"Not as big as you think" star star star star_border star_border This review is for an older version of this product Have just received my cool bag and although it looks and feels like a quality item (I have yet to try it) I was a little disappointed to note the label states the volume is “Approx 18 litres” as opposed to the 20 litres in the product description. I spent some time debating between 2 products and their relative volume difference. Had I known this is even smaller than I thought, I might have chosen differently. - 28 May 2021 support_agent A note from the team We're sorry this is smaller than expected.
