The original poster asked about the Pop's coat. After 6 pages of opinions about leather vs flasher vs pea coat vs dress wool, his question is still unanswered.

Pops is the best. Get the calf skin. It looks much better than the goat. Much finer grain, softer. Get fitted for the coat. Pops will ask for a whole lot of measurements, not just give you a "44 regular".

Is it worth it? Your call. My company gives the Pops coat free to new hires. After wearing it for a few years it still looks new and is very warm. If you go to Canada you may want the liner. If not the main coat is plenty warm enough. I guess I would have bought it anyway if it wasn't provided.

At my last company we had to buy the Gibson and Barnes goat skin coat. It was OK but never fit well or allowed free movement. It is like comparing a Mercedes to a Chevy.
