Included in the Glacier are the oversized #10 door and vestibule zippers and heavy duty polyester oxford floor. The #10 door zippers will give you a lifetime of smooth operation and the oxford floor, which is about twice the weight of normal nylon floor material, will greatly increase the durability of your tent.

The full coverage 75D 210T Polyester fly buckles on for extra strength and adjustability and will protect you from the elements, even under the nastiest conditions. A large vestibule with double zippers makes a great storage area. The fly and floor seams are factory sealed to give you the best weather protection.
