Head to head
Therm-a-Rest Z Lite Sol vs NEMO Switchback (2027)
Head-to-head: Therm-a-Rest Z Lite Sol versus NEMO Switchback, the two leading folding foam pads compared on comfort and packability.
Therm-a-Rest Z Lite Sol
The indestructible folding foam pad that never punctures.
- R-value (ASTM): 2.0
- Weight (regular): 14 oz (410 g)
NEMO Switchback
A plush-for-foam folding pad with metalized heat reflection.
- R-value (ASTM): 2.0
- Weight (regular): 14.5 oz (415 g)
Our recommendation
Choose the Switchback for better cushioning and a tighter pack fold. Choose the Z Lite Sol for the lowest price and the longest track record. Both are R-2.0 summer pads and winter layers; comfort is the real difference.
Cushioning design
The Switchback's hexagonal nodes are thicker (0.9 in) and shaped to nest, giving foam-pad users the plushest ride available in the format. The Z Lite Sol's egg-crate pattern is thinner and firmer, which some back sleepers actually prefer.
Packed size
Nesting nodes let the Switchback fold flatter; the Z Lite's accordion is bulkier for the same length. Both ride outside the pack for most hikers, so the difference is tidiness more than volume.
Price and availability
The Z Lite Sol is cheaper and sold everywhere, with decades of thru-hiker validation. The Switchback costs a bit more and justifies it in comfort. Neither will ever puncture, which is the point of both.
Choose Therm-a-Rest Z Lite Sol if…
- You want the cheapest reliable foam pad
- You prefer a firmer sleep surface
- You value the longest proven track record
Choose NEMO Switchback if…
- Foam pads have always felt too thin to you
- You want the most compact foam fold
- You will use it as a winter layer under an inflatable
Questions, answered
Which is warmer?
Effectively tied: both rate R-2.0 under the ASTM standard with reflective films.
Which lasts longer?
Both compress slowly over years. The Z Lite's foam has the longer documented service history; the Switchback's dual-density foam resists compression well.
Can either work as a sole winter pad?
No. At R-2.0 both are summer pads alone and winter layers only when stacked under an insulated inflatable.
