The most important thing you have with you on a camping trip is a good tent, the second most important is a comfortable sleeping bag. The next item in the list is something nice to sleep on. It is not nice to feel cones, stones or roots underneath, so invest in a good air bed, a comfortable self inflating mattress or a practical tent bed.
If you want to sleep with high comfort, our recommendation is to use a sleeping mat that is at least 5 cm thick but if you need to save weight you can go down to 3 cm but for most people this is only the back position. For those who are out and about in cooler climates, there is also a sleeping surface with built-in insulation.
For those of you camping, the advantage of our thicker bedding is that they provide a more bed-like experience than the mattresses as they are more stable and distribute the weight better than the air mattresses. But here is our recommendation to at least walk on a 7.5 cm reclining bed to get really good comfort.
