Shaded cells mark the row where one has a measurable advantage. Weight, thickness, girth and shape are left unshaded on purpose: heavier is sometimes tougher, wider is sometimes warmer, and calling a winner on those would be an opinion dressed as a measurement.
What each one does well, and costs you
Klymit Static V Base
- $50 is a quarter of what most pads here cost, and it packs to 8 × 3 inches.
- 23 inches wide — wider than pads costing four times as much.
- 75-denier polyester is the toughest face fabric in this catalogue; it will outlive the lightweight pads.
- Klymit publishes the ASTM figure honestly rather than hiding it, which not every budget brand does.
- R-value 1.3 means no meaningful insulation — on ground below about 50 °F you will feel it through the pad.
- 18.7 ounces for an uninsulated pad is heavier than insulated pads at three times the price.
- Blow-up-by-mouth only; no pump sack is included, so moisture goes straight into the pad.
- Two and a half inches of loft with hard V-chambers is firm and not especially comfortable.
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.
