How to choose a sleeping pad

Read R-value, then width, then weight. Thickness is comfort. A three-season backpacking pad for most sleepers is about R 3 to 4. Cold sleepers should go higher. Air pads need a repair kit. Foam cannot puncture and will not keep a cold sleeper warm alone.

R-value is the ground

R-value is resistance to heat flowing out of you and into the dirt. Two pads of the same thickness can have very different R-values. A summer pad used on frosty ground is how people decide they 'sleep cold' when the pad was the problem.

Stacking foam under an air pad adds R-value and saves the night if the air pad fails. It is not a second mattress.

Width is why side sleepers wake up

A regular mummy pad is a compromise with your elbows. If you sleep on your side, buy the wide and accept the grams. A restless night costs more miles than the pad weighs.

Air, foam, or both

Insulated air is the backpacking default. Uninsulated air is a summer toy. Closed-cell foam is the lunch seat and the backup. Self-inflating pads are comfortable and slower to pack; fine at a car camp, less ideal when you are counting volume.

FAQ

What R-value for winter?

Often 5 or more, sometimes foam plus air. This guide is not a full winter system.

Do I need a pump?

A small pump sack keeps moisture out of the pad. Inflating with your lungs works and adds condensation inside the tubes.
