YETI coolers are built using the same roto-molded polyethylene material as whitewater kayaks. So theoretically, you could ride them down the rapids. We don't recommend that, though. They're much better for keeping your food and drinks ice cold, and keeping the bears out. YETI coolers are grizzly-proof. Yeah, you heard us. Don't believe it? Watch a grizzly try:
If a grizzly can't dent a YETI cooler, you probably can't either. But this is a crazy world, and sometimes the impossible happens. That's why YETI is backed by a 5-year warranty; just in case the grizzly gets lucky next time.
