Warm, packable THERMOLITE® insulation works with a heat-reflective film to trap body heat and reflect it back at you to prevent heat loss

This pad has an R-value of 4.5, which makes it best for adventures in cold weather; it provides considerable insulation from ground temperature

Most sleeping pads we sell range from 1.0 (good for warm weather) to 5.5+ (for use in extreme cold); the higher the R-value, the more insulated the pad

3.25 in. thick pad has larger 3.5 in. outer chambers to keep you comfortably cradled in the middle of the pad

Proprietary I-Beam construction reduces weight and provides consistent stability and comfort

Save your breath for the adventure ahead, and use the included upcycled pad inflation sack to inflate

Durable, lightweight nylon double ripstop fabric is quieter than many pad materials on the market

Aviation-grade TPU lamination technology offers a high weld strength and ultimate dependability

Antimicrobial treatment inside the pad prevents microorganism growth

High-volume valves with microadjustments allow fast inflation/deflation and easy fine-tuning to your preferred firmness

Individually inflated and tested at the Big Agnes factory, ensuring 100% quality performance

For sleeping on frozen ground, increase thermal insulation by adding the Big Agnes 3rd Degree Foam Pad (not included)

Includes protective storage sack, replacement valve seal, 3M repair patches and a pad inflation sack made from upcycled excess pad material (color varies based on material)
