After taking it out for it's second jaunt to the far North I decided that my self-modded Polish Laavu is not my shelter of choice. For the space I get, I feel the weight and effort to set it up is too much to be justified. I've been looking at Wayland's Adirondack tarp mod he recently designed as a future possibility for any further Arctic trips, but have also been looking at the various different types of tents and shelters available. I was wondering what people feel makes up an Arctic tent/shelter? What should I be looking for in the designs/products?
