I'm looking for layering recommendations to ride(commute) at night at 30 to 20 degrees underneath this: http://images.zyro.co.uk/ImageGen.as...s/_noimage.png

I'm trying to reduce my apparel bulk in this temp range. I already have on order from their outlet store the Assos skinfoil for winter and winter+. Now i'm $210 lighter in the wallet. I'm thinking about going with Gore Windstopper base layer, either ss or vest as the next to skin layer and skinfoil(winter or winter+ depending on temp) as a mid layer. FYI I went one size up on Altura NV peloton Jersey(both colors). I went with my regular size on the skinfoil since they're somewhat 'stretchy'. And I'd go a size up on the Gore WS if I go this route.

Do you have any other recommendations on a next to skin baselayer? The only requirements is that it has to be thin and windproof. Oh...I will be riding at full speed hence the reason for the windproof baselayer and definitely want the Altura jersey as the top layer, so gilets or other outer garments are verboden. ...unless it's below the above mentioned temp.
