Our Verdict

Product Discontinued
The text in this review compares the Phantom 15 to other top models available in 2015. Our current Backpacking Sleeping Bag review provides in-depth comparisons among today's best bags.

This excellent bag combines 800-fill down with a great fit. The Phantom is equipped with one of the most comfortable hood designs of any bag we tested. This bag offer campers and backpackers a moderately lightweight bag that's viable below freezing.

Traditional sleeping bags with zippers and hoods have fixed girths that can be a large drawback for backpackers and climbers that cross multiple climates or wear clothing inside the bag. We've found that quilt style sleeping bags are more versatile, lighter weight, and more comfortable in a wider range of conditions. Our testers much prefer quilts for multi-day trips.

Our Analysis and Test Results


The Mountain Hardwear Phantom 15 is one of our highest rated traditional style three-season down bags. It exemplifies a well-designed, comfortable, and efficient sleeping bag, and its significantly more affordable than slightly better bags.

Outside, the Phantom is protected by superlight 15 Denier ripstop nylon. Inside, 800-fill goose down provides a luxurious amount of puffy loft. While weight and compressibility are top factors when choosing a sleeping bag, its fit that separates a good bag from a great bag. Disregarding the stretchy Montbell Down Hugger, the Phantom is the best fitting all-purpose bag reviewed in this category. The Phantom 15 fits a wide variety of body types without being too wide or too skinny for the masses. Its available in a Womens cut, which is shorter than the Regular cut. We prefer the fit of the Phantom to the fit of the Marmot Plasma, which is slightly wider and not available in a Womens cut.

All other sleeping bags weve reviewed, except for the Marmot Plasma, have inferior hood and neck baffles. The Plasmas is, more or less, as comfortable as the Phantoms, but its slightly less efficient (heavier). Were comparing minute details here, but theyre important because its what surrounds your face and neck.

The Mountain Hardwear Phantom 15 has one of the most comfortable hoods of any sleeping bag we've ever tested.

Unfortunately, the zipper on the Phantom is extremely prone to snagging. Like terribly likely to snag. This author once spent 10 minutes freeing a caught zipper in the middle of the night (much worse than most other bags). While this is rather annoying, the problem is akin to a small blemish on a flavorful fruit. You can deal with it.

Like all sleeping bags with fixed girths, the Phantom is significantly heavier and less versatile than quilt style sleeping bags. Our Backpacking Sleeping Bag Review discusses the advantages of quilts, which are found in the Ultralight Sleeping Bag Review.

Best Application

All-purpose multi-day camping.


The Phantom is a great value. Its not as light or as fancy as the Marmot Plasma 15, but its lower price make it a sure bet for someone looking for a quality do-it-all down bag.
