The three-layer rule
| Layer | Job | What to pack |
|---|---|---|
| Base | Warmth, wicking sweat | Thermal tops and leggings, 2–3 sets |
| Mid | Trapping heat | Sweater, fleece or a light down vest |
| Outer | Blocking wind and wet | Windproof down jacket or waterproof coat |
Trains, shops and restaurants are often very warm, so easy to take off beats thick. Your head, hands and neck lose heat fastest — a scarf, gloves and beanie often help more than another sweater.
Cold-weather items people overlook
- Non-slip shoes — deep tread matters more than height.
- Moisturiser — cold air plus indoor heating dries skin and lips fast.
- Battery life — cold drains phones and cameras quickly; keep your power bank in an inner pocket.
- Heat packs — stick-on packs on your lower back work best (never directly on skin).
- Sunglasses — snow glare is intense, especially for skiing.
Packing tips for bulky winter clothes
Wear your down jacket and heaviest shoes on the plane, and use compression bags for the rest. Planning to shop? Leave room or pack a foldable bag for the way home.

FAQ
How many coats should I pack for a winter trip?
One good windproof coat is enough. Layer a thermal base, a fleece or sweater and the coat on top. Indoor heating is usually strong, so being able to take layers off matters more than one very thick jacket.
Can I take hand warmers on a plane?
Disposable air-activated (iron powder) hand warmers are generally allowed in both carry-on and checked bags. Rechargeable hand warmers contain lithium batteries and follow power bank rules — carry-on only.
Do I need snow boots?
Not necessarily, but you do need non-slip soles and ideally waterproof uppers. Icy city pavements are more dangerous than deep snow. Slip-on ice cleats are a cheap, light extra.
