Overview

Built as a warmer alternative to a USGI poncho liner, this piece is intended for hunters and outdoorsmen who want a versatile layer for camp and sleep systems. It can also serve as a sleeping bag liner or ground cloth, giving it multiple uses when space and weight management matter. The continuous-filament Apex insulation is paired with a water-resistant RhinoSkin shell, and the construction avoids quilting to eliminate cold spots and improve drape. Its compressible design makes it easy to pack, though it is still a dedicated insulation layer rather than a standalone shelter solution.

Long DescriptionThe Kifaru Doobie is designed to replace the USGI poncho liner and are MUCH warmer. They are also great as a sleeping bag liner or ground cloth. Our Apex insulation is continuous filament - so strong that no quilting is needed. Plus, it has a better "feel" and draping capabilities - no quilting, so there are no cold spots. Coupled with our water resistant RhinoSkin Shell, you get immediate warmth and protection. Best yet, the Doobie is very compressible due to the state of the art materials used. Same great stuff we use in our sleeping bags.

Considerations & Trade-offs

  • Designed as a replacement for the USGI poncho liner, so it is purpose-built for that role rather than a general-purpose blanket.
  • Its warmth and protection come from the described insulation and water-resistant shell, which may be more than needed for users who only want a light liner.
  • The product description emphasizes compressibility and drape, but it does not provide detailed size or coverage specifications here, so fit and use-case should be checked before purchase.
