YETI’s insulated coolers are built like a tank and keep the stuff inside of them cold for eons. They are also prohibitively expensive–it’s hard to justify spending hundreds on a piece of gear that many people may only use a few times every year. Happily, YouTuber Steve Wallis figured out how to make a cooler for under $100 that has similar cooling properties. if you’ve got the time, don’t mind getting a bit dirty and would rather spend your cash on steaks than a container to keep said meat chilled, step right up and press play.
