http://thesweethome.com/reviews/best-soft-cooler/One more that boaters use
https://www.aocoolers.com/I have bought many over the years & I never have been happy with any. As a boater I wanted one that would last a weekend & I did not need it to be bear proof. I have never found one that lasts that long.
Now that being said I have not bought any in the last five years (still recovering)*** except a $12.00 one this year that lasted 6 hours. It was for my family for a beach day.
Lasted six hours.
My therapist says it is time to buy a new one
I am in a market for one also for my little air boat if I ever get it in the water. So let is know what you get? In the mean time I will check the fall boat shows for what is new on the market.
I still feel the best cooler for value IMO is a hard cooler the Coleman six day cooler I have used it for tailgating, work parties & it has held up very well but I take care of it. It is a great cooler even if you can't throw it off a mountain or let a bear play with it. but again it is a hard cooler.
The problem with soft sided coolers is they smell, leak, fall over & don't keep things cold for long enough. Plus, they are not easy to empty the melted water when things are still in them.
