This morning was the coldest day of the winter yet that I've ridden, at 19 degreesF. (There was a super cold day two weeks ago, but I was still hacking up pieces of lung back then).
I prepared for the cold ride with Falke wool sweater leggings, thick smartwool hiking socks, a thin ibex undershirt (long sleeve) a cotton jersey dress and a pair of knee high leather boots.
Over that I wore my Nau trench coat, my normal helmet, "ear pods" earwarmers, a scarf wrapped around my lower face and throat and a pair of "ski gloves" with liner gloves.
My toes were a bit cold- wish I'd worn two pairs of socks, or foot warmers, but other than that everything was perfectly warm.
Unfortunately I can't say the same for my coffee- I must have spilled a bit, and it froze before it could run all the way down the side of the mug.
The coffee inside was reasonably warm, but I still put it in a normal mug and re-warmed it in the microwave.
