I am a large. What size should I get considering I will be wearing underlayers?
Wear the jacket you normally wear, layering doesn't mean you need to bulk up. First layer has come a long way. Wearing one base layer will go a really long way, that is all you need. Thick for colder days and light for warmer days. check them out here: http://www.dogfunk.com/burton-expedition-1-4-zip-top-womens and here: http://www.dogfunk.com/burton-lightweight-crew-womens
