Big Agnes Insulated AXL Sleeping Pad - 20" x 72" Mummy

Sold Out

Ultralight and compact

Weighing in at less than a pound, this sleeping pad is an ultralight hiker’s best friend. It also compresses down to the size of a water bottle, so you never have to choose between comfort and pack space.

Temperature rated to 15ºF

Even on warm summer nights, it’s possible to lose body heat to the ground. This pad features a combination of PrimaLoft® Silver synthetic fibers and reflective Mylar to insulate against the cold and reflect your body heat back to you, making backcountry slumber much comfier.
