I'll be headed up to Alaska (BC, Yukon, Fairbanks, Anchorage, Valdez) end of June and most of July. Not doing Dempster or the Artic Circle.) Can't decide on which gear to take: Option 1: Olympia Airglides (with the wp liners) and Gerbings for cold spells, and bring rain gear, or Option 2: FirstGear Kilimanjaro Jacket and Pants and bring rain gear for the extreme weather. I'm leaning to the Olympia for greater comfort range if it gets warm. Any suggestions (other than buying new gear).
