Understand the number
R-value describes resistance to heat flow: higher values indicate greater insulation. It is not a temperature forecast or a comfort score. A large air mattress may feel soft yet offer limited insulation. Choose a pad as part of the complete sleep setup and consult its manufacturer’s intended conditions.
Compare the main types
Foam pads are simple and do not need inflation. Air pads can pack small, but require inflation and a plan for punctures. Self-inflating pads combine foam and air, often with a larger packed size. REI’s guide sets out these construction differences and the insulation role of a pad.
Shelter, insulation and dry bedding work together.
Make the comfort test realistic
Lie down for several minutes rather than pressing a palm into the display model. Turn onto your side and back. Check pad width at shoulders and hips, the space for your pillow, and whether you slide off the edges. Use the inflation method recommended by the maker.
Check fit before departure
- Compare the pad dimensions with the usable tent floor, especially tapered ends.
- Inflate at home early enough to notice a slow leak.
- Locate the valve and learn how to close and open it properly.
- Keep a compatible repair kit and instructions with an inflatable pad.
- Write down what worked after the first night before buying another accessory.
