When packing for Mount Kilimanjaro’s five distinct climate zones, you must organize your gear into a waterproof duffel bag (75–100L) limited to 15 kg (33 lbs) for the porters, and a 30–35L daypack for your daily personal essentials. Avoid all cotton fabrics in favor of a synthetic or merino wool layering system, which includes moisture-wicking base layers, insulating fleece mid-layers, a heavy down jacket, and hardshell waterproof outer gear. Protect your extremities with rigid, waterproof hiking boots, thick wool socks, windproof gloves, a winter beanie, and a neck gaiter. Finally, ensure your health and safety on the mountain by packing a four-season sleeping bag rated to -10°C, trekking poles, a 3-liter hydration setup (including insulated bottles), a high-quality headlamp with extra batteries, wet wipes, high-SPF sun protection, and a medical kit stocked with blister pads, electrolytes, and altitude sickness medication.
