The king of cold weather sleep comfort The Insulated Static V Luxe SL is an insulated, lightweight, luxury sleeping pad. The sleeping pad is the thickest and warmest pad in the Static Series line at 3.5” and a R-Value of 6.5. It’s the perfect balance of weight, width, and length in a luxury size. Slightly slimmer than the Insulated Static V Luxe, weight is trimmed by using a lightweight fabric and a slight taper at the bottom third of the pad. The exclusive V-chamber design conforms to the shape of your body while maintaining ample, lofted air pockets. The result: side, back, and stomach sleepers can all rest comfortably on a generous bed of air.
