A good sleeping pad does more than cushion you from the ground. It also insulates you from cold that can seep up through your sleeping bag. The right pad depends on how you camp: car campers can prioritize thickness and plushness, while backpackers need to watch every ounce and packed inch.
We looked at six pads from Sea to Summit and NEMO that cover a range of styles, from self-inflating foam pads to ultralight air pads. The key differences come down to type, R-value for warmth, thickness, and how small they pack. For more on getting a good night’s rest outdoors, see our guide on how to sleep comfortably when camping.
Every specification on this page comes from the manufacturer’s own product page, checked on 28 October 2026. We have not used these products ourselves, so the picks are based on published specifications only.

How we chose these
- Type: Self-inflating vs. Air Self-inflating pads use open-cell foam that expands on its own, offering a balance of cushioning and convenience. Air pads are lighter and pack smaller but require inflation, often with a pump sack.
- Warmth (R-Value) The R-value measures how well a pad resists heat loss to the ground. Higher numbers mean more insulation. An R-value around 2 is fine for summer; 4 or above works for three-season use; 5+ extends into colder conditions.
- Thickness and Comfort Thicker pads provide more cushioning, especially for side sleepers. Self-inflating pads typically range from 1.5 to 3 inches, while air pads can reach 4 inches or more.
- Weight and Packed Size Backpackers and bikepackers care about grams and liters. Self-inflating pads are generally heavier and bulkier, while air pads can weigh under a pound and pack to the size of a water bottle.
Specs are for the Regular size unless noted. Weights shown are packed weights for Sea to Summit pads (includes stuff sack) and manufacturer-stated weights for NEMO pads. ‘Not stated’ means the maker did not provide that number.

Which one fits you
| Your situation | Look at | Why |
|---|---|---|

| You’re a weight-conscious backpacker | Ultralight XR Insulated Air | Light, compact, with enough insulation for three-season trips. |

Practical tips
- Match the R-value to the seasons you camp in. An R-value of 2 is fine for warm summer nights, while 4 or higher handles three-season use and 5+ extends into colder weather.
- Self-inflating pads are easier to set up but heavier and bulkier. Air pads pack smaller and weigh less but require inflation, often with a pump sack.
- If you sleep on your side, look for a pad with at least 2.5 to 3 inches of thickness and a wider shape to keep your hips from bottoming out.
- Check the pad’s packed size against your backpack or gear storage. Even among air pads, packed dimensions can vary significantly.
