They brought in the services of the guy, Eddie Bauer, and the man, L.L.

Bean, like Leon Leon Wood Bean.

There were multiple Chaunceys.

Yes.

He's got these like wires sticking out of his body.

You can find these old pictures of like Chauncey in the cold lab being like observed by men with clipboards, you know, and like Chauncey's wearing a jacket.

And so they come up with this incredible thing called layering.

This game-changing jacket and jacket system is called the M43.

M stands for model, 43 because it was made in 1943.

It's got four pockets, two at the chest, two at the hip.
