The A-Frame shelter (or double lean-to) is particularly useful given it's ease of construction and low material requirements: two shorter branches1 and one longer branch form the frame of your shelter, while the walls are simple stick-and-leaf constructions—the more leaves, the more insulation. In addition, the shelter is well-suited to the human shape: narrow near the feet and wider at the head, double lean-tos make efficient use of space, making it easier to find a suitable location to place the shelter. The small volume of the shelter also makes insulation more efficient.

  1. Finding one branch with a y-notch is preferable, as it avoids the need for cord and lashing—just drop the second branch into the notch. [↩]
