Pros & Cons

Reasons to buy:

User Reviews

  • Lightweight and compressible, with comfort and high quality.
  • Roomy enough for someone with broad shoulders; cozy for all sleepers.
  • Although it’s a down bag, the shell is water resistant, and will keep you warm even when the outside gets damp.
  • You can move the down around the bag to customize where you want extra warmth, and Western Mountaineering will even add down for you.

Expert Reviews

  • Extremely lightweight and packable.
  • Roomy enough that you can roll over in your sleep.
  • Testers felt this 30° bag provides comparable warmth to a bag with a 20° rating.
  • Zipper is a YKK coil zipper that will provide years of durability with stitched stiffening tape to prevent snags.
  • Continuous baffles allow you to move the down within the bag if needed, to provide extra warmth to feet or upper body.
  • Down-filled draft collar and draft tube along the zipper prevent cold air from entering the bag, and the cold zipper never touches your skin.

Reasons NOT to buy:

User Reviews

  • Expensive but you get what you pay for.

Expert Reviews

  • Price. However, with proper care, this bag should maintain its loft for ten or twenty years.
  • Must be washed in a front-loading washer.
