Quick answer: choose a sleeping pad by R-value first (warmth), then weight and comfort. For three-season backpacking, an inflatable pad with an R-value of 3–4.5 and a weight under about 500 g is the sweet spot. Closed-cell foam pads are cheaper and can’t puncture, but are bulkier and less comfortable. Side sleepers usually need a pad at least 7 cm (2.5–3 in) thick.

R-value explained
R-value measures how well a pad stops heat escaping into the ground. Since 2020, most major brands test to the ASTM F3340 standard, so values are comparable across brands.
| Season | Recommended R-value |
|---|---|
| Summer, warm nights | 1–2 |
| Three-season | 2.5–4 |
| Cold shoulder seasons | 4–5 |
| Winter / snow camping | 5+ (or stack foam + inflatable) |
Types of sleeping pad
| Type | Pros | Cons |
|---|---|---|
| Air pad | Lightest for its warmth, packs small, comfortable | Can puncture; can be noisy |
| Self-inflating | Durable, comfortable | Heavier and bulkier |
| Closed-cell foam | Cheap, can’t puncture, doubles as a sit pad | Bulky, firm, low R-value |
Other things to check
- Thickness: 6–8 cm for side sleepers.
- Width and shape: mummy shapes save weight; rectangular pads stop arms sliding off.
- Noise: some insulated air pads crinkle when you move.
- Valve: one-way valves and separate deflate valves make set-up quick.
- Pump sack: keeps moisture from your breath out of the pad.

Frequently asked questions
Can I combine two pads?
Yes. R-values add up, so a foam pad under an air pad is a common winter set-up.
How do I fix a leak?
Find it with soapy water, dry the area and use the patch kit. Carry a patch kit on every trip.
Are inflatable pads cold?
Uninsulated air pads are cold. Choose an insulated pad with the right R-value.
