Boot Insulation... Who's In The Know? - 03/08/09
In cold, how does Gore's "Duratherm" compare to Primaloft 200 gram light with a Goretiex liner vs. 400 Gram Thinsulate with a Goretex liner?
Or, is Gore's Duratherm just their proprietary version that uses either Primaloft of Thinsulate?
I'm confused
