like a high quality canvas but does not rot or mildew like canvas. This 20L unit is good for larger amount of drinks and works well with ice bricks but is ok with actual ice. There is a nifty feature on the top lid flap - 2 x Hook-and-Loop 120mm square doors. These give you access to standing up pre-packed bottles. You simply open the flap and pull the bottle out by the neck. No more digging around in slushy ice! It also has a separate zipped side bag for other items such as picnic plates, napkins, etc. This a is VERY stylish drinks cooler!
