I recently purchased a Coleman 5 day cooler for $45.00 that was in my price range at the time but as I'm finding out should be labeled a 1 day cooler when the ambient air temps are 90+. I have guide friends that swear that the Yeti coolers are the best coolers ever and can hold ice for a week or more during the summer months. Since I plan on being in some remote areas soon for extended stays, I need to count on ice lasting longer than one day. Any advice? Any coolers that are much less than $300.00 that work just as effectively? Anyone own Yeti coolers that would not rate them as the best cooler on the market? Thanks in advance.
