Big Agnes REM sleep pads are designed to provide years of comfortable nights in the backcountry. Our air chamber pads have gained a huge following due to their light weight and small packed size. Insulated Air Core pads – winner of the prestigious Editor’s Choice Award from Backpacker magazine in 2004 – take the best features of our popular Air Core and add PrimaLoft™ synthetic insulation to create the ultimate air chamber pad. Two Track pads are constructed using a lightweight die cut foam core. Hinman pads are solid foam core pads that deliver comfort and value.
