What is R-Value in a Sleeping Pad

The R-Value measures a sleeping pad’s ability to insulate you from the cold ground.

  • A higher R-Value means better thermal insulation and more warmth during sleep.

  • Pads with R-Value 1–2 are suitable for summer camping.

  • R-Value 3–4 works well for spring and autumn conditions.

  • R-Value 5 or higher is designed for winter use or cold mountain environments.

When choosing a sleeping pad, always consider the R-Value to match your camping conditions — it’s the key factor for warmth and comfort outdoors.
