Across the Sleeping Pad Index

Where it sits in the market

Each comparison answers a buying question in plain English, names the typical value, and shows how many current pads were compared.

Across the Sleeping Pad Index

R-value

4.3

0.2 higher R-value than typical

Typical R-value
4.1
Products compared
5 current pads

Higher R-value than 3 of the 5 compared pads.

Based on 5 current sleeping pads with qualifying R-value data.

How this comparison works

“Typical” means the median: the middle value after the compared pads are ordered from lowest to highest.

A pad is included when its current R-value has product/value evidence that explicitly supports ASTM F3340 and is not a manufacturer estimate. Products without data that meets this rule are not included.

Pads in this comparison

  • Sea to Summit UltraLight Insulated, Regular: 3.1
  • Exped Ultra 3R, Rectangular: 3.2
  • Sea to Summit Ether Light XR Insulated, Regular: 4.1
  • REI Co-op Traverse Insulated Air Pad, Medium: 4.3
  • REI Co-op Helix Insulated Air Sleeping Pad, Medium: 4.9

9 current pads

Heavier than 6 of the 9 compared pads.

Based on 9 current sleeping pads with comparable weight data.

How this comparison works

“Typical” means the median: the middle value after the compared pads are ordered from lowest to highest.

A pad is included when its current reference-variant weight is published and available for comparison under OutdoorSpecs rules. Products without data that meets this rule are not included.
