The temperature has dropped pretty drastically here lately, with overnight temps settling down in the single digits (Fahrenheit). Days have crept up into the 20s and even the low 30s, which means that it's time for serious business when dressing for the day. In past years, my go-to coat was a leather shearling coat that still sees some appearances on cold days, but the other evening I remembered that I'd acquired a vintage pea coat (complete with a name stamped in the lining) late last spring and had been stashing it for major thermometer drops.
The coat is incredibly heavy, and I've found that it's so warm that I only need to button the middle two buttons during the morning temps, while I drop down to one in the later part of the day (pictured).
With my usual layering, I imagine that the coat would easily suffice for sub-zero temperatures (buttoned up to the neck), as it blocks wind like no other and heats up the body quickly with a bit of walking.
I can't believe I never owned one of these before. It's definitely become an instant staple.
