Cold Weather
Hokkaido powder, Patagonian wind, Icelandic sideways rain — the three-layer system, decoded.
Cold weather packing fails for one of two reasons: people pack a single very warm layer that they wear all the time and overheat in, or they pack five mediocre layers that do not work together. The fix is the same fix Alpine guides have used for fifty years — a small, deliberate three-layer system in which each piece has one job. Get the system right and the same kit works for a powder week in Niseko, a windy hike at Torres del Paine, and a wet weekend in the Westfjords.

The Three-Layer System
The system is base, mid, and shell. The baselayer sits against the skin and moves moisture away from it. The mid-layer traps warm air. The shell blocks wind and rain. Each one is light on its own, and the combination handles a startling range of conditions: shell alone for a wet, mild Tokyo winter day; base plus shell for moving fast in cool weather; all three for a still, cold morning at minus five. The reason the system works is that you can shed and add pieces as the weather and your effort change — the alternative, a single very warm jacket, leaves you sweating on the climb and freezing at the lookout.
Down vs. Synthetic
The mid-layer choice is between down and synthetic insulation, and the rule is climate. Down is warmer per gram, packs smaller, and lasts longer — but it loses almost all of its insulating value when wet, and is slow to dry. Synthetic is bulkier and heavier, but insulates damp and dries overnight. For dry cold — Hokkaido in February, the Andes in winter, continental Europe in January — down is the right answer. For wet cold — Iceland, Patagonia, the Scottish Highlands, the Pacific Northwest — synthetic is.
The hybrid answer that works for most travellers is a light down jacket (around 800 fill, 250-300g total weight) under a hard-shell rain jacket. The shell keeps the down dry; the down does the warming. Two pieces, every climate, fits in a packing cube.
Baselayer Fabrics
Cotton long underwear is the wrong answer. It holds sweat, freezes, and is responsible for most cold-weather misery. The two right answers are merino wool and synthetic.
- Merino (200gsm for cold): warm, doesn’t stink after three days of wear, comfortable next to skin. Slower to dry than synthetic and more expensive. The civilised choice for travel where you wear the layer in town and on the trail.
- Synthetic (polyester, polypropylene): dries fast, cheap, very durable. Smells terrible after one hard day. The right choice for active trips with regular laundry access.
- Silk: a niche option — very thin, very warm for the weight, packs to nothing. Good as a sleep layer or under jeans for a city trip in a cold-but-not-extreme climate.
Gloves That Work With Phones
The two-glove system has become the default. A thin liner glove (merino or fleece, with conductive fingertips for phones) handles most situations — train rides, walking around Sapporo, taking photos at minus three. A heavier waterproof outer mitten or glove goes over the liner when the weather actually bites. The mistake is one big ski glove that comes off every time you want to use your phone, which means you take it off twenty times a day and your hands stay cold.
Traction
Icy sidewalks are the most dangerous thing about a winter city trip. A pair of slip-on traction devices — Yaktrax, Kahtoola Microspikes, or the Japanese-market equivalents — weighs almost nothing and converts ordinary walking shoes into something that will not put you on your back outside Sapporo Station. They go over the shoes you already brought. Microspikes are the right tool for actual ice; Yaktrax-style coils handle packed snow and the polished stone of European old towns.
Drying Gear in Damp Guesthouses
Cold-climate guesthouses, ryokan, and refugios are often poorly heated and slow to dry wet gear. A few small habits help. Hang shells inside out, with the inner liner exposed to the air. Stuff damp boots with newspaper (the front desk usually has some) overnight; it pulls moisture out far faster than air alone. Bring a few clothespins and three metres of paracord for an instant clothesline above a radiator. And carry a small microfibre towel — the chamois kind — to wring out a wet baselayer before hanging it; a single pre-wring cuts drying time in half.
Cold-weather packing is the inverse of tropical packing. Where the tropics reward minimalism, the cold rewards system — a small number of pieces that work together precisely. Get the system right once and it travels with you for years.
