Tent
The main part of a Eureka tent is, of course, the tent itself. This consists of a "bathtub" floor, which is heavy-duty, tarp-like material, waterproof sides and a roof, which is either bug-proof mesh or light, breathable material. A minimal tent is made up of one "room" with a single door. However, larger tents for groups or families may have several entrances, windows and internal dividers making up additional rooms.
Fly
The fly of a tent is an essential component. While parts of tents are always waterproofed, typically an entire tent is not, which allows for air to flow through the tent. The fly, or rain fly, is the waterproof roof of a tent. It is generally attached to the outside of the tent with several bungee cords that fasten to the tent poles or to the tent pegs. This keeps the rain fly secure, even in extreme weather. The fly may have its own pole to keep it raised off the tent so air can keep circulating. Another advantage of having a detachable rain fly is that you can leave it off when the weather is warm and clear.
Poles and Pegs
Most Eureka tents feature light, flexible and collapsible fiberglass poles. These break down and hold together thanks to elastic bands that run through the center of each pole. This enables the poles to be light, easy to store and carry, and easy to set up. The poles thread through sleeves built into the tent or through individual straps and are erected to hold the tent up. The poles are then secured in reinforced pockets at the edges of the tent. Other, larger Eureka tents have aluminum poles. These are larger, heavier-duty tents. They are generally not designed for backpack camping, as the poles are larger and heavier, and hold up a larger and heavier tent. These poles snap together to form larger poles that make up the tent's supports. Tent pegs are typically small L-shaped pieces of aluminum that secure a tent to the ground, but they may also be large plastic "nails" that serve the same purpose.
