let me correct that, you dont feel the heat from them anymore at that temp, it pretty much just keeps your hands mildly uncomfortable.
Dont forget that i dont have handguards. if i did, they would work much better.
i put powermad handguards on my duc, they worked alright, btu the best thing i did was the big "polar hands." those big things taht slip over the entire bar and up your wrist. the only problem is if you have to pull your hand out. sometimes it's hard to get your hand back in quickly.
i have also found that when the temp hits the teens there is no comfortable. you jsut stay less uncomfortable depending pn your gear.
also, if you don't ever wash your bike it has a ntural protection from salt
