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

Weight

410 g

60 g lighter than typical

Typical weight

Products compared
9 current pads

Lighter 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.
