The Mountain Hardwear Ghost Whisperer Hoody ($380) is an ultralight and packable down jacket designed to provide just enough insulation to guard against a chill. Its 800-fill-power down, thin 10-denier shell fabric, and pared-down feature set give it one of the best warmth-to-weight ratios on the market. However, the minimalist build comes with a few downsides: namely, durability and insulation. Ounce-counting adventurers will have no issues with these tradeoffs, but generalists and those who get out in cold conditions will want a hardier and warmer jacket.

Mountain Hardwear Ghost Whisperer Hoody
For this season's top puffies, see our guide to the Best Down Jackets.
The Ghost Whisperer sacrifices warmth for a low weight and packability. With just 2.6 ounces of 800-fill down, it’s considerably less insulated than competitors. For reference, the Patagonia Down Sweater Hoody—a wildly popular lightweight down jacket and one of our top recommendations for 3-season use—features 4 ounces of 800-fill-power down. The similarly intentioned Arc’teryx Cerium uses 3.2 ounces of 850-fill-power down, in addition to synthetic insulation in high-exposure areas. It doesn’t take much of a mathematician to see that the Ghost Whisperer’s insulation is on the low side of the standard lightweight down jacket.
The Ghost Whisperer is a go-to jacket of mine for summer mountain evenings and shoulder-season day missions, where it usually provides adequate warmth to guard against a chill—provided it’s not super windy (more on this in the Weather Resistance section below). Temperature ratings are tough to give as there are so many variables involved, but in general, I’d recommend the Ghost Whisperer for temperatures in the upper 40s to low 60s. My favorite way to use the jacket is as an emergency layer stuffed away into my running vest on summit missions. I’ll whip it out when the going gets exposed, wear it while I enjoy the views, and most likely start the descent wearing it before delayering once I warm up again.
The Mountain Hardwear Ghost Whisperer starts to show its limits during early- or late-summer nights in the mountains. Wanting to travel super light, the jacket was my insulation during a September fastpacking trip in the Glacier Peak Wilderness. It provided enough warmth during the day (I put it on during trailside breaks and even ran a few miles in it after sunset), but it was no match for the evening chill. With the Ghost Whisperer layered over a Patagonia Capilene Cool Lightweight t-shirt and lightweight merino wool base layer, I still had to bundle up in my sleeping quilt to stay warm while hanging out around camp. I packed for my trip knowing I’d need the additional warmth of my sleeping bag from dusk to dawn, but the jacket’s limitations are still worth sharing.
I tested the Ghost Whisperer in a women’s small, which weighed 7.4 ounces on my home scale (Mountain Hardwear lists its weight at 8.5 oz.). This is significantly lighter than most lightweight down jackets on the market, which is thanks to the Ghost Whisperer’s thin shell, trim cut, and limited feature set. To compare, the Arc’teryx Cerium is known for its high warmth-to-weight ratio and weighs 10.2 ounces for the women’s version, but offers more warmth with 3.2 ounces of 850-fill down and some synthetic insulation. Another lightweight model, the Rab Mythic G, checks in at 8.9 ounces for a women’s medium, but is significantly warmer. Added up, the Ghost Whisperer is ridiculously lightweight, which has earned it a place in my toolkit for all-day trail runs, mid-summer summits, and as an emergency layer.
The Ghost Whisperer packs away fairly easily into its hand pocket, which features an internal carabiner clip for attaching to your harness—a nice feature for multi-pitch climbs. That said, I don’t love the idea of wearing the Ghost Whisperer climbing: The shell is so thin that it would be too easy to pop a hole in the fragile fabric, and the resulting feather explosion would not be ideal. Still, I could see bringing it along for some extra warmth while belaying in dry conditions.
Down jackets are inherently comfortable, and the Mountain Hardwear Ghost Whisperer is no exception. I think the jacket’s streamlined silhouette contributes to its comfort: It doesn’t get in the way of movement, and you don’t feel like the Michelin Man while wearing it. The thin shell fabric is really supple and easy-moving, too—far more so than a thicker material. That said, there’s no stretch in the fabric, so it doesn’t match the comfort of a jacket like the Mountain Hardwear Stretchdown Hoody.
Almost all outdoor apparel that prioritizes a low weight will do so in exchange for durability, and the Ghost Whisperer is a case in point. Its 10-denier shell fabric makes me hesitant to wear it for much more than very specific use cases when weight-savings matters, although I’m always tempted to wear it around town given its sleek fit. It’s an undeniably fragile jacket, and even stuffing it into the recesses of my climbing pack or running vest makes me a bit nervous. I'm also hesitant to take it multi-pitch climbing, even though its low weight and packability make it an appealing option. Instead, I reach for a synthetic insulated jacket like the Patagonia Nano-Air Ultralight. If this jacket rips while climbing a chimney or shoving my arm deep into a fist crack (which it has and does), the sheet-like insulation means there’s no feather explosion high on the wall.
The Ghost Whisperer offers virtually nothing in the way of weather protection. The wind whips through its thin shell, and Mountain Hardwear doesn’t even mention a durable water-repellent finish, so we have to suppose it's not present. By contrast, the Arc’teyrx Cerium features strategically placed synthetic insulation in areas prone to moisture, which offers an extra dose of assurance for variable mountain weather. To keep weight and packability on track, the Ghost Whisperer is a down jacket and nothing more. This shouldn’t be an issue if you keep the Ghost Whisperer in its lane (fair-weather use only). However, the lack of DWR does have aesthetic implications: DWR also guards against oils and dirt, meaning the Ghost Whisperer is more prone to staining than most down jackets.

Longevity
Choosing durable outdoor gear and keeping it in use for longer is one of the best ways to reduce environmental impact. Our proprietary longevity rating assesses factors like overall build quality, materials, fabric denier, component durability, and real-world performance. A green check indicates that we expect the product to be long-lasting relative to its peers, a yellow check mark indicates average longevity, and a red X indicates a product that may have a limited lifespan.
Responsible Down
The Responsible Down Standard (RDS), developed by Textile Exchange, is the leading certification for responsibly sourced down and uses third-party audits throughout the supply chain to verify animal welfare, responsible farming practices, and safe working conditions. Recycled down is another responsible choice that helps reduce demand for newly sourced down while keeping existing materials in circulation. A green check mark indicates a product uses responsibly sourced or recycled down, a yellow check mark indicates the brand sources responsible or recycled down for the majority of its products but does not specify it at the product level, and a red X indicates the product does not use responsibly sourced or recycled down.
Recycled Materials
Recycled materials are prevalent in outdoor gear, with nylon, polyester, wool, and down among the most common, but the composition varies widely. A green check mark indicates the product is made with a substantial amount of recycled materials (100% recycled or the core fabric that makes up most of the product is recycled), a yellow check means it contains a moderate to small amount of recycled materials, while a red X means there are no recycled materials in the product.
Bluesign Approved
Bluesign Technologies, based in Switzerland, operates a third-party textile management system that ensures materials are manufactured to strict environmental, chemical, and worker safety standards. A green check mark indicates a product is either a Bluesign Product (contains at least 90% Bluesign-approved fabrics and 20-30% Bluesign-approved accessories) or features a significant amount of Bluesign-approved materials. A yellow check mark means it uses some Bluesign-approved materials but less than the aforementioned category, and a red X means there are no Bluesign-approved materials in the product.
Responsible Manufacturing
This criterion evaluates a brand’s commitment to fair wages, safe working conditions, and reducing environmental impact through certifications and programs like Fair Trade Certified, Fair Wear Foundation, Worldwide Responsible Accredited Production (WRAP), and the Fair Labor Association, while also recognizing brands that manufacture primarily in the U.S. or Europe under strict labor and environmental regulations. A green check mark indicates a brand meets our responsible manufacturing criteria, while a red X means it does not.
Recycled and/or Reduced Packaging
Packaging can add significant waste to outdoor gear purchases, so many brands work to reduce its impact by using recycled materials, incorporating Forest Stewardship Council-certified paper products, and minimizing plastic and paper use. A green check mark indicates a brand uses recycled or reduced materials across all of its packaging, a yellow check indicates moderate or limited use of recycled or reduced packaging, and a red X indicates the brand does not make either of these efforts.
Repair Services
Repair services extend the lifespan of outdoor gear and reduce overall consumption, though programs vary widely. Some brands offer comprehensive repairs for a range of issues, while others provide limited or no repair support. A green check mark indicates a robust repair program, a yellow check mark indicates limited repair services, and a red X indicates the brand does not offer repair services.
Resale and/or Recycling Services
Resale and recycling programs help keep outdoor gear in circulation longer and out of landfills, ranging from trade-in resale platforms that offer store credit to take-back initiatives that recycle products at the end of their usable life. A green check mark indicates a brand offers both resale and recycling programs, a yellow check mark indicates it offers one or the two, and a red X indicates it offers neither.
Carbon Footprint Tracking
This criterion evaluates whether a brand measures, reports, and works to reduce its greenhouse gas emissions using established frameworks such as the Higg Index, Greenhouse Gas Protocol, or The Change Climate Project. A green check mark indicates a brand publicly reports greenhouse gas emissions data, sets clearly defined reduction targets, and uses established tracking frameworks such as Higg or The Change Climate Project. A yellow check mark indicates the brand tracks emissions and outlines reduction goals but provides limited data, lacks science-based verification, or does not clearly report progress. A red X indicates the brand does not appear to track greenhouse gas emissions or provides so little information that its efforts cannot be verified.
Annual Impact Report
Annual impact reports provide transparency and accountability by outlining a brand’s sustainability efforts across areas such as material sourcing, greenhouse gas emissions, waste, water use, supply chains, and packaging. A green check mark indicates a brand publishes a detailed, brand-specific impact report that closely aligns with our sustainability criteria and leaves little room for ambiguity. A yellow check indicates a brand provides some relevant sustainability reporting but lacks detail in key areas or is covered only briefly within a parent company report. A red X indicates a brand does not regularly publish an impact report.
Given the Ghost Whisperer’s streamlined, lightweight design, there’s not much in the way of features: A simple hood with a rear cinch to seal in the warmth (the hood does not fit over a helmet), two hand pockets, a drawcord adjustable hem—and that’s it. It’s a simple, pared-down feature designed to minimize weight—exactly what you need and nothing more.
Tester: 5’6” 140 lb.; bust: 35"; torso length: 19"; waist: 28"; hips: 38"
Size tested: Women’s small
I tend to wear a women’s small in most outerwear, although recently I’ve found myself reaching for size medium jackets more and more—especially if I plan on layering underneath. However, I tested the Mountain Hardwear Ghost Whisperer in a women’s small and have nothing to complain about with the fit, which was true to size. I can wear a t-shirt, a long-sleeve base layer, and even a light fleece underneath. Plus, the jacket fits well underneath a rain jacket or hardshell. Overall, its trim fit makes it a great layering piece.
Rab Mythic G ($525): Ultralight Insulation for Colder Temps
There aren’t many down jackets that clock in as low on the scale as the Ghost Whisperer, but the Rab Mythic G comes close. Not only that, but it’s absolutely bursting with down, packing in 50% more insulation than the Ghost Whisperer at a much higher fill power (1,000 vs. 800). It also uses a heat-reflective lining that prevents heat loss. Taken together, the Mythic G is a much warmer jacket for just 1.5 ounces more, but the tradeoffs are a more fragile shell (7D vs. 10D) and an outrageous price tag. It’s worth noting that the Mythic G packs into a stuff sack rather than an integrated stuff pocket, which isn’t our favorite design. But if you need ultralight insulation for below-freezing temps, it doesn’t get any better. For more, see our review of the Rab Mythic G.
Arc’teryx Cerium Hoody ($400): Warmer and More Moisture-Resistant
The Cerium Hoody isn’t nearly as ultralight as the Ghost Whisperer, but it’s a warmer, more protective jacket that’s still competitively lightweight at 10.2 ounces for the women’s small. While the Ghost Whisperer is a nice pairing for the kind of mild temperatures you’ll find on summer evenings and shoulder-season days, the Cerium can handle more wintery conditions (down to around freezing), thanks to an ounce more down at a higher-fill power and a healthy dose of synthetic insulation in areas prone to wetting out, such as the armpits, collar, and wrists. It all adds up to one of the best ultralight down jackets for cold weather. If you're interested in learning more, read our review of the Arc'teryx Cerium Hoody.
The Ghost Whisperer is one of our favorite ultralight down jackets, with a low weight, small packed size, and streamlined feature set. Its attractive, low-profile fit also works well in casual environments. However, the thin fabric is fragile and requires care.

The Cerium offers extremely lightweight and packable warmth for technical pursuits like alpine climbing and backcountry skiing. Its streamlined fit is ideal for layering, too. However, given the price point, thin fabrics, and trim fit, we don’t recommend this jacket for everyday use.

Hold up, what!? We can’t believe Rab managed to pack this much warmth into such a lightweight jacket. You’ll pay a pretty penny for it, and it's unsurprisingly fragile. But the Mythic G is the only sub-10-ounce jacket we know of that can handle freezing temperatures.

The Mountain Hardwear Ghost Whisperer Hoody is a compelling down jacket for weight- and space-conscious adventurers who don’t need a ton of warmth. We love it for not-too-cool summer nights or quick summit breaks, but don’t recommend pushing it much lower than the mid-40s Fahrenheit—and it won’t do you much good in the wind or rain. Ultralight backpackers, fastpackers, and trail and mountain runners will appreciate its minimalist design and super low weight. Climbers, however, should likely opt for a more durable synthetic insulated jacket. For $360, there are certainly more versatile, durable options, but if you’re looking for a down puffy that takes up the least amount of space in your pack, it’s hard to beat the Ghost Whisperer.
