The weather here in the North end of the Willamette Valley is pretty mild most of the time. I don't usually have much of a problem with cold as long as I'm active. If I'm setting still outdoors, like for a sporting event, I use a lap robe. If I'm active then my kilt with wool kilt hose (and proper upper body clothing of course) is enough to keep me warm. I suppose wearing an "underkilt" might make sense, but I'm suprised that the Sport Kilt adds that much comfort. The Sport Kilt that I have is made of such light material that I only use it around the house as an alternative to a bath wrap. Are your SK's heavier than mine Robert? Which UK's do you have? I wore my Olive Neotraditional UK and kilt hose to hike around town during our snow storm last winter (for those of you from other areas our definition of "snow storm" is 3" and about 30 degrees).
