Built for heavy weather but made of lightweight materials, the four-season Eureka! Mountain Pass tent is made for backcountry adventuring. With a highly breathable, lightweight canopy and zippered, removable side panels, the Mountain Pass is a true three or four season convertible style tent - a home away from home in any season. A waterproof rain fly keeps the tent protected from the elements and creates two vestibules for storing packs, wet boots, cooking gear, and more. High/Low Vent - Air Exchange system allows cooler air in through the low vents and warmer air up and out to reduce moisture inside the tent. Features removable side panels that provide an added layer of protection in changing conditions, plus a gear loft and five pockets for storing essentials. Eureka! found its humble beginnings in 1895 and today their camping gear gives you the freedom to have fun - from tents to cooking systems, and sleeping bags to camp furniture - reliable, easy-to-use, and packed with features campers care about.
