I’m looking at the Montbell “permafrost light” down jacket vs the “alpine light” down jacket.
Specs here:
As far as I can tell, the difference is the shell material; both fill weights are listed as 4oz. The permafrost is a 30d windstopper fabric, while the alpine is 30d “ballistic” nylon. I’m not familiar with the difference, but the permafrost is $100 and 2.5 oz more.
I’d be using this in the cascades, so if the windstopper is considerably more water resistant, allowing it to be used as a belay jacket, it may be worth the extra cost and weight. Any thoughts?
