Blue Coolers has just released a new lighter weight and smaller dimension cooler branded as Cobalt Coolers. These cooler have been added to reduce the weight and overall size of large rotomolded coolers but still offer superior ice retention over the cheap formed Colman coolers you used to pick up as a kid. The same manufacture procedure is used to create these highly durable coolers, plus they added a more friendly closure (which I prefer) and cut the weight. We were really excited to get to take a first look at the Cobalt Coolers and compare them with the Blue Cooler we already reviewed here as well as some of the competition from Rtic Reviews we did here.
