Trans Alaska Insulator Jacket, Item# 9IS-922874

I don't have this model but more then a few people are very pleased with it. I have the pataognia M steath down jacket and it does what i need it to but it is a higher costing piece.

This, a down vest and a lightweight wind/waterproof jacket will fit in an Alice pack pocket. I tend to replace the fleece with a lightweight wool shirt now days, as it doesn't get holes from the fire. But for hiking in wet conditions its very nice.
