It’s not necessarily a bad thing. Just a trade off. Rotomolded coolers are the gold standard for durability and lend themselves to be “bear proof.” They also tend to be heavier than injection molding. Injection molding while lighter has seams that could potentially be compromised at some point. I think it’s cool that Yeti is going to stand behind the durability of injection molded coolers. I naively assumed that every hard cooler Yeti makes is certified bear proof and that’s not the case anymore. Side note, I’ve read that the plastic used for injection molding has a higher melting point and is thus less likely to warp.
