Pros: Double doors/vestibules; Small and lightweight; Stuff sack has compression straps
Cons: Minimal ventilation when fly is fully closed; More finicky to set up than other single-wall tents; Being a single wall, condensation forms on interior of tent
Bottom Line: Though it has its flaws, the REI Ace SW2 is a great single-wall tent that equally balances single-wall cons with backpacking pros.

It’s a challenge to create a single-wall tent that balances adequate ventilation with lightweight design and ample features to keep both minimalists and car campers happy, but REI pulled it off with its freestanding, three-season Ace SW 2.
The appeal of a single-wall tent versus a double-wall tent is it doesn’t have a rain fly. That generally means less weight and less bulk, so you can stow it in a smaller pack and cut weight from your trip.
The Ace SW 2, which has a door and vestibule on either side of the rectangular-shaped tent, weighs just less than four pounds.
The double-door design is ideal when you and your camping partner are both scrambling to get out of the rain, and the large vestibules (both of which are 6.6 square feet) allow you to take off shoes or organize gear while staying out of the elements.
The tent, which has been on the market since this spring, doesn’t have any zip-down windows.
Instead, the vestibule is the only layer protecting you from the elements on the sides as the inside layer of the tent is mesh. The ends of the tent are made from the same coated nylon as the rest of the Ace.

The mesh-window interior is a great feature. Like all single-wall tents I’ve tested, massive amounts of condensation buildup on the inside walls drenching any gear touching them.
With the Ace SW 2, much of the condensation forms on the inner wall of the vestibule instead, keeping you and your gear drier. That being said, the head and foot ends of the REI tent accumulate condensation as well, so still bring a pack towel to wipe down the insides.
Because of the three-pole construction (two diagonal poles that cross at the middle and another short pole that attaches perpendicularly to help create a small overhang for the vestibule), venting the two-person tent is easy even if it’s raining: The small third pole lets you open the top of the vestibule to vent while remaining dry in all but the worst conditions.
However, with the vestibules closed, the tent has minimal ventilation.
With floor dimensions of 88 inches by 54 inches and a peak height of 39 inches, the tent is plenty big for two average-size adults and is posh as a solo tent.
And when packed, the 7-inch by 18-inch tent fit vertically or horizontally in my Arc’teryx Bora 80 pack as well as my wife’s Gregory Electra.
Setup is a little more finicky than other tents: You have to put the poles through the dead-end pole sleeves in a specific order to make it easier. One person can set it up alone.
While it’s possible to find lighter two-person single-wall tents on the market, it’s hard to find a quality tent that balances weight, features and cost like the Ace SW 2 does. Most other tents of comparable weight and size retail for $50 to $100 more than the REI single-wall.
For $300 (plus another $27 if you want the footprint), the lightweight three-season tent is well worth the money.
