Sleeping Pad for Camping: 4 Pads for Tents and Vans Compared

Choosing a sleeping pad for camping gets more complicated when the same pad needs to fit a tent, a van platform and a friend's floor. A pad over an existing mattress has a different job from one placed directly on the ground. Start with what sits underneath, then consider warmth, cushioning and what you can carry.
Quick answer
Checked on 21 October 2026. Pick the Therm-a-Rest NeoAir XLite NXT for low carrying weight, or the Z Lite SOL for foam that cannot deflate. Choose the NEMO Tensor All-Season for the highest listed R-value here, or the Sea to Summit Ether Light XR Insulated for the deepest cushioning.

How we compared them
The NomadsToolsLab team read the manufacturer product pages on 21 October 2026 and checked each Amazon US listing with a US address. The comparison covered R-value, thickness, weight and packed size. One useful distinction: thickness is not warmth, since the thickest pad does not have the highest listed R-value.
R-value, thickness and the choice between foam and air
The air pads offer more cushioning depth than the foam option. That extra depth does not tell you which pad has more insulation, so compare warmth separately.
The Therm-a-Rest Z Lite SOL uses closed-cell foam rather than an airtight chamber, so a small puncture does not make it deflate. It asks you to accept a firmer surface and a bulky folded package. Air offers more cushioning, with the practical tradeoffs described below.
The four pads side by side
| Pad | R-value (maker) | Weight | Packed size | Thickness |
|---|---|---|---|---|
| Therm-a-Rest NeoAir XLite NXT (Regular) | R-value (maker): 4.5 (ASTM F3340) | Weight: 13 oz (0.37 kg) | Packed size: 9 x 4.1 in | Thickness: 3 in |
| Therm-a-Rest Z Lite SOL (Regular) | R-value (maker): 2 | Weight: 14 oz (0.41 kg) | Packed size: 20 x 5 x 5.5 in | Thickness: 0.75 in |
| NEMO Tensor All-Season | R-value (maker): 5.4 (standard not named) | Weight: Depends on size | Packed size: Depends on size | Thickness: 3.5 in |
| Sea to Summit Ether Light XR (Regular) | R-value (maker): 4.1 (ASTM-tested) | Weight: 470 g | Packed size: 20.5 x 11 x 11 cm | Thickness: 10 cm (3.9 in) |
From the makers' pages, read on 21 October 2026: NeoAir XLite NXT, Z Lite SOL, NEMO and Sea to Summit.
Therm-a-Rest NeoAir XLite NXT
Therm-a-Rest NeoAir XLite NXT (Regular)
Pick the Therm-a-Rest NeoAir XLite NXT if carrying weight matters, because the Regular weighs 13 oz. The limitation arrives at pack-up: CleverHiker found it slower to fully deflate than pads with a dump valve.
Allow time to empty it before packing rather than expecting a quick release of air. CleverHiker also rated the included pump sack below average, so its inclusion alone should not decide the purchase.
Therm-a-Rest Z Lite SOL
Therm-a-Rest Z Lite SOL (Regular)
Pick the Therm-a-Rest Z Lite SOL if you want no deflation risk, because its closed-cell foam does not rely on an airtight chamber, so a small puncture does not cause deflation. The consequence is a firm sleeping surface with little cushioning, a limitation CleverHiker highlights.
It makes sense on a van platform that already has a mattress, where another deep cushion may be unnecessary. Leave room for the folded pad, though: CleverHiker also describes it as bulky to pack.
NEMO Tensor All-Season
NEMO Tensor All-Season (Regular Mummy)
Pick the NEMO Tensor All-Season if insulation is your priority, because NEMO lists the highest R-value in this group at 5.4. CleverHiker cautions that the thin top fabric needs care around sharp objects.
The Amazon option linked here is the Regular Mummy. Check the exact shape before comparing carrying weight or packed size, since both depend on the version you choose. NEMO does not name the R-value standard on its product page.
Sea to Summit Ether Light XR Insulated
Sea to Summit Ether Light XR Insulated (Regular)
Pick the Sea to Summit Ether Light XR Insulated if cushioning depth matters most, because it is the thickest option here. CleverHiker found that its surface can feel clammy against bare skin.
Consider whether bare-skin contact will be part of your sleeping setup. The integrated pump sack is included, but CleverHiker also found it could pop off the valve during inflation.
Choose for the surface beneath you
On a van platform with a mattress already, consider whether you need another cushion or simply a foam layer. The Z Lite SOL fits the latter role, provided you can accept its firmness and folded bulk.
For a tent in cold weather, make warmth the first filter. Then weigh the remaining compromises: carrying weight with the NeoAir, fabric care with the NEMO, or surface feel and pump attachment with the Sea to Summit. Sleeping in a van? See our mosquito nets and camping chairs for van life.
- Compare R-value separately from thickness. The deepest pad here is not the one with the highest listed insulation.
- Foam cannot deflate, but the Z Lite SOL offers little cushioning and takes up folded space.
- The NeoAir suits a weight-conscious choice, while the NEMO leads on listed R-value.
- Check the exact size and shape before comparing weight and packed dimensions, particularly for the NEMO.

FAQ
Does a thicker sleeping pad mean a warmer pad?
Not in this comparison. The Sea to Summit is the thickest, while the NEMO has the highest listed R-value. Use the insulation figure separately from cushioning depth.
Which pad makes sense over an existing van mattress?
The Z Lite SOL is an option when you want a foam layer rather than another deep cushion. Its limitations are firmness and folded bulk.
Which of these pads cannot deflate?
The Z Lite SOL uses closed-cell foam, which does not rely on an airtight chamber, so a small puncture does not cause deflation. That removes an air-pad concern, but does not give it the cushioning of the thicker options.
Why are the NEMO weight and packed size not listed here?
They depend on the size and shape selected. The Amazon version linked here is the Regular Mummy, so use that exact version when comparing those details.
