Our Quarter Dome T3 tent uses an innovative new design to create a strong, ultralight tent with generous interior volume and an easy setup


  • This tent for three weighs in at only 4 lbs. 11 oz. and its rectangular floor plan with area-wide headroom offers flexibility in space usage
  • Tension Truss architecture creates superior structural integrity and generous head room
  • Dry entry/exit vestibule design ensures water won't drip into the tent when doors are open during rainy weather
  • Preassembled hub/pole set, pole clips and color-coding ensure a quick and easy setup; poles break down small to fit easily in your backpack
  • DAC Featherlite® NSL poles help make this tent ultra light
  • Seam-sealed bathtub design and water-tight corners create a waterproof floor
  • Active climate control uses flow-through chimney ventilation to keep air moving through the tent to reduce condensation; vents operate from inside
  • No-wick construction ensures that water won't sneak through susceptible areas such as guy-out points, polewraps and zippers in wet conditions
  • Abundant pockets keep your tent tidy; doors cleanly stash away in their own pockets
  • Attention to detail shows in the reflective guy points and adjustable cleat-lock tie-downs on the rainfly
  • Save weight and create a minimalist shelter by using just the rainfly, footprint (sold separately) and poles
  • Comes with guylines and tighteners, stakes, pole repair tube, pole and stake bags and tapered, easy-to-stuff compression stuff sack
  • Average minimum weight specification is based on tent, rainfly and poles only
  • REI is Climate Neutral Certified; as we work to actively reduce our footprint, we measure annual carbon emissions and purchase an equivalent amount of verified carbon credits
