What each one does well, and costs you
Big Agnes Divide Insulated
- R-value 4 at $110 is the cheapest insulated air pad here.
- Uses Thermolite synthetic insulation as well as reflective film, which is rare at this price.
- A genuine 50-inch-wide double for $229, cheaper than two singles.
- 3.25 inches of loft, the same as the much more expensive Zoom UL.
- 22.4 ounces is eight more than the Zoom UL for slightly less warmth.
- Vertical baffles give a flat surface with none of the Rapide's edge cradling.
- Big Agnes lists the same weight for the 66-inch and 72-inch versions, which is either a rounding artefact or a data error on their side.
- No published fabric denier.
Klymit Insulated Static V Peak
- R-value 4.2 for $100 — about half the cost per point of R-value of the ultralight air pads.
- 23 inches wide as standard and 30 in the Extra Large, both wider than most pads here.
- 75-denier polyester shrugs off tent grit that would worry a 20-denier pad.
- Real synthetic fill alongside the reflective film, so it doesn't rely on film alone.
- 22 ounces is heavy for a three-season backpacking pad — more than a pound and a third.
- Two and a half inches of loft leaves a heavy side sleeper on the ground.
- Mouth inflation only, and moisture inside an insulated pad is a long-term problem.
- Klymit's model naming (Peak, Summit, Base, Lite Eco) makes it hard to tell the line apart on a shelf.
