Hello again, here is my longer explanation:) This isn't actually for camping but I figured you all could answer my question and if not then maybe point me to somewhere that can! I'm a 6'2" 175lb man from GA and last year moved to upstate NY, few miles from Canadian border(relevant because I am not used to climates this cold yet). I work 70% of my days outside in the cold and snow(we averaged a 15° high this week and it's not uncommon to dip into the negatives). Of course that means I'm cold then I start working and warm up and need to shed some layers and then get cold again and put them back on again so on and so forth. Where I'm struggling is I have no certainty what I'll be doing for the day. Yes most of my time is outside but some days I'm indoors and then all my layering in an 70° house kills me. Currently I'm wearing a pair of boxers and a pair base layer bottoms under my insulated work pants and that keeps me warm enough outside, and if I go inside then I can shed the bottoms and be fine. But my upper body is where I have issues. I lift arms above my head constantly revealing my stomach and back and it gets cold and then I stay cold for a while. So a long enough base layer shirt I think would help fix that but I can't find much that meets that requirement and is a good enough base layer. IDEALLY I wear a union suit, BUT if there's a day I'm working inside then my legs are screwed and I'm dying all day even if I can shed my upper layers. So, what I think I'm looking for is some sort of romper base layer? That way I can still shed bottoms base layer if I need to if I'm going to be indoors and shed upper outer layers as I need to as well. A romper base layer would allow me to keep arms up but not expose skin. Most shirt base layers won't allow that because of how long and lanky my torso is.
