Nemo Vector Sleeping Pad Spaceframe baffles (die-cut trusses of low-stretch fabric) eliminate the springiness found in competitor pads. This creates a more stable sleep surface, better for rolling side-to-side and for keeping your elbows off the ground when reading a book. Undulating Lateral Baffles offer the most comfortable and unobtrusive topography for sleeping pads, which combined with the height, stability, quiet fabrics, and paltry weight and packed size make this series the ultimate in pad design. The integrated foot pump is fast and efficient, and vastly superior to using your lungs, especially after a day on the trail. The Vector features a metalized film layer to offer insulation at an ethereal weight. The Insulated version adds a layer of continuous filament insulation for even more warmth.
