Thanks again, Kiwi Stoker, I'll see what I can try on here but may well order, their shipping to the US isn't bad.
LPH - thanks for your input...I was thinking of checking out Endura's stuff but your experience gives me pause. I know what you mean about not worrying about the training rides, I can usually tough it out and if it looks like I'm being stupid (hypothermia is real!) call in a favor for a lift home. The Ride the Rockies ride that's got me shopping averages around 75 mi/120 km per day, and it's definitely a mountain ride environment, plus I'm hoping to do more overnight/weekend touring, so getting something more rain-worthy than what I have is an issue.
O2 Rainwear has expanded their line, I'll be looking at them next....
