So I'm heading out tomorrow and the temperature for the hiking part of Saturday and Sunday could be in the 40s, but with the potential to drop into the 30s, or even up to the low 50s at low elevation. I have lovely down to keep me warm when stopped but this temperature for moving confuses me a bit. In the winter, I tend to get up before dawn and hike in the coldest hours of the day.
Option One – My normal for Winter: My Icebreaker GT 200 long-sleeve baselayer AND Capilene 4 to throw on in the mornings or when it is cold while moving (plus Montane Spekt eVent shell to layer for wind/elemental protection).
Option Two: Icebreaker GT 200 AND North Face Windstopper fleece vest for the "I'm cold but moving" choice (plus Montane Spekt eVent shell to layer for wind/elemental protection).
I've never taken the vest out before, thinking it not worth the weight. But I can't fight a thought that I'll wear it the entire time and not overheat in it the same way I'm guaranteed to in the Cap 4. (And I'm worried that a lighter midweight or just the baselayer and shell won't add the extra heat I might need while hiking in the morning).
