Product Description:

  • The Ultra Burrow is Hammock Gear's lightest ultralight offering.
  • Made with 7 denier ripstop nylon fabric featuring a DWR (durable water-resistant) coating to repel moisture.
  • Internal calendared finish ensures down proof construction.
  • Generously filled with ethically sourced 950 fill power down for superior insulation on the top and sides of your body while eliminating ineffective insulation underneath.
  • Eliminates less insulating elements found in most sleeping bags like a full-length zipper, hood, and backside materials to save weight and space.
  • Suitable for use with ground pads or underquilts to keep you warm down to its specified temperature rating.
  • A wide width option is highly recommended for adequate coverage when used in ground sleeping scenarios.
  • The Standard width is now 55" wide, the Wide is 60" for even more coverage
  • Proudly made in the USA.


  • Ultralight design suitable for both ground and hammock sleep systems.
