While 40 or 35 is not quite cold enough for me to be digging out my long winter leggings, you have reminded me that I need to GET some long winter leggings again this year.

Both pairs of mine that I had been running in for the past 3 years finally gave it up at the end of the winter season last year and the seam on the right leg ripped in the inner thigh area on both (I always manage to wear through the inner thigh on the right leg, I must do something differently with that leg than the other). As a fluffier runner, I can be hard on the inner thighs of pants.

3 years is a pretty good run, though... no pun intended.
I had a pair of Sugoi Mid-Zero tights for like the 25-30F range and Sub-Zero ones for 25F and below. They weren't quite adequate when you got down into the single digits but they were thicker than the Mid-Zeros at least.

Hopefully the current models will fit me ok. I seem to have located about 20 lbs since I originally bought them, although only a few of those are since the last time I wore them, so fingers crossed... or I guess I better buckle down and lose a couple lbs before winter so I can run outside in winter again.

I haven't made it back outside to run again since August, but my running group is starting back up the free winter group probably around Thanksgiving, so I'll be joining them for that again at least.
