Built to endure the extremes of high-altitude conditions, the Mountain Hardwear ACI 3 tent is designed with stability and storage in mind to make your next expedition secure, spacious and comfortable.

  • Features

    • Evolution Tension Arch™ features sleeves of strong, nonstretch fabric to reinforce and stabilize the pole structure, maximizing strength while remaining lightweight
    • Sleeved-pole design adds stability, protects poles and makes pitching easier
    • Integrated vestibule provides adjoining gear storage and food prep area outside the main living space
    • 4 adjustable zippered vents (at top center of vestibule, at the rear of the tent and on each side) keep this single-wall tent from getting too muggy
    • The 2 nylon doors in the vestibule can open completely, but also have a full mesh layer, so they can be opened to provide cross-ventilation while keeping out bugs
    • Color-coded poles and webbing at stakeout points ensure easy setup
    • Multiple guyout points with self-equalizing guyout anchors on the side walls
    • 6 mesh pockets for off the floor interior storage
    • Snow port in the floor allows an exit point for accumulated snow
    • Reflective accents add visibility
    • DAC Featherlight™ NSL poles have a high strength-to-weight ratio and use extrusions instead of inserts to avoid breakage; poles are anodized without the use of harmful acids
    • Use an optional footprint to extend the life of the tent floor (footprint not included)
    • All tent materials free of fire-retardant chemicals
    • Comes with high-quality DAC J-stakes
