Winter Tights

[mudmucker]

I run down to 5 degrees. I just use a cheap $10 pair of close fitting black sweatpants over my Stabilyx tights. I buy the sweatpants a size or so smaller and find some so they fit snug and don't bag around. Great for very cold days. Might be too warm for 45 degrees but there are all sorts of thin sweatpants. At least you wouldn't be paying $100+ for something that may not work for you. I don't use the Stabilyx so much anymore. I have leg lymphedema so I use Jobst gradated compression tights for support while running - I get a gradient that is appropriate for my condition, but a person with a normal lymphatic system would choose a lower gradient. There are several brands of differing gradient schemes you could also look for that are half the cost of compression tights from some of these specialized running stores.

ETA: BYW, the Jobst comes in black
