High-Altitude Gear and Apparel List

Here’s a comprehensive gear and apparel list for a high-altitude day hike above 3,500m in Kenya (like Mt. Satima), in cold July weather, with dry but possibly rainy conditions, muddy and marshy terrain, and no overnight stay:

Essentials

• Daypack (20–30L) – Comfortable, with a rain cover.

• Hydration system – 2–3L water (hydration bladder or water bottles).

• Snacks & Food – High-energy, lightweight: nuts, energy bars, fruit, sandwiches.

Clothing (Layered for Altitude & Weather):

Upper Body:

1. Base Layer (Thermal top) – Moisture-wicking (merino wool or synthetic).

3. Outer Layer (Hard shell jacket) – Waterproof, windproof, and breathable.

4. Optional: Lightweight down or synthetic puffy jacket – For summit stops or unexpected cold.

Lower Body:

1. Base Layer (Thermal leggings) – Optional, depending on your cold tolerance.

2. Trekking Pants – Water-resistant or quick-dry fabric.

3. Gaiters – To keep mud and bog water out of boots.

Accessories:

• Beanie or warm hat – Retains body heat at altitude.

• Neck gaiter / Buff – Wind and dust protection.
