I have to chime in about the Aerocoast pro cooler 2. It's the only bag that fills the niche of cooler/EFB but the quality and customer service is horrible. Holes were developing in the bottom of the EFB pocket after a couple of months. The customer service rep's response was snide and told me to learn how to use a J-Hook. Then just last week the plastic handle broke. It says it's crew tested, but I find that hard to believe. I've flown with others who have the same issues. Look at the reviews on Amazon, people complain about the same stuff.
It's unfortunate that this is the "best" bag in the segment. Because of their terrible customer service and shoddy product I'd have to say steer way clear of Aerocoast.
