I just joined this forum and this is my first post. I am taking 6 days mountaineering course at Mt. Baker on August 18 -23 through AAI company.
I got a gear list for this course but about the clothes, it doesn't say which is mandatory and which is optional and how many each item to bring. It said to bring hiking sock, short underwear, baselayer bottom, baselayer top, midlayer top, softshell pant, softshell jacket, hardshell pant, hardshell jacket, and insulated synthetic hooded jacket. My question is which is mandatory and which can be optional depend on the weather or so for August or all of them are mandatory? Also how many should I bring each item like how many softshell pants I need to bring? I want to pack small to have space for others and carry lightest as possible during the trip.
