Sleeping pads run the gamut from basic layers of foam that provide little cushioning, to deep inflatable mats for maximum comfort. Bear in mind that while foam mats may seem primitive, they’re essentially impervious to damage from any debris on the floor, tent pegs or whatever else might puncture your inflatable mat. If saving weight and space in your backpack is paramount, you can spend serious money on an ultra-light inflatable mat. However, such mats are less durable and need careful looking after – many even come with a repair kit. If you’re going to be camping in very cold weather, look for a model designed for this purpose that’s constructed from temperature-regulating fabrics – some even have down inside. Self-inflating mats are also available.
