Cascade Designs Therma-Rest

This item is primarily a collector's piece. While it is technically a functional sleeping pad, its age means the internal materials and seals may have degraded, so we cannot guarantee it will hold air or provide reliable insulation in the field.

New Old Stock (NOS) refers to merchandise that was manufactured in the past—in this case, the 1970s—but was never sold or used. It remains in its original, factory-sealed packaging, essentially acting as a time capsule of outdoor gear history.

This is a compact, short-length pad measuring 20 by 47 inches. It is significantly smaller than most modern adult sleeping pads, which typically run 72 inches or longer, so it is best suited for ultralight setups or as a torso-length mat.

It is unlikely. The self-inflating foam inside relies on open-cell structure and airtight seals that often break down or compress permanently over several decades. If you open the package, you should expect to manually inflate it, assuming the valve and material integrity hold.

Because the value of this item is tied directly to its factory-sealed, vintage condition, opening the packaging significantly diminishes its status as a collector's item. We recommend keeping it sealed to preserve its historical integrity.
