Packing for Extreme Weather Conditions
Layering is the only way to manage extreme temperature swings and harsh conditions. Pack a base layer for moisture management, an insulating middle layer for heat retention, and a windproof/waterproof shell to protect against the elements.
- Build your base layer. Avoid cotton at all costs, as it absorbs moisture and stays cold. Pack 3 pairs of merino wool or synthetic thermal base layers that fit snugly against your skin.
- Select your mid-layer. Bring a high-loft fleece or a packable down jacket. These trap heat effectively while allowing your body to breathe during physical activity.
- Choose your outer shell. Invest in a Gore-Tex or similar technical shell. It must be windproof and waterproof to prevent convective heat loss, which is the primary cause of hypothermia in cold winds.
- Manage your extremities. Pack wool-blend socks (bring 2 pairs more than you think you need), a neck gaiter, a thermal beanie that covers your ears, and glove liners paired with heavy-duty mittens.
- Test your gear before leaving. Spend 2 hours outside in your planned kit during the coldest part of the day at home. If you start shivering, your insulation layers are insufficient.
- Can I use clothes I already have?
- Only if they are technical synthetic or wool layers. Leave all denim, cotton sweaters, and non-technical windbreakers at home.
- How do I keep my electronics from dying?
- Cold kills battery life. Keep phones and camera batteries in an internal pocket closest to your body heat, and pack a small insulated pouch for when they are in use.
