How to pack for winter travel: the layering system and ski gear guide

Layer 1

Base layer — moisture-wicking thermals

Merino wool or synthetic thermal underwear. This is the essential winter travel piece — lightweight, compresses small, works for hiking, skiing, and city walking. Bring 2–3 base layer tops and 1–2 bottoms. Brands: Smartwool, Icebreaker (merino wool); Patagonia Capilene (synthetic).

Layer 2

Mid layer — insulating puffy

A down or synthetic puffy jacket traps warmth and compresses extremely small. A fleece jacket works for milder cold. The Uniqlo Ultra Light Down jacket compresses to the size of a water bottle and is comfortable down to 30°F with a base layer underneath.

Layer 3

Outer layer (shell) — wear on the plane

A waterproof, windproof shell jacket with no insulation — like an Arc'teryx Alpha or a quality rain jacket — protects against wind and snow without the bulk of an insulated parka. Wear this on the plane instead of packing it.

At the security checkpoint

Boots stay on through security unless they have substantial metal components — in that case remove them at the checkpoint like you would any other footwear. The jacket goes into a bin; pick it up on the other side and put it in the overhead bin at the gate.

Clothing

• 2 base layer tops + 1 base layer bottom
• 1 mid-layer puffy (compressed in bag)
• 1 outer shell (worn on plane)
• 2–3 t-shirts or light tops (to layer under base)
• 2 pairs of pants (jeans or hiking pants — 1 worn on plane)
• 1 pair of thermal leggings (doubles as pajamas and under-layer)
• 5 pairs of wool socks — wool is warmer and drier than cotton
• 5 pairs of underwear

Accessories

• 1 warm hat (compresses flat)
• 1 pair of gloves (compresses flat)
• 1 scarf or buff (wrap style, compresses to almost nothing)

Shoes

• 1 pair of winter boots (worn on plane)
• 1 pair of lighter shoes or sneakers (packed)

Ski boots

The hardest item — heavy, rigid, enormous. Three options:

• Rent at the resort: $30–60/day for boots. Most quality resorts have excellent rental boot fitting — the most efficient option for occasional skiers.
• Ship via FedEx or UPS: Ship ski boots ahead in a padded bag (~$40–60 each way, 2–3 day transit). Often cheaper than airline ski bag fees.
• Check as airline ski bag: Airlines charge $35–75 each way for ski boot bags. Most airlines count ski boots + poles as a single checked bag.

Skis and snowboard

Rent at the resort unless you have a custom setup.

• Rental quality at major ski resorts (Vail, Park City, Breckenridge, Aspen) is genuinely high — demo equipment is available that surpasses mid-range consumer skis.
• If bringing your own: airline ski bag fees are typically $35–75 each way. Delta and Southwest include ski bag in checked bag allowance on select routes to ski destinations.

Ski clothing — packs better than you think

A ski jacket in a compression sack reduces to the size of a football. Ski bibs compress to roughly the size of a large fleece. Both items can fit in a 40L carry-on alongside a week of base layers and accessories.
