Light, Warm and Durable are three things that don't really go together well.

I'd steer you toward a down jacket, as it's more durable than a synthetic fill and still light and compressible for traveling. The key durability factor will be the outer shell, so nothing too lightweight like a ghost whisperer.

How about a Mont-Bell Upland Parka? Or maybe a classic Marmot Guides Down Hooded Jacket? If you want synthetic, maybe a Rab Nebula Pro.
