Basic- lined lightweight jacket, layers of tshirts, sweatshirts, turtle necks, 2 pair of walking shoes, knit hat, gloves, rain gear. I never take jeans and always lined wind pants and leggins, jeans are just too bulky, take for ever to dry and tend to get and stay damp (plus I never rewear anything). Plus- dining wear.
I always do laundry off ship in Skagway, done in a little over an hour with their fast propane dryers, enough time for writing out and mailing some postcards.
