A Contemporary Take on Therm-a-Rest Classic.


This is the self-inflating bad boy that started it all. Riffing on the classic Therm-a-Rest® mattress of yore, this is the workhorse of contemporary car camping comfort. It's built to last with time-tested materials and construction, and makes a fine addition to truck beds and basecamps everywhere.

    Features

  • Light, soft fabrics are especially comfortable.
  • 1.75-inch thickness delivers great warmth and support.
  • Self-inflating foam core expands when unpacked.
  • Durable, classic design.

Limited Lifetime Warranty

Every piece of Therm-a-Rest gear is designed to endure the rigors of your time in the backcountry. We offer a Limited Lifetime Warranty on all products, except electronic devices, which have a 2-year Limited Warranty.
