Head-to-Head Breakdown
Strengths & Weaknesses
NEMO Tensor All-Season Ultralight Insulated
- Best Overall at OutdoorGearLab, CleverHiker and Treeline Review
- R-value 5.4 at 14.1 ounces, enough for spring and fall nights
- The Vortex pump sack is Switchback Travel's favorite design and one of OutdoorGearLab's best tested
- OutdoorGearLab's tester found it hard to stuff back into its sack
- Outdoor Life flagged significant failure potential with the valve
- The rectangular Regular costs $20 more than the mummy, and there is no Short size
Big Agnes Divide Insulated
- Best Budget at Switchback Travel and Outdoor Life, and a Budget Buy at CleverHiker
- R-value 4.0 covers most 3-season trips, says Switchback Travel
- A full 20 x 72 inch rectangle with 3.25 inches of padding that side sleepers like
- 23.5 ounces on CleverHiker's scale, over half a pound more than the Tensor
- Switchback Travel finds vertical baffles less comfortable than horizontal or boxed ones

The Verdict
Our Bottom Line
Three of the eight publications in our research name the NEMO Tensor All-Season their best sleeping pad: OutdoorGearLab after testing 12 pads side by side on guided trips, CleverHiker after more than 3,000 trail nights on pads, and Treeline Review after six years of field testing. Switchback Travel ranks it a close second. The Therm-a-Rest NeoAir XLite NXT also collects three Best Overall awards, but two come from guides written by the same reviewer, Chris Carter, at GearJunkie and Switchback Travel. The third sits on an Outdoor Life page last updated in February 2025.
