The Best Sleeping Pad Review

Types of Pads
The 17 sleeping pads we tested can be divided into six different categories based on their construction.

Closed Cell Foam
The “classic foam pad” refers to these highly durable and versatile mats. They’re lightweight but bulky. They’re best for those on a budget, for sleeping directly on the ground, or for extended trips that demand the most reliable sleeping pad. Everyone from novice backpackers to the world’s best Alpinists use closed cell pads.

Self-Inflating Foam
Open cell foam is glued to the top and bottom of the pad’s interior. Self-inflating pads are comfortable, hold their shape well, but are neither the most compact nor lightweight.

Standard Air Core
Open chambers are filled with air like an inflatable pool mattress. These require a lot of air to blow up, collect moisture inside (which needs to be drained out), and are affordably priced. Though thicker than self-inflating foam pads, air core construction is often bouncy, can be slippery, and is not warm. Standard air core pads make a good first backpacking pad.

Synthetic Insulated Air Core
Synthetic insulation is glued to the underside of the sleep surface. Their thickness makes them comfortable and the insulation makes them reasonably warm, but they also require a lot of air to inflate and collect moisture. Generally modestly priced, synthetic insulated air core pads make for a good budget winter pad.

Down Filled Air Core
A small amount of down is stuffed inside the pad. This insulates you from the snow and ice below. These pads are thick and comfortable, very warm, but expensive and not very light. They need to be inflated with a pump, which is generally included, because moisture from your lungs will degrade the down inside the pad.

Structurally Insulated Air Core
The Therm-a-Rest NeoAir series dominates this category. Internal baffles minimize air circulation and insulate your body from the cold beneath. Unfortunately the edges of these pads collapse under load and make the pad feel narrower than it is (their baffles are oriented horizontally, as opposed to vertically like most other air core pads). NeoAir models offer the greatest amount of warmth and comfort for their weight, and pack down to a shockingly small size. These are arguably the most technologically advanced sleeping pads available and offer the highest performance for multi-day mobile trips.

Criteria for Evaluation
We evaluated each sleeping pad based on the following criteria:

Weight
The weight of the pads we tested ranged from 9.1 oz. (Klymit Intertia X Frame) to 36 oz. (Exped DownMat 9). Weight is positively correlated with comfort: in general, the heavier the pad the more comfortable it is.

Packed Size
Closed cell foam pads are the bulkiest type of pad. Their large size generally prevents them from fitting within your pack. The smallest pad we tested was the Klymit Interia X Frame, which can fit in your pocket. The next smallest was the NeoAir XLite. See our specifications table above and in each individual review for packed volumes.

Durability
The Therm-a-Rest Ridge Rest SOLite and Z-Lite are the most durable pads we tested. Their closed cell foam resists extended use and abuse and allows the pads to serve purposes other than sleeping; they're the best pads for remote expeditions. Inflatable pads are less durable, but relatively easy to patch if you can find the leak. We found the Nemo Zor to be the least durable pad we tested.

Comfort
Here we evaluated how well each pad transformed rocks and roots into plush heavenly clouds. Although comfort is subjective – and one can quickly become inured to pains of the thin, ultralight pad – we came to the following general conclusions: thicker pads cushion the hips and knees better than thinner pads; flat surfaces are more comfortable for putting your head on than bumpy surfaces; grippier fabrics keep you and your pad attached for longer; square pads offer more surface area than mummy shaped pads, and the NeoAir’s horizontal air chambers are more comfortable than competing companies' vertical chambers. (Vertical chambers are generally larger and bumpier, have little internal structure, and can feel like an inflatable pool toy.) The most comfortable pad will depend upon your preferences. Top contenders are the Exped DownMat 9, Neo Air Trekker, and ProLite Plus. Our testers found the Klymit Intertia X Frame to be the least comfortable pad.

Warmth
A pad’s ability to insulate you from the cold below is a crucial concern for winter users when the temperature difference between your body and the ground can exceed 60 degrees. Two main factors influence warmth: a pad’s thickness (thicker is warmer) and air circulation (more reduces warmth). Winter sleeping pads aim to prevent the warm air at the top of a pad from mixing with teh cold air at the bottom of a pad. Unfortunately there is no industry standard for measuring R-Values (several companies are in the process of developing one). Our warmth variable reflects our experience testing the pads on ice and snow. The R-Value column presented above, and in each individual review, shows either the value from the manufacturer or from independent testing done by Backpacking Light. When comparing R-values know that the measurement is linear: a pad with an R-value of 5.0 is five times warmer than a pad with an R-value of 1.0. The warmest pad we tested was the Exped DownMat 9 followed by the NeoAir XTherm.

Inflation Method and Storage
You breath contains water vapor that can damage a sleeping pad over time. In warm weather vapor from your lungs enters the pad when you inflate it and leaves the pad when you deflate it. In cold weather, however, water vapor condenses into liquid form and remains inside the pad even after deflation. Some winter pads, such as the NeoAir AllSeason and XTherm, include stuff sacks that can be used for inflation. Other pads, such as the Exped SynMat and DownMat, have built-in hand pumps. Neither of these options is particularly easy or lightweight. Two other inflation options are the Nemo Disco Pad Pump and Therm-a-Rest NeoAir Pump Sack.

Editor's Choice Award: The Best Sleeping Pad
The Therm-a-Rest NeoAir XTherm is the highest performance all-purpose sleeping pad on the market. It's not only small, lightweight, and comfortable, but also very warm. The XTherm transforms cold snow and ice into a soft and supple air bed fit for a queen. This is the single sleeping pad our testers choose for winter trips and, if we were to have one single pad, we'd choose the XTherm.

Top Pick Award: Best Pad for Extra Comfort
The many people who car camp and backpack in roughly equal proportions will find the Nemo Astro Insulated to be slightly more comfort than the XTherm. This pad is heavy, a bit too much so for our preference, but it walks the fine line between being light enough for multi-day trips and well suited to the compact ground found in established campsites.

Top Pick Award: Best Pad for Ultralight
Fast and light adventures in all seasons call for the Therm-a-Rest NeoAir XLite. This is our highest rated pad for backpacking and all three-season exploits. It's significantly lighter and more compact than the Astro Insulated but doesn't have the warmth of the XTherm's built-in furnace. Nonetheless, the XLite is easily warm enough for occasional winter use; many multi-day trip aficionados will find the XLite to be their ideal pad.

Best Buy Award: Best Value Pad
Closed cell foam pads offer exceptional durability (you can't pop them) at bottom basement prices. The Therm-a-Rest Z Lite SOL blends tank-like durability with a reasonable packed size to create our favorite inexpensive pad. This pad is ideal both for the budget conscious and for the ultra hardcore: thru-hikers, alpine climbers, and mountaineers all depend on closed cell pads for the most ambitious objectives. Of all of the similar pads we've tested this is the warmest and, critically, the most compact.
