If you want to stay dry on your next trip and avoid the hassle of faulty zippers, ALPS Mountaineering is right there with you. Their Vertex tents are designed around one continuous hubbed pole, which makes for a free standing tent that is enhanced with 2 doors for easy entry and 2 vestibules for gear storage and extra weather protection. Extra large #8 zippers make opening and closing the doors and vestibules a breeze. The Vertex has aircraft alloy aluminum poles that are strong and lightweight. Assembly is really easy, with tent clips that just snap in place over the poles. The top of the tent has a spreader section for increased head room. With a factory sealed fly and floor seams, you're sure to stay dry in rainy weather. The polyester fly and floor are urethane coated, factory sealed seams for maximum weatherproofness. The fly buckles to the tent, offering a much more secure attachment when compared to elastic cord. The mesh roof vents increase ventilation and improves star gazing. All of these features combined with 64 square feet of interior space makes the Vertex 4 a great choice for any camping trip.
