90 minutes today, 11 degrees and no wind at the start.

Extremities are cold first, so make sure your core is warm. Beyond that:

* Marmot snowboard gloves over REI polypropylene liners

* Quilted Gore booties over PI toe covers over shoes over thick wool hiking socks, loose shoes.

My feet got a little cold near the end when we were going downhill at 25+ for a couple of minutes. Hands were warm the entire way.

For reference, I was also wearing:

* Medium weight balaclava
* Craft thin base layer
* Medium poly base layer #2
* Fairly thick Biemme LS jersey
* Assos knickers (not Roubaix)
* Custom (Lou) Fox Wear windproof pants
* Custom (Lou) Fox Wear windproof front / Polartec rear jacket

Temperature rose to near 20 and I was overdressed. I'd probably be good to 0 F for 90 minutes in this outfit, assuming little or no wind. Below that I might go with Roubaix knickers.

Have fun -
Tim
