What the specs mean
The listed R-value is 11.8. Check its stated test method: ASTM F3340 values are useful for comparing insulation under controlled conditions, not a guaranteed temperature limit. Thickness describes cushioning and cannot substitute for R-value. This version is listed at 25.0 in (64 cm) wide; compare that with the tent's narrowest usable floor width.
Read the exact variant
Regular is the recorded option. Other sizes or revisions may have different dimensions, weight, or test labels.
