NEMO Tensor Trail vs NEMO Flyer
In short: The NEMO Flyer costs $50 less; the NEMO Flyer is warmer by 1.4 points of R-value; the NEMO Tensor Trail saves 7.1 oz; the NEMO Tensor Trail is 3.5 inches thick against 2; one is air and the other self-inflating.

What each one does well, and costs you
NEMO Tensor Trail
- 3.5 inches of loft at 13.9 ounces — the same thickness as the warmer Tensors for two ounces less.
- Quiet in exactly the way the rest of the Tensor line is.
- $190 undercuts the All-Season by $30 and the XLite by $20.
- Mummy and rectangular options at the same price in the Regular.
- R-value 2.8 runs out below about 40 °F of ground temperature; a frosty night on this needs a foam pad under it.
- Only $30 cheaper than the All-Season, which is nearly twice as warm — the value case is narrow.
- 20-denier fabric, like the rest of the line.
- A thick summer pad is a lot of volume to carry for insulation you could get from foam.
NEMO Flyer
- 21 ounces is the lightest self-inflating pad in this catalogue, three ounces under the closest comparison.
- R-value 4.2 from foam rather than film, so a puncture costs comfort rather than the whole night.
- Silent, and warm to the touch in a way reflective-film pads never are.
- $140 is at the bottom of the three-season price range for this much R-value.
- Two inches of loft is thin — side sleepers will feel the ground through it.
- Packs to 10 × 6.5 inches, roughly twice the volume of an ultralight air pad.
- Self-inflation is partial, as always; expect to top it up.
- Sold in mummy cut only, so there is no rectangular version for restless sleepers.
