I have been wearing JR Alter-Ego for about 18mths now and love it. BUT.
Don't you love a BUT. Its warm if it has the waterproof liner in it. But if it rains and is warm you feel like being in a sauna. I rode a big ride couple weekends ago with it on with snow at Uralla and Armidale ( story here

I am going to the new JR Balistic 7 gear.
