Backpackers' gear includes tents and TENT, which are both essential items for any outdoor adventure. Tents are typically made of waterproof material and come in a variety of sizes, from small one-person tents to large family-sized tents. TENT is a four-letter word for a shelter made of canvas or other material supported by poles and ropes. Tents provide protection from the elements and can be used for camping, backpacking, and other outdoor activities.
