I have not yet found gloves that work well down to -30 (C) let alone colder so I use either Canadian Armed Forces arctic mitts (the white ones with the wool liner and the fleece patch on the back) in combination with wool liner gloves or some two fingered "gloves" I found at Canadian Tire intended for use by snowmobilers (also with wool liner gloves). It would seem that to be warm enough, gloves end up too bulky to have any real dexterity. I simply pull off my mitts and let them hang by their retainer cords (paracord through the sleeves just like when I was a 2 year old) when I need real dexterity to operate a camera or the like.
I still use Canadian Armed Forces style Sorel boots that I special ordered from the local hiking store. As long as i can dry the liners out every night they work well.
For the Parka, you really can't go wrong with the Canada Goose line, they seem to have a suitable Parka for every outdoor job or adventure requirement.
