A week at a helicopter-access lodge is the trip on this site where the kit costs real money, because nothing on the hill is lent: the board or the skis, the boots, the skins, the avalanche transceiver, shovel and probe, the harness for glaciated ground, and the shell that keeps a whiteout out. The lodge brings the beds, the meals, the guides and the sauna, and both Purcell and Mistaya will rent some of the safety kit if you ask in advance.
These are the prices behind the winter packing list, which I wrote from the splitboard after two winters at Purcell, added up two ways: the essentials, and everything on the list with the camera. One honest note on the first line: where the list offers a board or skis, the budget prices the cheapest part, the skins; a full splitboard setup is priced further down.
