I am planning a long winter trek and was hoping for some quick feedback about my system. I am relatively new to alpine hiking. Temperatures should range from mid-30's to low teens while active and some 0 degree nights.
Base - Midweight LS Merino 1/4 Zip (Gucci M3)
Mid - R1 (not purchased) or deadbird Atom LT (already own for 3 season insulation)
"Winter" Windshirt - Rab Alpine Pullover
Puffy - FF Helios Hoody (camp/stops)
Base - Light Cap
Pant - Marmot Scree Softshell
What do you think? My big question is about the midlayer. I have read so much great stuff about the R1, especially as a base/mid under the windshirt. I love the Atom LT for climbing, but fear I would overheat on the move with the ATom LT over the baselayer even in the coldest conditions, and the R1 would give me more versatility. Of course being the cheap-A$$ I am, if the Atom works, I could save the cash on the R1.
So, should I ditch the Atom for an R1 or equivalent?
Thanks for any help, I know its probably a stupid question..
