Is it better to wear shorts to stay cool?

No. Long, loose-fitting pants provide better sun protection and prevent small scratches from desert scrub. They keep your skin cooler by blocking direct sunlight.

How do I keep water cool in the desert?

Use an insulated bottle sleeve or wrap your water reservoir in a spare fleece inside your pack. Never store water on the outside of your pack where the sun hits it directly.

Packing for Desert Travel

Prioritize loose-fitting, light-colored long sleeves and pants to protect skin from UV radiation and heat. Pack double the water capacity you think you need and utilize a modular layering system to combat the extreme temperature swing between day and night.

Select moisture-wicking, breathable fabrics. Avoid cotton. It holds moisture and stays damp. Choose synthetic blends or Merino wool that pulls sweat away from your skin to keep you cool and prevent chafing.
Implement the desert layering system. Bring a lightweight, windproof jacket or fleece for the night. Desert temperatures can drop by 30-40°F (15-22°C) once the sun sets. A down puffy jacket is essential if you are camping.
Maximize water carrying capacity. Aim for a minimum of 4 liters per person for a full day of hiking. Use a mix of a hydration bladder for frequent sips and hard-sided bottles as a backup to prevent leaks.
Protect your extremities. Pack a wide-brimmed hat with a chin strap for high winds. Include a neck gaiter or 'buff' to protect your face from blowing sand and direct sun.
Sand-proof your electronics. Store cameras, phones, and batteries in double-seal dry bags. Fine desert sand is abrasive and can ruin lens seals and charging ports within hours.
