How to use this answer
Choose based on terrain, packed space and repair plans. This separates a useful measurement from a broad product label and helps identify which exact variant needs further checking.
Decision boundary
The listed values describe a product under its stated source conditions. They do not establish personal comfort, safety, stock, or fit in every shelter.
Insulation and dimension context
ASTM F3340-22 measures thermal resistance under controlled compression. Its R-value helps compare pads but cannot predict a universal safe air temperature; thickness is a different property. Check the exact variant and test method before using a number.
For this question, check: R-value and method, length, narrowest usable width, packed weight and repair needs. When a particular specification is absent, keep the decision open rather than treating a missing value as zero or assuming a universal fit.
Compare actual recorded values
The values below come from exact catalog variants. The table is an illustration of which measurements to compare, not a ranking or a recommendation. Open each card for the field source and revision notes.

| Naturehike Troues R2.4 Folding Foam Sleeping Pad — M | 2.4 | 0.77 lb (350 g) | 0.9 in (2 cm) |

Recheck manufacturer instructions and the exact year, size and SKU. The October 30, 2026 dataset does not verify real-time inventory, sale prices, field performance or a guaranteed safe temperature. If the key measurement for this question is unavailable, ask the maker or measure your own equipment before committing to a setup.
