Essential base layers include moisture-wicking synthetic or merino shirts and underwear, paired with convertible hiking pants or shorts for versatility. For variable conditions, mid-layers with fleece, lightweight insulated jackets or vests, and waterproof/breathable rain jackets treated with DWR to repel moisture during the rainy season. Footwear essentials comprise sturdy ankle-support boots with good grip for slippery paths, moisture-wicking socks (wool blend to prevent blisters), and lightweight camp sandals for evenings. Mandatory gear includes adjustable trekking poles for stability on steep inclines, a 30-40L daypack with rain cover and hydration bladder (2-3L capacity), a compact first-aid kit containing blister treatments, altitude medication, and DEET-based insect repellent, plus a multi-tool knife, headlamp with spare batteries, and portable water filter for streams.
