Well I don't know you definition of "packable". Mine obviously would be a TAD Stealth or Stealth LT. Even the their fleece hoodies/jackets are pretty "wind proof" and all TAD items (even pants) are treated with "DWR" (Durable water repellant). Will it compress like the "Charles River"; probably not. Will it compress good enough? I think so. Do you want to keep $500 jacket in a bag? No, you carry it with you when you check the weather in the morning and it says that it will rain...
