A week in the Alps means living in two climates at once: the dry, over-warm air of a hotel room or a crowded gondola, and the sharp, bright cold of a ridge at 2,500 metres. Most packing mistakes come from preparing for only one of them. Pack as though every day involves a warm start, a cold middle and a wet finish, and the week mostly takes care of itself.

What follows is a workable checklist rather than a gear catalogue. You do not need much. But what you do bring should be reliable, and a few things should exist twice.

Start with the layers, not the jacket

The jacket is the least interesting piece of clothing in your bag. It sits on top of a system, and the system is what keeps you warm. Get the three layers right and a mid-range shell will outperform an expensive one worn over a cotton T-shirt.

Base layer

Merino wool or a synthetic blend, close to the skin, long sleeves. Leave cotton at home — it holds sweat against your body and turns cold the moment you stop moving. Two or three base layers cover a week if you rinse them in the evening; they dry overnight in a warm room.

Mid layer

Bring two. A thin fleece for skiing, and a warmer synthetic or down jacket for standing around, chairlifts and the walk back from the lifts. That warmer jacket is the one item worth spending on, because you will wear it every evening.

Outer layer

A waterproof, windproof shell with taped seams, a hood that fits over a helmet and pit zips for the climb out of the village. Ski trousers with a sensible waterproof rating — or bibs if you feel the cold or spend time sitting on snow. One pair is enough for a week of resort skiing.

Pack two of anything you wear on your hands or feet

Cold hands end more ski days early than bad technique. The fix is rarely a more expensive glove. It is a second pair.

• Gloves: one warm insulated pair, one thinner pair for milder days, plus thin liner gloves so you can open a lift pass pocket or check a phone without exposing skin. If your hands run cold, mittens beat gloves every time.
• Socks: three or four pairs of thin ski socks in wool or synthetic. Thick socks do not make boots warmer; they make them tight, slow the circulation and leave your feet colder than before.
• Neck and head: two merino buffs and a warm hat. A buff doubles as an ear warmer and a face covering on windy lifts. Add a helmet liner if you wear a helmet.
• Spares that matter: a second hat and a second pair of thin gloves, because one set will end up damp in a pocket by Wednesday.

The daypack, item by item

You will carry the same bag every day, so keep it small and pack it the same way each morning. Fifteen to twenty litres is plenty. Anything bigger becomes a temptation to carry things you never use.

1. Water bottle or a small thermos. Cold air dehydrates you quietly; a litre for a ski day is a reasonable start.
2. Food that survives being squashed: nuts, dried fruit, chocolate, a sandwich taken from the breakfast buffet.
3. High-factor sun cream and an SPF lip balm. Snow reflects sun from below, and altitude makes it stronger than you expect.
4. Sunglasses with a category 3 or 4 lens, and goggles. Both, every day — goggles fog, glasses get lost.
5. A spare thin pair of gloves and a spare buff.
6. Power bank and cable. Cold drains phone batteries fast, and your lift pass, map and camera may all live there.
7. Blister plasters, a little tape and two painkillers. Tiny items, trip-ruining when missing.
8. A zip bag for the phone, and a small headlamp if there is any chance of finishing late.
9. Cash in small notes and coins. Not every mountain hut, bus or village bakery takes cards.
10. A card with your accommodation address and an emergency contact number, written down.

Boots, village shoes and the evenings

If you are renting ski boots, arrive early enough to have the fit checked properly and bring the thin socks you will actually ski in. If you are bringing your own, bring only boots you have already skied in comfortably — a week is a bad time to break in new ones.

For everything off the snow, pack waterproof boots with a grippy sole. Alpine villages are icy in the morning and slushy by four in the afternoon, and trainers on packed snow are an accident waiting to happen. Add hotel slippers, swimwear if your hotel has a pool or sauna, one relaxed outfit for dinner, and a couple of pairs of wool socks for the room.

Documents, insurance and money

Check that your travel insurance explicitly covers winter sports. Many standard policies exclude skiing, and off-piste skiing usually needs an add-on. Carry the policy number and the emergency assistance line on paper as well as in your phone. Read the wording, and if you are unsure what a policy actually pays for, ask the insurer before you travel rather than after.

Assume your phone will be cold, flat or out of signal on the day you need it most. Paper weighs nothing.

• Passport or ID card, plus photocopies kept somewhere separate.
• Any entry document or visa required for the country you are visiting.
• Printed lift pass voucher, accommodation and transfer confirmations.
• Insurance policy and the emergency number.
• Your health or insurance card for the country you are visiting, if you have one.
• Two payment cards kept in different bags, and some local cash. Italy, France and Austria use the euro; Switzerland uses francs, and some Swiss huts and buses still prefer cash.

Pack for the journey as well as the mountain

Travel days are where good packing quietly pays off. Put one full change of clothes and your base layers in your carry-on, so a delayed bag does not cost you the first morning on the hill. Wear your bulkiest items on the plane or in the transfer minibus, and check the baggage allowance before you start rolling things up — charter flights and shared transfers are often stricter than they look.

Roll soft items rather than folding them, use a couple of packing cubes to keep base layers apart from everything else, and take a small bottle of washing liquid. Merino can be worn two or three times if it is aired properly between outings, which is usually enough to halve what you need to bring.

The night before you leave

Lay everything out on the bed and pack in the same order: layers first, then boots and shoes, then the daypack, then documents on top where you can reach them. Charge the power bank, download offline maps, screenshot the lift opening times, and put the spare gloves in your jacket pocket now rather than remembering at 8am. Check the forecast once and add a single extra layer if the week looks colder than expected.

Then close the bag and stop. A week in the Alps is more enjoyable when the packing was slightly boring, done early, and finished the night before.
