Summary
The unanimous #1 pick across every major backpacking tent roundup. At just 3 lbs with two doors, two vestibules, and 29 sq ft of floor space, it defines what a modern ultralight tent should be.
The rare tent that actually fits its advertised capacity — three adults sleep side by side without sharing pad space. Includes a footprint and uses thicker fabrics than most competitors.
Pros
- Only 3 lbs packed weight — can be stripped to ~2.5 lbs by leaving stakes and stuff sack
- Two doors and two vestibules for a true two-person setup
- Pre-bent poles and steep walls maximize headroom for its weight class
- Color-coded grommets and substantial zippers make setup intuitive
- Tested in Patagonia, Mongolia, East Africa — proven in real conditions
- 43.7 sq ft interior — genuinely fits three adults without head-to-toe sleeping
- Includes footprint — saves money and speeds up setup
- 75D polyester taffeta floor and body for above-average durability
- Wide-mouth stuff sack is one of the easiest to pack of any tent tested
- Two doors and two vestibules for gear storage
Cons
- $600 price tag is steep — one of the pricier options in its class
- 15-20D fabrics are thin and require careful use on rough ground
- Interior is snug for two people on longer trips
- 7.1 lbs — must split weight across the group
- Below-average space-to-weight ratio compared to ultralight alternatives
- Average weather resistance in severe storms
- Bulky packed size
Our take
If you backpack more than a few times a year, just buy the Copper Spur UL2. It's been the top pick for years across Outdoor Gear Lab, Switchback Travel, and the backpacking community — that kind of consensus doesn't happen by accident.
Every backpacking group of three eventually argues about tent space. The Half Dome 3 ends that argument — it's the only 3-person tent we've seen that genuinely fits three people without someone sleeping diagonally.
