Big Agnes took the already popular Q-Core SL insulated sleeping pads and sweetened the deal by making them even lighter. The Q-Core SLX sleeping pad uses a quilted design to give you the comfort, stability, and support needed for a good night's rest. The SLX's integrated layer of superlight high loft synthetic insulation provides the heat barrier needed for three-season use or cold conditions. Utilizing one-way inflation and quick deflation valves, this pad sets up easily and tears down quickly when you're ready to go. Combined with ripstop nylon materials and aviation-grade TPU lamination, this pad will give you the reliable, durable comfort you need for all your adventures.
