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.
  • The standard or wide width options are highly recommended for adequate coverage when used in ground sleeping scenarios. Our Standard is our original Wide, we just decided to offer an even wider version

  • Proudly made in the USA.


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