Normally, I would have waited until the afternoon sun had warmed things a little, but my wife had movie plans w/ friends... having a kid = be flexible.
The Ride: Hardtail w/ Nokian studded tires...run tubeless w/ ~15 PSI
Here is the list from the top down:
Mountain Hardware Windstopper hat - sweat wicking and wind proof need I say more?
Pearl Izumi Balaclava - good for chincicles, wear it so each breath is exhausted over my face...keeps the nose running and the face thawed.
Stretch (generic) neck tube - just one more layer, as the balaclava is pretty thin
Under Armour Cold Gear top - best base layer I have found...I look like a really skinny Terrell Owens=)
Mountain Hardware fleece - I only wear this and cold gear if it is >20 degrees. It is 4x more windproof than cheap fleece
Mountain Hardware Windstopper jacket - This jacket makes riding in weather like this possible. Again, wind proof and sweat wicking
Pearl Izumi windproof bibs - I wouldn't buy them again but they are warm. The flaw is that the have no stretch around the knees so they really bind up (and make me work harder=)
Under Armour Cold Gear pants - same as shirt. see above
Nike bibs - low cut making it easier to pee
Mountainineering socks - wooly, thick, and big
Nike Shoes (same as I use all season) - tape up the holes in the insole. A lot of heat is lost through the sole of the shoe.
Performance Booties - cheap and fleece lined. The fleece lining really helps.
and last but probably most important...toe warmer packets taped to the top of my sock inside my shoe - would have lasted less than a lap w/o these.
The catch? The retail value of all this clothing is ~$1000. IMO, money better spent than on a nice trainer or power meter;)
My wife called me crazy for going riding. I called her crazy for going to see a horror movie: "27 Dresses". In the end, we agreed to disagree.
