I hunt moose in Saskatchewan and you will need a pair of fleece pants for the waders and possibly neoprene socks. Check what king of lubricant was used on the bolt of your rifle or better yet just go the a gunsmith and have your bolt disassembled and lubricated with something that will not jell in cold temp, saw this happen twice in five hunts. If boats are used for transport then you will need a face covering to fight the windchill. One of the comments above was to talk to your outfitter, this is very good advice. The outfitter we use and all his personnel are Cree and do not talk much until they get a feel for who you are, and our first moose hunt was a learning experience to say the least.
