Airbeds, sleeping mats & seat pads
A good airbed or sleeping mat offers the double benefit of comfort and, most importantly, insulation against ground cold. Thicker cushioning means greater comfort, but also more bulk and weight. Self-inflating mats are especially comfortable and practical. They also allow you to choose how firm or soft a surface you sleep on. Important: Self-inflating mats must only be rolled, and never folded, unless they are specially designed for folding.
