Fjällräven might be best known for its Swedish heritage, iconic Kånken packs, and classic G-1000 trekking trousers, but the brand has steadily carved out a serious reputation among cold-weather adventurers too. Their Keb walking trousers have long been one of our go-to options for serious hillwalking, while the Abisko Lite 1 — which features on our list of the best 4-season tents — is a trusted companion for solo missions into the wild. Known for hard-wearing, long-lasting kit made with an emphasis on sustainability, Fjällräven consistently punch above their weight in the field.
The Expedition Pack Down Hoody continues this trend — a midweight down jacket designed for everything from local hikes and breezy dog walks to wild camping trips and mountain scrambles in dry, cold conditions. Weighing in at 506 g (measured on our own scales) and packing down into its chest pocket to a neat 27 x 15 x 8 cm bundle, it is a jacket you can genuinely forget about until you need it. RRP is £315, but it is often found for far less — currently just £214.20 at LD Mountain Centre — and for that, you are getting an ethical and versatile down jacket with a serious pedigree.
It sits price-wise below premium ultralight options like the Arc’teryx Cerium Hoody (£350) and the Mountain Hardwear Ghost Whisperer UL (£310), both of which are lighter (338 g and 240 g respectively) and use higher fill-power down (850 and 800 respectively). That said, it is considerably lighter and more packable than the Mountain Equipment Lightline, our long-time cold-weather favourite, which weighs 776 g and offers more warmth but far less versatility. The Fjällräven sits comfortably in the middle of this pack — not the lightest, not the warmest, but perhaps the best all-rounder for UK-based adventures where sub-zero temperatures and high alpine exposure are not the norm.

We tested the Fjällräven Expedition Pack Down Hoody across three very different wild camping trips — each one throwing up a different set of challenges and conditions that made for a solid real-world test of how this jacket holds up in the UK.
The first outing saw us heading up Moel Siabod on a crisp but calm day, with clear skies and the kind of still air that makes you think spring might be arriving early. We had it stashed at the bottom of the pack all day, stuffed into its own pocket and barely taking up any space. When the sun dropped behind the mountains and the temperature slipped to around 4°C, we pulled it on over a T-shirt and midlayer and were perfectly warm sitting outside the tent, watching the sky fade.
Trip two was much the same — a summit camp, this time on a sun-kissed evening, with a gentle breeze and night-time lows hovering around 8°C. Here, we wore the jacket with just a T-shirt underneath while setting up camp and cooking dinner. It was breathable enough to stay on while we moved around, and warm enough to take the edge off once we stopped. It is exactly the kind of layering piece you want for high camps in the shoulder seasons.

But the real test came on Pumlumon Fawr in the Cambrian Mountains. The weather turned rough that night — high winds, sideways rain and a general sense that we might have pushed things a bit far for a single-night adventure. It was the kind of night where everything gets damp, from your socks to your spirits. The hoody got properly soaked as we made camp in gusty, exposed conditions, but with the hood cinched and the collar zipped up high over our faces, it still offered decent protection. Once inside the tent, it dried quickly — far faster than we had expected. That performance alone gave us confidence in its reliability when things go sideways in the hills.
On each of these trips, the jacket came into its own in the quiet moments — the morning brew, the post-dinner sit-down, the dawn packing session before a descent. It never felt like too much jacket to bring, never got in the way, and always delivered just the right amount of warmth for the conditions we faced.
The first thing we noticed was how neatly the Expedition Pack Down Hoody packs away. At just over 500 g and stowing into its own chest pocket, it compresses to about the size of a SmartWater bottle. When you are loading up for a night in the hills, every bit of space counts — and this jacket quietly earned its place in the pack on every trip we took, whether it was up Moel Siabod or across the slopes of Pumlumon Fawr.
Once unpacked, it is clear this is a piece made for movement. The regular fit leaves enough room for a T-shirt and midlayer underneath without ever feeling bulky, and the hem drops well over the hips — crucial when you are crouched on wet grass cooking dinner or sat in a breeze watching the weather roll in. The adjustable drawcord lets you seal in warmth when the temperature drops, and the overall cut just works. No awkward bunching, no cold spots, no faff.

“It never felt like too much jacket to bring, never got in the way, and always delivered just the right amount of warmth for the conditions we faced.”
Warmth-wise, the 700-fill-power down feels like a sweet spot for British use. It is not a big, marshmallowy belay jacket like the Mountain Equipment Lightline, but it is warm enough with a couple of layers underneath — especially when you are on the move. We wore it comfortably around camp in 3–8°C conditions, and it performed just right: cosy without overheating, trim without underdelivering.
You do need to respect its limits. The outer shell is not waterproof — it will see off a quick shower, but you will want a proper shell layer if the heavens open. That said, during one very soggy night in the Cambrian Mountains, we were impressed by how quickly it dried out inside the tent. It is not pretending to be a rain jacket, but its fast-drying nature gives it a real edge when you are caught out by surprise.

Around the head and hands, the details hold up. The two handwarmer pockets are deep enough for gloves, snacks or a power bank, and the fleece-lined hood is a proper asset. It cinches neatly with a rear cord and the high collar comes right up over your mouth, helping to block out the chill on exposed ridgelines. Combined, these features make it a genuinely pleasant place to hunker down when the wind picks up.
The outer and lining fabrics are 100% recycled polyamide, and the down is fully traceable and ethically sourced. That matters to us, and it should matter to anyone investing in long-term kit. As with other Fjällräven gear we have tested — from the Keb trousers to the Abisko Lite 1 — this jacket feels built not just to last, but to be a piece of kit you will actually want to keep reaching for, season after season.

Our verdictA phenomenal bit of kit for the realities of UK use.The Fjällräven Expedition Pack Down Hoody is a brilliant companion for shoulder-season camping and hiking. It is not the warmest jacket we own — the Mountain Equipment Lightline beats it hands down when the mercury dips — but it is lighter, more packable, and far more versatile as a midlayer or standalone piece.It kept us comfortable at 3–4°C with just a base and midlayer, blocked wind effectively with the collar and hood cinched, and dried fast after a drenching. It never felt bulky or like overkill — just dependable warmth right when you need it.What really stands out is how well it fits the realities of UK use. It is not a technical alpine piece — it is made for the kind of conditions we actually get. Showers, squalls, chilly evenings, muddy trails, still mornings. Weather that changes fast, and trips where you need kit that is light enough to carry but warm enough to pull on the moment you stop moving. In that sense, it is pretty much spot on.Buy the Fjällräven Expedition Pack Down Hoody →

What activities is the Fjällräven Expedition Pack Down Hoody suitable for?An excellent jacket for a wide range of UK activities — from wild camping and hillwalking to cold-weather hiking, travel and everyday winter use. Works well as a midlayer under a shell or as a standalone piece in cold, dry conditions. Not ideal for technical alpine climbs, but perfect for the terrain and weather we typically get in the British hills.
How warm is the Fjällräven Expedition Pack Down Hoody in real-world conditions?Warm enough for British shoulder-season use. Performed well in temperatures from 3–8°C with only light layers underneath, though noticeably less warm than the Mountain Equipment Lightline in similar conditions. Think of it as a dependable midlayer or mild-weather outer.
Is the Fjällräven Expedition Pack Down Hoody easy to carry in a backpack?Yes. It packs into its own chest pocket and measures roughly 27 x 15 x 8 cm. At just over 500 g, it is compact and light enough for multi-day hikes or wild camping trips where space and weight matter.
How waterproof is the Fjällräven Expedition Pack Down Hoody?It is not waterproof. It can handle light showers and drizzle thanks to its DWR-treated outer fabric, but you will need a proper shell in sustained rain. It dries quickly once wet — a meaningful advantage when caught out in changeable British weather.
