Review: Nice size for lunch and good insulation for what it is. - Take a lunch to work daily--purchased this one to replace one that I left somewhere on campus. I like the size of this and the ability to expand the depth if needed. The ice pack I use is typically still partially frozen when I get home, so I am satisfied with the ability to keep stuff cool, even somedays when I am doing field work and packing this around in a hot car till lunchtime. Zipper is smooth and I have had zero problems with it; the entire item is well constructed, and easy to clean the outside if needed. Would purchase again.
Review: Best Quality and Spacious - Best quality, I use it for school lunches for my son. This got be the best I have had all through his Primary and Secondary years. There’s so much space and the inside is beautiful will keep food cool for a very long time. I also love the side for the his water bottle. This is high quality, i recommend.
