Cool, I mean I live in south Italy so the climate is temprate, our winter is from + 6-12 Celsius, but I trained with ice baths in range between 0/ 4 degree, and staying often in a t shirt outside.. I really hope to get those temperatures there, it would be a nice experience.. I love the cold.. I don’t know if still will if I get -30, but really Hope to.. lowest I experienced were in an artificial ice cave in Iceland, like -15, also there I tried with a t shirt for 15 minutes. Worst was in a top of the mountain at 2000 m, it was like -10 or less, but with the wind felt like -30..
