Mountain Hardwear Ghost Whisperer Sleeping Bag

The insulation is 900-fill power Q.Shield™ goose down. Q.Shield™ is down that has been treated with a DWR coating so that it retains loft while resisting moisture. This down is RDS (Responsible Down Standard) certified and DWR coating is fluorine free. 

The body fabric is Whisperer 7D x 10D Ripstop nylon. This lightweight body forms a performance mummy cut that maximizes the warmth to weight ratio. The zipper is a ¾ length anti-snag zipper and features fabric reinforcement. At the hood, a one-handed draw cord facilitates the hood closure adjustments. 

Quilted construction prevents the downshifting of the insulation and six chambers in the hood ensure that even loft is retained. A down-filled face gasket blocks drafts at the hood opening and an insulated draft guard blocks drafts along the zipper. Finally, the comfort foot box allows feet to be in a natural position.

The Mountain Hardwear Ghost Whisperer Sleeping Bag comes with both a mesh storage sack and a compression sack.

Side by side compression comparison with the Sea to Summit Ember III.

If you’re looking for a performance bag that is both super lightweight and compressible, this might just be the bag for you. The performance mummy cut is form fitting; comfortable and ergonomic, but you certainly won’t be hauling extra materials up the mountain. The one downside is that it’s not exactly roomy once you’re zipped in. 

The most appealing part of the design is how compressible this bag is. When fully compressed, this bag is tiny and won’t take up much space in the backpack. Side by side with the Sea to Summit Ember III it’s visibly smaller.  While the Ember III is rated for colder temperatures, it’s also not a full sleeping bag, while the Ghost Whisperer is a full mummy. 

A feature I really like on this bag is the glow in the dark slider on the zipper. It’s only glow in the dark on the outside and at first I was wondering why, but I suppose not having a glowy thing in your face when you're trying to sleep is the idea. 

I was also curious about the down-filled face gasket, which turns out, is essentially extra draft tubing in the hood opening; a welcome addition when battening down the hatches. 

Final say? If you don't mind a tight fitting sleeping bag, this bag boasts an incredible weight to warmth ratio, and the compressibility is next level.
