Head-to-head foam sleeping pad comparison

NEMO Switchback vs Therm-a-Rest Z Lite SOL

These two folding closed-cell foam pads share the same 72-by-20-inch Regular footprint and a published R-Value of 2. The useful split is in the details: NEMO adds 0.15 inch of listed thickness and a hexagonal foam pattern, while Therm-a-Rest is a half ounce lighter with a classic dimpled surface.

The short answer

Which one should most people buy?

Both are simple, dependable folding foam pads. The better default is the one whose small published advantages match the way you carry and use it.

The NEMO Switchback Ultralight Sleeping Pad, Regular is the better default because it keeps the same 72-by-20-inch Regular footprint, 2 R-Value, and 20-by-5-by-5.5-inch packed size as the Therm-a-Rest while listing 0.9 inch of thickness. NEMO also describes its dual-density Axiotomic foam, hexagonal nodes, Hypnoelastic zones, and metallized thermal film. The advantage is not enormous, which is exactly why it is useful: it gives the everyday buyer a slightly thicker published profile without changing the familiar folding-foam routine.

The Therm-a-Rest Z Lite SOL Sleeping Pad, Regular has a real reason to win for the right packer. Therm-a-Rest lists a 14-ounce Regular pad, 0.75-inch thickness, the same 72-by-20-inch dimensions, the same R-Value of 2, and the same 20-by-5-by-5.5-inch packed dimensions. It combines softer foam on top, denser foam on the bottom, heat-trapping dimples, and a ThermaCapture surface. Pick it when that half-ounce difference and its long-established folded-panel format are what you want. For most people starting from a blank slate, the Switchback’s added listed thickness makes the clearer all-purpose choice.

Choose by routine, not camp-kit snobbery.

Start with the tent, pack, and setup rhythm you repeat instead of treating a small spec difference as a universal score.

Buy the NEMO Switchback if

You want a folding foam pad with the slightly thicker listed 0.9-inch profile while keeping the standard 72-by-20-inch Regular size, 2 R-Value, and compact 20-by-5-by-5.5-inch folded package. NEMO’s hexagonal-node construction and dual-density foam are concrete reasons to choose this version when you value its stated surface design.

Skip it if: the Z Lite SOL’s half-ounce-lighter listed weight or its dimpled foam arrangement is the particular detail you want.

Buy the Therm-a-Rest Z Lite SOL if

You want the 14-ounce Regular pad and Therm-a-Rest’s molded closed-cell foam construction: softer foam on top, denser foam on the bottom, heat-trapping dimples, and a reflective ThermaCapture surface. Its published packed dimensions and R-Value match NEMO’s Regular, so this is a close alternative rather than a different product category.

Skip it if: you want the Switchback’s 0.9-inch stated thickness and hexagonal-node surface to be the deciding details.

Routine check: both products are folding closed-cell foam pads with the same listed Regular length, width, packed dimensions, and R-Value. Check your shelter floor, sleep system, and current manufacturer guidance rather than treating this comparison as a temperature, comfort, or safety guarantee.

How we reasoned

The criteria behind the pick.

This is a close comparison because these products start in the same place: both are Regular-size, folding, closed-cell foam sleeping pads. Both makers list a 72-by-20-inch pad, a 2 R-Value, and a 20-by-5-by-5.5-inch packed size. A comparison that pretends one is an automatic upgrade would miss the buyer’s actual choice.

We focused on the differences the manufacturers publish that are most likely to shape selection: thickness, listed weight, foam construction, surface pattern, and the reflective layer each maker describes. NEMO lists 0.9 inch of thickness and 14.5 ounces for the Switchback Regular. Therm-a-Rest lists 0.75 inch and 14 ounces for the Z Lite SOL Regular. The small weight difference favors Therm-a-Rest, while the thicker published profile favors NEMO.

The surface descriptions are also meaningfully different. NEMO calls out dual-density Axiotomic foam with hexagonal nodes and Hypnoelastic zones, along with a metallized thermal film. Therm-a-Rest calls out softer foam on top, denser foam on the bottom, heat-trapping dimples, and a ThermaCapture surface. We use those descriptions as product-selection details, not as a substitute for trying a sleep setup or as a promise of a specific comfort result.

NEMO wins the overall recommendation because the shared footprint, R-Value, and packed size leave its listed 0.9-inch thickness as the clearer broad-use advantage. Therm-a-Rest remains the better pick for buyers who value its listed 14-ounce weight and its particular foam-and-dimple construction. Neither manufacturer specification replaces current product guidance or a realistic check of the conditions and equipment you plan to use.

Before checkout

Questions before checkout.

Answers match the FAQ structured data on this page.

Which foam sleeping pad is the better pick for most people?

The NEMO Switchback Regular is the better pick for most people choosing between these two closed-cell foam pads. NEMO lists a 2 R-Value, 72 by 20 inch dimensions, 0.9 inch thickness, 14.5 ounce minimum weight, and a 20 by 5 by 5.5 inch packed size for its Regular. Choose the Therm-a-Rest Z Lite SOL Regular instead when its one-half-inch thinner profile, one-half-ounce-lighter listed weight, and 20 by 5 by 5.5 inch packed dimensions better suit the way you pack.

Do both Regular pads have the same R-Value?

Yes. NEMO lists an R-Value of 2 for the Switchback, and Therm-a-Rest lists an R-Value of 2 for the Z Lite SOL. That shared number is useful context, but it is not a guarantee about comfort or a precise temperature recommendation for every sleeper, shelter, bag, surface, or condition.

What is the practical size difference between the Regular pads?

Both manufacturers list the Regular pads at 72 inches long and 20 inches wide. NEMO lists the Switchback at 0.9 inch thick and 14.5 ounces, while Therm-a-Rest lists the Z Lite SOL at 0.75 inch thick and 14 ounces. NEMO lists a 20 by 5 by 5.5 inch packed size; Therm-a-Rest lists the same Regular packed dimensions.

What distinguishes the foam surfaces?

NEMO describes its dual-density Axiotomic foam with hexagonal nodes and Hypnoelastic zones, plus a metallized thermal film. Therm-a-Rest describes molded closed-cell polyethylene foam with softer foam on top, denser foam on the bottom, heat-trapping dimples, and a ThermaCapture surface. Those are real design descriptions, not a promise that either surface will feel the same to every person.

Does this comparison use live prices or marketplace ratings?

No. This page avoids live price, stock, and marketplace-rating claims. The recommendation is based on the manufacturers’ published dimensions, thickness, weights, packed sizes, R-Values, foam construction descriptions, and stated use categories. Confirm the current product listing and manufacturer details before buying.
