With new architecture that adds floor space and more head and shoulder room, the 2020 REI Co-op Half Dome 3 Plus tent gives you plenty of room to stretch out—or even bring your favorite camp dog.


  • Hubbed, color-coded pole assembly simplifies setup
  • Mesh panels in upper portion of tent improve ventilation and views; ripstop panels in lower portion provide privacy, reduce drafts and exposure to blowing dust or dirt
  • Fly design allows sides and ends to be rolled up to maximize views and airflow; everything also rolls down quickly if a storm blows in
  • Fly has 4 ceiling vents that provide airflow to prevent condensation buildup
  • REI Exclusive tension-truss architecture creates stable vertical sidewalls for generous space and plenty of headroom
  • 2 large doors and 2 vestibules offer easy access and additional covered storage
  • When zipped open, doors stash out of the way in pockets just inside the door opening
  • Pockets and hang loops help organize the interior
  • Includes guylines with tighteners, pole-repair tube, pole bag, 8 stakes and stake bag
  • Made with solution-dyed mesh to reduce water and energy use in manufacturing
  • REI Half Dome 3 Plus footprint sold separately
  • Uses 2020 Half Dome tent design
  • 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
