  • Features

    • Citing this Editors' Choice winner, the April 2011 Backpacker asked, "Where are the smoke and mirrors? This family-size tent weighs the same as some 2-person shelters"
    • 2 large doors each with a vestibule provide easy access and gear storage
    • Hub/pole design with H-Clip connectors attach tent body to cross pole and DAC Twist Clips attach tent body to pole frame; both contribute to a quick and easy setup
    • Light yet strong, DAC Featherlite® NSL poles with press-fit connectors and lightweight hubs are anodized without the use of harmful acids
    • Mesh body and roof vent offers excellent ventilation to keep condensation from building up
    • Rainfly is made from ultralight silicone-treated, ripstop nylon with a waterproof polyurethane coating
    • Lightweight fabric has a high thread count and double twisted thread for strength and durability
    • All seams taped with waterproof, solvent-free polyurethane tape (no PVC or VOCs)
    • Interior mesh pockets keep your gear organized and up off the tent floor; gear loft loops allow you to add your own gear loft, not included
    • Reflective guyline and reflective webbing on tent corners enhance nighttime visibility
    • Includes stuff sacks, stakes and guyline/tighteners
    • For a lightweight setup during nice weather, leave tent body behind; use footprint (sold separately) with poles, fly and stakes
    • Average minimum weight specification is based on tent, rainfly and poles only
