A Christmas market trip is a different kind of cold. You're not striding between sights, you're standing still holding a mug of something hot, often after dark. Vienna and Prague are both colder than Paris or London in December, with nights around or below freezing.
The plan: one seriously warm coat, worn on the plane, plus thin thermal layers that pack flat. Everything else fits the 40 × 30 × 20 cm free bag.

Source: WMO 1991–2020 climate normals, published by NOAA National Centers for Environmental Information (NCEI accession 0253808). Stations: Wien Hohe Warte (WMO 11035); Praha-Libuš (WMO 11520). Normals are 30-year averages, not a forecast. Sunrise, sunset and daylight are calculated for the 15th of the month in 2026 (local time). °F and inches are converted from the metric figures. “n/a” means the station doesn’t report sunshine in this dataset.
- Around freezing. Average highs are only a few degrees above zero in both cities, and average lows dip below 0 °C.
- Drier than western Europe: Prague is the driest city in this guide, with Vienna in between. Rain or sleet still falls on several days a month.
- About 8 hours of daylight in mid-December, so most market visits happen in the dark, which is when they look best and feel coldest.

What locals actually wear
Everything below is a summary of, or a quote from, the linked source. We don’t make up “local” style tips.
- In Vienna, winter dressing leans traditional and polished: Loden coats, cashmere coats and shearling, with oversized scarves and woollen hats (Vienna's Mühlbauer is a famous milliner).Source [1]: Monocle
- Monocle describes a classic Viennese winter look of a black knee-length coat with tailored trousers.Source [1]: Monocle
- A licensed Prague guide recommends thick-soled, waterproof, lined boots worn with wool socks, because cobbles get wet and cold.Source [2]: Real Prague Guides (licensed Prague guides)
- The same guide's advice: "leave your fashionable but thin wool coats at home". Choose a waterproof, wind-resistant parka that reaches at least to your hips.Source [2]: Real Prague Guides (licensed Prague guides)
- Bring a scarf, a beanie and touchscreen gloves. Prague Castle is windy and St Vitus Cathedral is unheated. Snow is rare, so the cold is mostly damp and windy.Source [2]: Real Prague Guides (licensed Prague guides)
3 outfit formulas
Market evening, maximum warmth
- Insulated, wind-resistant coat or parka (hip length or longer)
- Thermal top and thermal leggings
- Merino jumper
- Jeans or trousers over the leggings
- Lined waterproof boots and wool socks
- Beanie, scarf, touchscreen gloves
Tip: Thermals under jeans add far more warmth than a second jumper, and they pack flat.
Vienna café and museum day
- The coat
- Fine knit or cashmere crewneck
- Tailored dark trousers
- Waterproof boots
- Wool hat and big scarf
Tip: Tailored trousers and a dark coat nod to Vienna's smarter winter style, which matters in grand coffee houses.
Prague Castle hill
- Parka with hood
- Thermal top plus fleece or merino half-zip
- Leggings under trousers
- Thick-soled boots
- Beanie and gloves
Tip: Keep the thermals on for St Vitus. It's unheated, so it doesn't warm you up the way a museum would.
Swatches are a colour guide for each formula, not product photos.

The free-baggage packing list
Your bag: 40 × 30 × 20 cm
Planned for 4–5 nights (both cities), using a soft backpack of about 20–24 litres made to the 40 × 30 × 20 cm size. The rule that makes it work: wear your bulkiest items on the plane. The dotted outline is easyJet’s bigger free bag.
Wear on the plane worn
In the bag 11 items
- A thin fashion coat (the Prague guide says leave it at home)
- Suede boots
- A second pair of boots (wear one good pair)
Liquids: going vs coming home
UK airports vary. Heathrow, Gatwick, Birmingham, Bristol, Edinburgh, Belfast International, Belfast City, Bournemouth, Southend allow containers up to 2 litres; most others, including Manchester, Stansted and Luton, are still 100 ml.
- 2 litresVienna (VIE)
- VariesPrague (PRG), in a 1 L clear bag (100 ml only from T1, which handles UK flights)
Pack your liquids to 100 ml for the whole trip.
Check your room first
Read the hotel, Airbnb or hostel listing, or message the host, and ask whether they provide:
- Iron or steamer
- Hairdryer
- Toiletries: shampoo, shower gel (conditioner often isn’t supplied)
- Towels, plus beach or pool towels
- Washing machine or laundry service
- Plug adapters or USB sockets
- Kettle, tea and coffee
- Slippers and a robe
- A safe
Hostels often don’t provide towels or padlocks.
Every item they provide is one you don’t carry.
No-iron packing
Pick fabrics that don’t crease. Woven cotton and linen crease; knits, merino, jersey and most polyester blends barely do.
- Hang creased clothes in the bathroom while you shower.
- Pack a small crease-release spray under 100 ml (it counts as a liquid).
- Roll clothes, and keep crease-prone pieces in a packing cube on top, not in a vacuum bag.
- Check whether your hotel or Airbnb has an iron.
Buy it there?
Adding a checked bag typically costs around £60–80 return on a budget airline. So if your bag is full, buying bulky or liquid items when you arrive is often cheaper.
Think sun cream, full-size shampoo, insect repellent, a beach towel or flip-flops.
Yes in this destination: Everyday shopping in Prague is generally cheaper than in the UK; Vienna is closer to UK prices.
Tick items off as you pack (your ticks aren’t saved). Liquids rules depend on your departure airport and change from time to time. Check your airport’s current security rules before you decant your toiletries (see liquids rules by airport).
Flying there on Ryanair, easyJet or Wizz?
- Ryanair and Wizz Air under-seat bags are 40 × 30 × 20 cm. A thermal-based capsule fits, but only if you wear the parka and boots on the plane.
- Doing both cities? The bag goes on the train with you, so a backpack is easier than a wheeled case on cobbles.
- easyJet's 45 × 36 × 20 cm free bag lets you add a second warm knit.
Duty-free bag: Ryanair: extra bag allowed · easyJet: extra bag allowed · Wizz Air: extra bag allowed. It still has to fit under the seat or in a locker, and gate staff decide. Duty free and your free baggage →
Sizes come from each airline’s official page (see our free baggage reference for links). Rules change, so check your booking before you fly.
Baggage picks
The ticks compare each bag’s stated outer dimensions with each airline’s free-bag size. A struck-through name means the bag is too big for that airline. Soft bags squash a little; hard cases don’t. We haven’t tested these bags ourselves yet.
