I am trying to decide which upper body layering system to take on an upcoming winter trip to the BWCA in Minnesota.
Daytime temps between -5F (-20C) and 32 F (0C). Average 20F (-7C).
Skiing at a relaxed pace on lakes, short stretches of wooded, hilly, crossings from lake to lake.
Camping with hot tent, so long term moisture retention is not a problem, but of course, day time flash off is.
Baselayer: Brynje wool mesh zip neck.
Outer layer: Cioch Direct Nikwax Analogy jacket. The Cioch jacket is the same fabric as Paramo, so it is essentially a windshirt with a heavyweight baselayer attached as far a insulation/breathability is concerned, think warmer Marmot Driclime. The jacket has a full zip and pit zips for venting.
Resting insulation layer: Mont Bell Alpine down jacket
So the question is which mid layer to use:
Pata Capilene 4 Hoody:
very breathable, very comfy, both under the jacket and on it's own at night in the tent or in the sleeping bag.
Very breezy, so if I get a little warm, opening up the zips on my shell will really help.
if it is quite warm the Pata is to breezy to wear on it's own if there is any kind of wind.
Beyond custom thin softshell jacket.
Lightly brushed Schoeller fabric on the chest and front of arms, thinnest stretch Schoeller on the rest, similar to the Rab Boreas, but slightly warmer in front.
Differential fabrics, keeping my front warmer (often a chilled area).
If I get to warm, just drop the Cioch jacket.
Reduced venting effect from opening my shell's zippers..
Far less comfy, wouldn't enjoy wearing it in the tent, would not wear it at night.
