Shearling vs down jacket: which is warmer, and when to wear each
Short answer: for the same length, a well-filled down parka is usually warmer than a shearling jacket in dry, deep cold, and much lighter. Shearling wins in wind, in damp cold around 0°C (32°F), and on durability: real sheepskin keeps insulating when it’s slightly damp and lasts for decades, while down loses most of its warmth once it gets wet. So the right choice depends on your climate and how long you’re outdoors, not on which material is “warmer” in general.
This guide compares the two side by side, gives a decision table by temperature in °C and °F, and covers wet weather, wind, weight, care and cost.
Shearling vs down at a glance
| Shearling jacket | Down jacket or parka | |
|---|---|---|
| What insulates | Sheepskin with the wool left on: the wool traps air, the hide is the shell | Clusters of duck or goose down inside a fabric shell |
| Warmth for its weight | Low: heavy for the warmth it gives | Very high: the warmest insulation for its weight |
| Best temperature range (city wear) | About 5°C to −15°C (41°F to 5°F) “feels like” | From mild to extreme cold, depending on fill and length |
| Wind | Very good: the hide itself blocks wind | Depends entirely on the shell fabric |
| Damp and drizzle | Wool still feels warm when slightly damp | Loses loft and warmth when the down gets wet |
| Heavy rain | Not waterproof; suede finishes mark | Not waterproof unless the shell is |
| Packability | Doesn’t pack at all | Compresses into a bag |
| Lifespan | Decades with care | Years; fill loses loft over time, care helps |
| Look | Smart enough for the office and evenings | Casual or technical |
Which is warmer?
It depends on what you compare. Down has the best warmth-to-weight ratio of any common insulation: REI’s expert advice on down vs synthetic lists a “higher warmth-to-weight ratio than synthetic insulation” as down’s main strength, and Switchback Travel (updated 16 April 2026) says “in terms of warmth, nothing can rival down.” A knee-length, hooded down parka also covers far more of your body than a hip-length shearling jacket, which matters more than the material once you’re outside for an hour at −20°C (−4°F).
Shearling fights back in two ways. First, the hide blocks wind, so the warm air in the wool stays put on a gusty street. Second, the wool is much thicker and denser than it looks, so a good sheepskin jacket feels warm the moment you put it on, without the “cold spots” of thin baffles. For walking between home, car, train and office, most people find a heavy shearling jacket as warm as they need down to about −15°C (5°F) “feels like” (see our leather jacket temperature guide for the bands and a wind chill table).
How warm is a down jacket? Read the fill power and the fill weight
Two numbers tell you how warm a down jacket is:
- Fill power measures down quality: how many cubic inches one ounce of down fills in a test cylinder. In REI’s example, “600-fill-power down means that one ounce of that down fills 600 cubic inches of space.” Switchback Travel puts most outdoor jackets at 600 to 900, with some casual jackets at 500 or lower.
- Fill weight is how much down is in the jacket. Switchback’s example: 6 ounces (about 170 g) of 800-fill down is substantially warmer than 3 ounces (85 g) of the same down.
A thin, 500-fill “puffer” with a few ounces of down can be less warm than a good shearling jacket. A long expedition-style parka with heavy, high-fill down will be warmer than any shearling.
Wet weather: shearling’s biggest advantage
Down stops insulating when it gets wet. REI says down tends to “clump up and lose loft when it gets wet, thereby losing its insulating properties,” and IDFL, a down-testing laboratory, puts it more bluntly: wet down “loses close to all of its insulating properties.” Treated or hydrophobic down resists light moisture, but REI notes that in heavy rain “even treated down will get wet,” and Switchback says a water-repellent (DWR) coating on the shell “won’t protect your down jacket during heavy rainfall or prolonged exposure.”
Wool behaves differently. Swedish wool maker Woolpower states that wool can absorb up to about 30% of its own weight in moisture without feeling damp, which is why a shearling collar stays comfortable in drizzle, sleet and the clammy air of a crowded train.
Shearling is still not a raincoat. A suede outside marks in rain, and a soaked fleece takes days to dry. Our guide is shearling waterproof? covers finishes, snow, slush and road salt in detail.
| Weather | Better choice | Why |
|---|---|---|
| Dry cold, −5°C to −15°C (23°F to 5°F) | Either; shearling for city wear | Both are warm; shearling blocks wind and looks smarter |
| Deep cold below −20°C (−4°F), long periods outside | Long down parka | Covers more of the body; more warmth per kilo |
| Damp cold around 0–5°C (32–41°F), drizzle, sleet | Shearling with a smooth (nappa) outside | Wool stays warm when damp; the hide blocks wind |
| Steady rain above freezing | Down parka with a waterproof shell, or a raincoat over layers | Neither insulation likes being soaked; the shell decides it |
| Windy coasts and open plains | Shearling, or down with a windproof shell | Wind strips heat from thin shells |
| Travel, flights, layering under a shell | Down | Packs small and weighs little |
Which suits your climate?
- UK, Ireland, the Netherlands, Belgium, Denmark: winters are damp and usually hover above freezing. A nappa-finish shearling or a shearling-lined leather jacket is the more comfortable everyday choice; down is overkill on most days and suffers in drizzle. Our UK and Northern European winter guide has January averages for eight cities.
- Canada, the northern US, Scandinavia, Finland: both earn their place. Shearling covers the city commute down to about −15°C (5°F); a long down parka covers the deep-cold spells and long hours outside. See our Canadian winter shearling guide.
- Germany, Austria, Switzerland: cold, often dry inland winters suit shearling well for city life; mountains and ski days call for technical down or synthetic layers.
- Japan and South Korea: Tokyo, Osaka and Seoul winters are cold but often dry and sunny; shearling works for city wear, while Hokkaido and northern Korea’s coldest spells favour a long down coat.
- Australia and New Zealand (winter June to August): mild, wet winters in most cities make a smooth-finish shearling or a leather jacket with a warm layer more useful than a heavy down parka.
Weight, comfort and fit
Shearling is heavy. That weight is the insulation, and many wearers like how it sits on the shoulders, but it does not pack, and it can feel too warm on a heated train or in a shop. Down weighs very little, compresses into a bag and suits travel.
Fit matters for both. A shearling jacket should close comfortably over a knit, because the wool doesn’t stretch (our fit guide shows what to check). A down jacket needs room for the down to loft: a tight down jacket squashes the clusters and loses warmth.
Care and lifespan
| Shearling | Down | |
|---|---|---|
| Cleaning | Brush and spot-clean; no machine washing; a sheepskin specialist for a full clean | Many can be washed at home on a gentle cycle following the care label; dry thoroughly so the down doesn’t clump |
| Storage | Wide hanger, breathable cover, cool and dry; protect from moths (storage guide) | Hang or store loose; don’t keep it compressed for months |
| Ageing | Leather softens and develops character; lasts decades | Fill power can drop with use; IDFL notes proper care can return it to close to the original rating |
| Repairs | A leather specialist can re-stitch seams and patch hide | Torn shells leak down; patch kits fix small holes |
Cost and value
A real sheepskin shearling jacket usually costs more up front than a mid-range down jacket, because each one is cut from several whole skins. Over its life, the gap narrows: a well-kept shearling jacket can be worn for decades, while a down jacket’s shell and fill wear out sooner with heavy use. If you buy either, check the label: real sheepskin for shearling (our guide to what shearling is explains how to tell real from faux), and fill power, fill weight and a down-sourcing certification for down.
How to choose: a quick checklist
- Where do you live? Damp, mild cold favours shearling; long spells below −20°C (−4°F) favour a long down parka.
- How long are you outside? Short trips between buildings suit shearling; hours outdoors suit down.
- Is it windy? Shearling, or down with a windproof shell.
- Do you travel or need to pack it? Down.
- Do you need one jacket for work and evenings? Shearling looks right with tailoring and smart-casual outfits.
- Do you want it to last decades? Shearling, with proper care.
Many people in cold countries end up owning both: shearling for the city, down for the deep freeze.
Frequently asked questions
Is shearling warmer than down?
Not weight for weight. Down is the warmest common insulation for its weight, and a long down parka beats a hip-length shearling jacket in deep, dry cold. Shearling is warmer in practice on windy, damp days around freezing, because the hide blocks wind and the wool still insulates when slightly damp.
Is a shearling jacket warm enough for −20°C (−4°F)?
For short periods outside with a hat, gloves and a warm layer, a heavy shearling jacket can manage. For long periods at −20°C or below, a long, hooded down parka is the safer choice.
Is shearling better than down in the rain?
In drizzle and damp cold, yes: wool stays warm when slightly damp, while wet down loses most of its insulation. In steady rain neither is ideal; a waterproof shell is what keeps you dry.
Why is shearling so heavy?
Because the insulation is a whole sheepskin with the wool still attached, not loose clusters of down. The weight is what makes it windproof and durable.
What fill power should a winter down jacket have?
Most outdoor down jackets use 600 to 900 fill power. Higher fill power means more warmth for the weight, but the amount of down (fill weight) and the jacket’s length matter just as much.
Can I wear a down vest under a shearling jacket?
Usually not; there’s little room inside a well-fitted shearling jacket, and it will feel too warm indoors. A thin merino or a light knit is the better layer underneath.
