The right gear can make or break a trekking or climbing experience. Key items include durable hiking boots, layered clothing for changing weather, and a waterproof jacket. A reliable backpack with proper support, sleeping bags, trekking poles, and hydration systems are crucial for long journeys. For climbing, specialized equipment like helmets, harnesses, ropes, crampons, and carabiners are mandatory. Carry a compact first-aid kit, energy snacks, and a portable power bank. Choosing gear that is lightweight yet durable ensures a safe and enjoyable adventure without unnecessary burden.
