Hi, I want to buy a Bergans Sirdal pants but I´m between shell and insolated versions. I will use them in Alpine resort ski and I would like to use them all the season in coldest days and in warmers days.
My two options are:
A) Bergans sirdal Shell + X-bionic radiactor pants baselayer.
Pros: best breathability
better temperature in warmer days thanks to the fantastic thermal regulation of X-bionic radiactor
Cons: Maybe I will go cold in coldest days?

B) Bergans sirdal insulated without baselayer pants
Pros: good for coldest days thanks to the primaloft insulation
Cons: Will I be overheated on warmer days? Tha pants have zips to help refrigerantion but I don´t now if it will be enough to ski in warmer months.
