Saw your Dragon post, in gear.
The Dragon uses the same Hydratex liner as many of the other REV'IT! products. The only reason REV'IT doesn't use Gore-Tex is because BMW gear currently has the Gore-Tex license for motorcycle clothing.
The Dragon has been very well received so far, especially with the Hi-Vis colorway. Think of it as an more economical Cayenne without some of the bells and whistles.
The windproof / waterproof / breathable qualities on the Dragon are on par with any of the other higher end REV'IT! gear. I am sure if anyone else shot you a line they would echo my thoughts.
Let me know if you would like me to dive deeper into how the membrane actually works its "magic"
Rest assured it won't leak, though.
