Sleeping pad
Overview
A sleeping pad is a portable mat used under a sleeping bag or quilt to provide insulation from the ground and additional comfort while lying down.
Key points
- Reduces conductive heat loss to the ground.
- Available as closed-cell foam, self-inflating, or air pads.
- Comfort and insulation vary by thickness and construction.
- Thermal performance is often described using an R-value.
- Durability and repairability are important considerations.
Details
Sleeping pads serve dual roles in backpacking shelter systems: they insulate and cushion. Closed-cell foam pads offer durability and reliability with modest comfort and insulation values. Self-inflating and air pads can provide greater thickness and comfort, with varying degrees of insulation depending on internal design and materials.
Thermal performance is frequently summarized by an R-value, where higher numbers indicate more resistance to heat flow. Choosing an appropriate R-value depends on expected ground temperatures, personal comfort, and how much clothing or additional insulation is used.
Air and self-inflating pads may require care to avoid punctures. Many hikers carry small patch kits for field repairs. Foam pads, on the other hand, are more resistant to damage but can be bulkier.
By pairing a suitable sleeping pad with a sleeping bag or quilt, hikers create a combined system that addresses both top and bottom heat loss during overnight rest.
