How to Pack Clothing for High-Altitude Family Travel
Dress your family in three distinct layers: a moisture-wicking base, an insulating middle, and a windproof/waterproof outer shell. Prioritize wool or synthetic materials over cotton, and always pack an extra set of thermal layers for every family member regardless of the season.
- Select the base layer. Avoid cotton entirely; it traps moisture against the skin and causes rapid heat loss. Choose merino wool or polyester thermal tops and bottoms. Pack two sets per person so one can be washed/dried while the other is in use.
- Prepare the insulation layer. Bring a mid-weight fleece or a lightweight down jacket. These trap body heat effectively. For children, a synthetic-fill jacket is often better than down because it stays warm even if it gets damp from snow or spills.
- Add a weather-resistant shell. Pack a windproof, waterproof jacket. High altitudes are significantly windier than sea-level locations. This shell protects against sudden mountain squalls and traps the heat generated by your mid-layer.
- Don't forget the extremities. Pack wool socks, beanies that cover the ears, and gloves for everyone. At altitudes above 8,000 feet, the sun is stronger; pack polarized sunglasses and UV-rated lip balm, as these are technically 'clothing' for your eyes and skin.
- Why is cotton bad for high altitudes?
- Cotton loses its insulating properties once it gets wet from sweat or rain, which can lead to hypothermia even in mild temperatures at high elevations.
- Do we really need sunglasses?
- Yes. UV radiation is 4-5% stronger for every 1,000 feet of elevation gain. Snow blindness and retinal damage are real risks for children and adults.
