The Good

The Bad

The Verdict

  • Versatility—can be packed as either a 15 or-30 degree bag.
  • Solid interior appointments—draft guards, zipper guides.
  • An exterior pocket on the mummy hood holds a pillow.
  • A bit heavy for a 600-fill, 15-degree down bag.
  • Insert only covers the torso, leading to cold feet when used in chillier conditions.
  • Slightly pricey, even for a 15-degree bag.

A versatile design concept that doesn’t quite deliver on its promise of being a single-quiver solution, but will suffice if your adventure schedule calls for two bags and your checkbook can only support one.

Sierra Designs Pyro Maniac 15/30

Depending on your patience for making gear adjustments and willingness to pay $320 for a 600-fill bag—even one that claims to be a single-quiver solution—the Pyro Maniac may represent a solid value. If those attributes don’t describe you, clock a few extra shifts and pick up a couple bags whose designs are more focused.      

Materials
The Pyro Maniac is insulated with run-of-the-mill 600-fill down, which still has a better compressibility and weight-to-warmth ratio than synthetics. There is a large pocket sewn onto the top of the bag’s torso in which one insets a down blanket that adds an additional 15-degrees of warmth.  

Features
Theoretically, the additional warmth in the core area translates to the rest of the body, but in practice the lack of additional insulation in the lower body can lead to cold feet. Our testers initially thought it was a clever scheme, but after hands-on experience some felt it was clunky to work with and cooled on the idea.

How We Tested It

The sleeping bags were tested by a crew of about a dozen from August 2011 through July, 2012 on camping trips in Oregon, Washington, Colorado, New Mexico, Wyoming, and Norway.

The products featured in this test have been loaned to the Gear Institute. For more on our policies regarding editorial objectivity and sample returns, see here.
