Oh honey ! That ' s a tricky one they ' ve taught you . I couldn ' t even fathom how hard it must make your life . Are you talking to someone ? <| sep |> He hasn ' t had to work a day in his life , but he does , everyday . <| sep |> This is so pretty ! I really love the colors . Thank you for taking the time to make this ! <| sep |> OP , listen to the layer preacher . There is no situation for running that you need warm jacket . I have a very light wind breaker and tights with some windprotection . On rainy days a slightly heavier jacket with DWR . Here ' s what I use under 10 C technical tshirt , maybe use shorts on fast runs 5 C cheap thermo layer shirt , wind resistant hat 0 C buff for neck , running cloves , wind resistant hat 5 C same , because now air is dry and it feels better 10 C Second buff for head . Add cheap thermo pants , maybe warmer cloves and hat , add tshirt on the thermo . On slow long runs a fleece shirt on top of technical t shirt 15 C only slow runs so , fleece shirt on top of thermo layer . Ski gloves , two buffs for head , wool hat with wind protection layer .
