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)
