Going on my first sheep hunt this August in the Chugach and looking for packable lightweight raingear. I have read some good about HH Impertech but they do not seem to be lightweight and a little on the bulky side. I no longer wear "breathable" waterproof hunt clothing because I sweat faster that it breathes. I am also considering Sporthill Expedition pants/jacket ( Barneys of course) with Patagonia Capilene 2 or 3 as a base layer. Any thoughts?
