The Eureka Timerberline four person tent is built to last for years with a floor, walls, and fly made of 1.9 oz standard taffeta nylon. The large windows are made of 40denier NoSeeUm netting, providing optimal ventilation. The 1/2 aluminum five pole A-frame is lightweight, but still strong that makes it simple to set up the tent. It also has a door on the side that allows for easy entrance and exit , and you can open the door and window independently of one another with the twin track zippers. It also has two mesh pockets on the inside and two attachments for gear lofts and clotheslines.
