A double-skin tent with a sewn-in groundsheet is recommended for snow camping. There are two main advantages of a double skin tent: the air space between the inner and outer provides some insulation, and condensation forms on the outer of the tent, if the inner layer is made of a ‘breathable’ material. Sewn-in groundsheets do not generally slip on snow. Separate groundsheets should be securely pegged down.
Most good quality modern bushwalking tents are suitable for snow camping, but some modifications may be required. These include cords attached to the bottom eyelets of the tent, and bearing plates (billy lids or aluminium discs) on the ground for tents with weight bearing poles. The bearing plates stop the poles from disappearing into the snow. To avoid losing them, drill a hole into each one, and tie one end of a cord through it, and the other to a bottom eyelet of the tent. The sloping sections of the tent need to be taut and of sufficient pitch to allow snow to slide off. A vestibule (an unfloored tent area outside the inner tent but inside the fly) is virtually essential.
