Familiarity: I've used it several times
So far I have used this tent in summer and fall on backpacking and bike trips with my dog.
It is definitely super lightweight! And I find it still fairly spacious inside, regarding it's a one-person tent. There was even room for my husky joining my feet. Pockets insideto stash away little things like your glasses/headlight/maps come in very handy.
With it being ultra-lightweight gear of course comes some vulnerability of the material. At first I was kinda worried something underneath the tent might punch through the bottom (even though I am always using a footprint) or the dog's claws might punch through, but it stood its ground so far. You also have to be careful with the mesh in the inside wall. I was also really amazed about the venting in this tent. So far I usually had issues with moisture builtup inside, especially in the fall. But even with heavy rainfall and thunderstorm outside, everything inside this guy stayed perfectly dry. Also, there are many ways in tying it down in case of heavy wind, or if everything seems clear as far as weather goes, you can just put it up, sneak in and fall asleep. No need to anchor it down, it's free standing. I did have to get used to setting up the poles, but after doing it a couple times it really is handy that they are all connected and just fold together. Having used a Hilleberg Nallo 2 for years, I am used to cooking in my vestibule in case of bad weather. With this tent, you'll still get wet doing so, just because of the construction of the "vestibule" but after all, it is still a great ultra-lightweight companion!
