Another great innovation from the folks at Big Agnes, the Sleeping Giant Memory Foam Kit is the ultimate in sleeping pad comfort. Memory foam is an open cell foam that molds to the curves of your body and reduces pressure points to offer unsurpassed comfort. This is the same memory foam that you can find as a topper for your mattress at home. The kit comes with Memory Foam and a durable 70 denier rip stop nylon cover with a wrap style closure. You simply slide your pad into the cover with the memory foam on top and you are ready to enjoy an incredible night's sleep. The Sleeping Giant Memory Foam Kit adds a 3.5 R Value to the temperature rating of your pad, but the exact rating depends on the pad you use. Stuff Bag included. Fits pads: 78 x 20 Weight: 2 lbs. 12 oz. Pack Size: 7 x 20 Color: Green and Grey Import.
