It's another layer though which makes a fair difference. If it's -2 in the mountains I will have my RAB rain jacket on too so maybe: undershirt, jersey, warm/windblock layer, rain layer and hope for the best.
I can't remember if I used an undershirt on TCR or not. I normally wear one but I'm really not sure now so I might lose the undershirt in the heat or get a lighter one than I currently have, like one of those Craft string ones.
Gabba are too bulky for what I want.
I only have one roubaix fleece jersey and I'm not cutting its arms off but finding another one might be an option.
I think a softshell might be overkill. If it's that cold I can just throw on the rain jacket and/or down jacket. Then again, if I find a warm gilet replacement perhaps I could get away without taking the down jacket?
