for the price they are okay, I have used mine in all sorts of weather, but I don't recommend using it in the rain, mine leaked like a sieve when I tried this, the arm holes were the culprit, I had guys saying that I had put it up wrong, but there were some experienced bushcrafters and wild campers who posted vids on you tube that I copied, judging by the pics posted in here the guys were right I pitched it wrong, I also fabsilled it inside and out but those arm holes were leaking badly,
I ended up throwing a tarp over it in the middle of the night to keep dry
Like I say in the dry they are fine, probably a light shower they are okay, any more leave it at home, I also agree with a previous poster, that it is around 1.8m inside, I will probably never use mine again because of the weight and its inability to shed water
here is a link to the vid I posted on You Tube when I used the Lavvu last, PS no laughing lol
