Light and packable for minimalist fast hikes, the 1 in. thick Sea To Summit Ultralight SI sleeping pad uses vertical coring to keep body-contact areas warmer with great support and packability.

  • Features

    • Core has smaller die-cut holes in body-contact areas (shoulders, hips and feet) to keep you warm; larger die-cut holes in non-body contact areas help reduce weight and bulk
    • One-way inflation valve can be reversed and used to prevent air from being drawn back in; allowing you to roll the mat without fighting re-inflation as you roll
    • This pad has an R-value of 2.6, which makes it best for adventures in cool weather; it provides moderate 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
