Whether we're getting out there by foot, bike, or car, we don't want our creature comforts to weigh us down on the trail. The Ultra 3R Sleeping Pad provides loft and insulation for our evenings close to the earth without the added mass that some inflatable pads inherently have. Texpedloft microfiber insulation and an R-value of 2. 9 can keep us comfortable through the summer and the shoulder seasons, and if we need a little extra warmth, the Ultra 3R comes in a double size so we can cozy up with our camp companion.
