35 million years ago, dinosaurs ruled the world. Back then, things were cold, and no one had even heard of the Burton Restricted Kurtz Down Jacket. Instead, to stay warm, all the dinosaurs ate each other. Dinosaur fat, similar to whale and seal blubber and the Burton Restricted Kurtz Down Jacket, has super insulating properties. In today's world filled with espresso machines, hybrid cars, and escalators, no one has time to eat whale or seal blubber, and most of the dinosaurs are gone, so all one can really do when it gets cold out is wear the Kurtz Down Jacket. Just another educational moment brought to you by Burton.
