I get cold easily at camp. What is the lightest down puffy jacket with high fill power?

If you get cold easily at camp, I’d avoid chasing the absolute lightest jacket. The key is fill weight, not just fill power: a 1,000-fill jacket with 1.7 oz of down can be noticeably colder than an 800–900-fill jacket carrying 3–4 oz.

My picks

• Black Diamond Deploy Down 0.5 - $549.00 (Backcountry)

• La Sportiva Lumina 100 - $289.00 (Nordstrom)

• Mountain Hardwear Ghost Whisperer UL - $484.99 (Backcountry)

• Rab Mythic Alpine Jacket - $425.00 (Backcountry)

• Lightest:

— about 5.6 oz, 1,000-fill, but only ~1.7 oz of down. It's incredibly light, but better as a minimalist insulating layer than a seriously warm camp puffy.

• Best for your situation: Montbell Plasma 1000 Alpine — about 8.4 oz, 1,000-fill, with 3.4 oz of down. That's a much better balance if you routinely feel chilled sitting around camp.
• Best middle ground: La Sportiva Lumina 100 — roughly 5.9 oz, 1,000-fill, and 2.5 oz of down. Remarkably light while carrying substantially more insulation than the extreme ultralight options.
• If warmth is the priority: Rab Mythic Alpine is worth considering; it's heavier but designed more around actual warmth than shaving every gram.

My choice for a cold sleeper/camper: Montbell Plasma 1000 Alpine. I'd happily spend ~2–3 extra ounces over the Deploy for nearly twice the down fill.

If you tell me your typical nighttime temperature (e.g. 30°F, 40°F, 50°F) and whether you want a hood, I can narrow it down to the warmest jacket under your target weight.

If you get cold easily at camp, the absolute lightest jacket with the highest fill power isn’t necessarily the best choice for you.

Here is the catch: Fill power measures quality/loft (how well an ounce of down traps heat), but total warmth depends on fill weight (how many ounces of down are actually stuffed inside the jacket). The absolute lightest 900- to 1000-fill jackets (like the Montbell Go to product viewer dialog for this item. or Mountain Hardwear UL series) use very little down to shave ounces, meaning they act more like a light sweater than a cozy shelter against a chilly camp wind.

If you run cold, you want a balance: high fill power (800–900+) for efficiency and compressibility, paired with a decent amount of actual down weight and a hood , while still staying remarkably light.

Top options matching this sweet spot include:

If you want the absolute pinnacle of high fill power, this features mind-blowing 1000-fill power down and weighs a scant ~5–6 oz. Note: It is minimalist and delicate, so you'll want to treat it with care around campfires.

Uses top-tier 900-fill power down combined with heat-reflective TILT lining technology. It is exceptionally warm for how light and packable it is, making it a powerhouse for cold sleepers.

Packing 850-fill power hydrophobic goose down at around 11.5 oz, this is a warmer, more generously-filled option that won't break the bank compared to high-end alpine specialty brands.

Uses premium 850-fill power down paired strategically with synthetic Coreloft insulation in moisture-prone areas (like cuffs and shoulders). At ~10–11 oz, it punches way above its weight class in warmth.

To help narrow down the ideal pick, tell me:

• What kind of temperatures are you expecting at camp?
• Do you prefer having a hood , and are you looking for an active fit or a relaxed fit to layer underneath?

If low weight + high fill power is your priority, there are a few standout choices—but because you get cold easily at camp, I wouldn't automatically choose the absolute lightest jacket.

My picks

• Black Diamond Deploy Down 0.5 - $549.00 (Backcountry)

• Mountain Hardwear Ghost Whisperer UL - $484.99 (Backcountry)

• Feathered Friends Eos - $429.00 (Feathered Friends)

• Rab Mythic G - $550.00 (Nordstrom)

• Lightest: Black Diamond Deploy Down 0.5 — about 5.2–5.6 oz, 1,000-fill down. Black Diamond lists 148 g for men's medium, with only 1.7 oz of down. It's extraordinarily light, but that low fill weight means it's more of a minimalist insulation layer than a truly warm camp parka.

• Best ultralight choice for you: Mountain Hardwear Ghost Whisperer UL — 6.7 oz, 1,000-fill, with 1.9 oz of down. It's only about an ounce heavier than the Deploy but gives you a little more insulation. WIRED specifically notes that people who get cold easily may want something with more fill.

• Best if warmth matters more than absolute weight: Montbell Plasma 1000 — roughly 8.4 oz, 1,000-fill, with about 3.4 oz of down. That's a much more meaningful jump in insulation while remaining exceptionally light. CleverHiker calls it one of the best warmth-to-weight options they've tested.

• Warmth-first premium option: Rab Mythic G — 1,000-fill down plus reflective TILT technology. It's considerably heavier/more expensive, but better suited to someone who prioritizes warmth at camp.

What I'd buy in your situation

Montbell Plasma 1000. The key number isn't just fill power—it's fill weight. A 1,000-fill jacket with 1.7 oz of down can be colder than an 800-fill jacket containing 4 oz of down. Since you get cold easily, I'd sacrifice ~2 oz of jacket weight for substantially more down.

If you tell me the lowest temperatures you typically camp in (e.g. 30°F, 20°F, 10°F) and whether you want a hood, I can narrow this to the best 2–3 options and compare their actual warmth-to-weight.

If you get cold easily, chasing the absolute lightest jacket on Earth (like a 5-ounce extreme minimalist piece) might actually leave you shivering at camp. Ultra-minimalist jackets sacrifice down quantity and features (like pockets or a hood) to shave grams.

However, if you want the apex of high fill power (1000-fill) paired with an impossibly light weight and actual camp-worthy warmth, look at these top-tier options:

1. • Black Diamond Deploy Down 0.5 Pullover Hoody Go to product viewer dialog for this item. : Weighing a mind-blowing ~ $148g (~ 5.2oz) for a men's medium, this uses ultra-premium 1000-fill power goose down and a featherlight 4D/7D nylon shell. The catch: It's a half-zip pullover to save weight, which means it's hyper-minimalist. You can check it out via Black Diamond Equipment.
2. • Rab Mythic G Down Jacket Go to product viewer dialog for this item. : Weighing around ~ $312g (~ 11oz depending on size), it packs a massive punch with 1000-fill power goose down combined with a thermo-reflective TILT lining that bounces back up to 30% of your radiant body heat without adding extra weight. Because it has a full zip, proper pockets, and a full hood, it provides significantly more usable camp warmth than a true marginal pullover. Learn more on the Rab Equipment Site.
3. • Kailas 5000GT Alpine 1000FP Hooded Down Jacket Go to product viewer dialog for this item. : Another extreme-end contender utilizing 1000-fill power hydrophobic goose down and an ultralight shell designed for high-altitude base camps, balancing a high warmth-to-weight ratio while retaining a full-featured hood and pockets. View details on Kailas Gear.

Since you mentioned you get cold easily, would you prefer a full-zip jacket with a hood for maximum heat retention, or are you looking for the absolute lightest weight possible regardless of style?

If your priority is minimum weight + maximum warmth, my first pick is the Montbell Plasma 1000 Alpine Down Parka.

• Montbell Plasma 1000 Down Jacket - $329.00 (Lyst)

• 1000-fill-power down

• 8.4 oz / 237 g for the men's version

• About 3.4 oz / 96 g of down

• Hooded, with adjustable hem and cuffs

• Extremely compressible

• This is about as good as it gets for warmth per ounce. Independent testing also rates the Plasma 1000 among the best warmth-to-weight jackets available.

Other excellent choices

• Mountain Hardwear Ghost Whisperer UL Down Hoody - $485.00 (REI Co-op)

• Rab Mythic Alpine Light Down Jacket - $355.00 (Backcountry)

• Black Diamond Deploy Down 0.5 Hooded Jacket - $549.00 (Backcountry)

• Katabatic Gear Tarn Down Jacket - $251.20 (Outdoorline)

• Mountain Hardwear Ghost Whisperer UL — also 1000-fill and extremely light; a strong alternative if you prefer its fit/features.

• Rab Mythic Alpine Light — 252 g / 8.8 oz with 900-fill down, but only 80 g of down and synthetic insulation in the arms/shoulders/hood. It's more moisture-tolerant than an all-down ultralight jacket.

• Black Diamond Deploy Down 0.5 — 1000-fill and exceptionally light, but it's designed more as an active/alpine layer than a maximum-loft camp puffy.

• Katabatic Tarn — 850+ FP and a particularly good option if you want a little more durability/value.

One important point: fill power alone doesn't determine warmth. A 1000-FP jacket with only 2 oz of down can be colder than an 800-FP jacket containing 4 oz. Since you say you get cold easily at camp, I'd prioritize total down fill + hood + wind-blocking shell, not just the highest FP number. Rab explains the same distinction: fill power is primarily about the quality/loft of the down.

If you tell me the lowest temperature you typically camp in (e.g. 30°F, 20°F, 10°F), I can narrow this down to the lightest jacket that will actually keep you comfortable rather than merely being the lightest.

If you get cold easily at camp, searching for the highest fill power and absolute lowest weight is a great strategy, but a warning for cold sleepers : the absolute lightest jackets on earth (under 6 oz) use high fill power to save weight, but they stint on the total amount of down (fill weight). They are designed for high-output moving, not sitting around a chilly camp.

However, if you want the pinnacle of high fill power (950 to 1000FP) combined with minimal weight, these options balance extreme lightness with actual camp-worthy warmth:

Uses mind-boggling 1000-fill-power goose down . The jacket version weighs a scant 4.9 oz (139 g), but if you get cold, look at the Plasma 1000 Alpine Parka Go to product viewer dialog for this item. (which adds a hood and more down fill while staying remarkably light at around 8 oz). Check availability on the Montbell Official Site.

Features high-end, hydrophobic 950+-fill-power down and weighs roughly 6.8 oz (192 g). Unlike stripped-down competitors, it includes a fully adjustable hood, dual hand pockets, and an internal chest pocket, making it a favorite for cold sleepers on long trails. Details can be found via Zpacks.

Claiming an ultra-technical spot, it uses 1000-fill power down wrapped in a hyper-thin 4-denier shell, coming in around 5.2 oz (148 g). It's a half-zip minimalist piece, incredibly light, though best paired with an active layering mindset. Take a look at Black Diamond Equipment.

An upgraded, even airier version of the iconic Ghost Whisperer, packing 1000-fill-power down into a 7-denier shell at roughly 6.7 oz (190 g). It's super sleek, but because it's lightly filled to save weight, cold sleepers may need a fleece or wind shell over it when static at camp. Explore options on Mountain Hardwear.

If you want to pin down the right choice, tell me:

• What temperatures are you typically camping in?
• Do you strongly prefer having a hood and pockets?

I can help you decide whether an extreme ultralight 1000-fill jacket will keep you warm enough or if you need a slightly burlier option.

If you get cold easily at camp, I would not choose purely by the lightest jacket. The trick is balancing:

• Fill power = how lofty/efficient the down is (850–1000 FP is premium)
• Fill weight = how much down is actually inside (often more important for sitting around camp)
• Baffle design, hood, hem adjustment = big factors when you’re not moving

The lightest jackets often have very little down and are better as “emergency warmth while hiking” layers. For a cold sleeper/camper, I’d lean slightly heavier.

Best ultralight choices for someone who runs cold

My recommendation for you

Since you specifically said “I get cold easily at camp”, I’d pick:

1. Best overall: La Sportiva — warm for the weight and less likely to leave you shivering when you stop moving.
2. Best premium ultralight: Montbell — if every ounce matters.
3. Best if you want a more “real jacket” feel: Feathered Friends — heavier but more forgiving.

A couple of questions would change the answer:

• What lowest nighttime temperature are you usually camping in (40°F, 30°F, 20°F, below)?
• Are you backpacking (weight matters a lot) or car camping (warmth matters more)?
• Do you prefer a hooded jacket? (For cold camp use, I usually would.)

The absolute lightest high fill-power down puffy jacket on the market is the Montbell Plasma 1000 Down Jacket Go to product viewer dialog for this item. , which weighs a minuscule 4.9 oz to 5.0 oz and uses mind-boggling 1000-fill-power goose down . However, because you get cold easily at camp, an ultra-minimalist jacket like the Plasma 1000 Go to product viewer dialog for this item. (which is hoodless and paper-thin) might not provide enough static warmth once you stop moving around the fire.

The best ultra-light high-fill options that balance extreme lightness, high fill power, and actual camp warmth include:

Montbell Plasma 1000 Down Jacket — 4.9 oz | 1000 Fill Power Go to product viewer dialog for this item. : The ultimate weight-weenie choice. Incredibly warm for its weight, but lacks a hood and features very delicate 7D fabric.

Zpacks Down Jacket — 6.8 oz | 900 Fill Power Go to product viewer dialog for this item. : Exceptionally light with premium 900-fill Muscovy down, includes a warm hood and generous warmth-to-weight ratio for 3-season use.

Mountain Hardwear Ghost Whisperer/2 Hoody — ca. 8.0 oz | 800 Fill Power Go to product viewer dialog for this item. : The iconic ultralight camp staple. It features a snug hood and down-mapped construction, though it is best suited for mild-to-moderate chilly nights rather than deep freeze conditions unless aggressively layered.

REI Co-op Magma 850 Hoodie — ca. 10–12 oz | 850 Fill Power Go to product viewer dialog for this item. : Slightly heavier than the 5-ounce class, but offers significantly more down fill weight and a heat-trapping hood, making it a warmer, more practical choice for people who run cold at camp.

If you want to narrow this down, let me know:

• What temperature range or season you usually camp in
• Whether you prefer having a hood attached
• If you plan to wear it standalone or under a shell

I can help you pick the ideal balance of warmth and weight.

If you get cold easily at camp, I’d prioritize down fill weight + fill power, not just the jacket’s total weight. The absolute lightest puffies often achieve that weight by carrying very little down.

My top picks

Mountain Hardwear Ghost Whisperer UL

$484.99

Feathered Friends Eos

$429.00

Mammut Eiger Nordwand Light Down IN

$449.00

Black Diamond Deploy Down Hooded

$349.30

1. Mountain Hardwear Ghost Whisperer UL — best ultralight choice
The current UL version uses 1000-fill down and extremely light 5D/7D fabric. It's aimed squarely at situations where weight matters. www.cleverhiker.com
Pick this if: you want the lightest practical puffy and will layer it over fleece/base layers.

2. Feathered Friends Eos — my choice if you get cold easily
The Eos weighs about 11.8 oz / 336 g, with 4 oz / 112.5 g of 900+ fill down. That's considerably more insulation than the super-minimal Montbell-style jackets. featheredfriends.com
Why I like it for you: you're giving up a few ounces to get substantially more down, which is a good trade when your problem is actually being cold at camp.

3. Mammut Eiger Nordwand Light — serious warmth/weight
Uses 900-fill down and weighs just over 400 g according to the current listing. It's designed for cold alpine use rather than merely being a casual ultralight jacket.

4. Black Diamond Deploy Down — high-end ultralight
Uses 1000-fill down and is designed specifically around maximizing warmth for very little weight.

One important distinction

The famous Montbell Plasma 1000 is extraordinarily light—around 8 oz for the Alpine Parka—and uses 1000-fill down. www.cleverhiker.com But its very low weight comes partly from having relatively little down. That's fantastic for backpacking, but if you routinely feel cold sitting around camp, I'd rather carry a 11–14 oz jacket with substantially more down.

So my ranking for your specific use case:

If you tell me the coldest nighttime temperature you typically camp in (e.g. 30°F, 20°F, 10°F) and whether you want a hood, I can narrow this down to the lightest jacket that will actually keep you comfortable rather than merely being ultralight.
