How to pack for an Arctic winter
Dress in three distinct layers: a moisture-wicking base, an insulating mid-layer, and a windproof, waterproof outer shell. Never pack cotton, as it traps moisture and leads to rapid heat loss in sub-zero temperatures.
- Select your base layer. Pack thermal tops and bottoms made of 100% merino wool or high-quality synthetic blends. Avoid cotton entirely, as it stays wet once you sweat. Bring 3 sets for a week-long trip.
- Choose your insulation. Bring a thick wool sweater or a heavy fleece for your middle layer. For extreme cold, add a lightweight down or synthetic 'puffy' jacket that can be worn under your main winter coat.
- Prioritize your outer shell. Your outermost layer must be windproof and waterproof. Look for a parka with a high fill power (at least 700) and a hood lined with synthetic fur, which helps break the wind before it hits your face.
- Protect your extremities. Pack two pairs of heavy wool socks for every day—one to wear and one to dry. Bring mittens rather than gloves, as keeping your fingers together generates significantly more body heat.
- Can I just wear one very thick coat?
- No. Layering is essential because you will overheat if you are active (like hiking or dog sledding). You need to be able to peel off layers to stay dry.
- How do I keep my camera batteries from dying?
- Keep spare batteries in an inside pocket close to your body heat. Cold weather drains lithium-ion batteries in minutes if they are exposed.
