Bug-free tarp camping at last
Paired this with my flat tarp on a humid July trip and it was a revelation. Full head-to-toe netting with a little hoop for breathing room at the face. Under 10 ounces for total insect security — I'll never do a tarp trip without it again.

Does exactly what it should
Kept every mosquito out over three sweaty Alabama nights. Set up is simple with trekking poles and a few stakes. Not a shelter on its own, so bring a tarp if rain is in the forecast, but as an ultralight bug solution it's superb.

Slept under the stars, zero bites
First night I've ever slept fully open to the sky in blackfly season without a single bite. The mesh is fine enough for the tiny bloodsuckers too, which is rare. Packs smaller than my water bottle.

Good netting, fiddly setup
Protection is excellent once it's up — no bugs got in. But getting it pitched taut on rocky ground took some trial and error, and the stake points are minimal. Give yourself time to practice in the yard before you take it out.

So light I forget it's packed
Ultralighters, this is the one. Stuff sack is tiny, setup takes two minutes, and the floor adds a nice bit of ground protection under my pad. Used it on five trips this summer across two states. Flawless.
