It is likely to become more difficult to find YETI knock-offs/clones/whatever as YETI has sued various companies for infringement. Walmart's Ozark Trail line was stopped, I heard RTIC lost their trial and another company shut down saying it wasn't worth it.RTIC tumblers, identical and a fraction of Yeti's cost.. i have both, no difference (xcpt the lid, they look different but they're interchangeable)
Also, I've read that there are YETI fakes out there that look quite similar and the main differences are printing errors in the papers and a sightly different lid font, but otherwise quite similar in appearance. If you are buying online, try to buy from reputable sources.
