>>2823141I have the Lanshan 1 Plus with a T shaped door.
I also bought the 4 season inner, so I can use it year round. I have taken it everywhere, even up mountains.
Things I like:
*It's weight is under 1kg with titanium stakes and polycryo ground sheet.
*small pack size
*small footprint allows you to pitch the tent in most places.
*Large vestibule area. I can fit my pack, boots, chair and table.
*The colour.
Problems:
*The tent's the inner length. When I use a 11cm thick sleep mat, I always have my feet touching one end, and there is only a few centimeters of space between my head and the inner. This a less of an issue with the Pro version which has no inner, but then you have to deal with condensation.
*Pitching can be a hassle. I always find myself fiddling around to get the inner nice and taught.
*There a gap between the fly and the ground which drafts can come in. This is especially noticeable from the front.
*The fly stretches due to rain, and condensation from the fly and touch the inner and come through.
*Included pegs are rubbish, I replaced them with titanium stakes and easton stakes.
As for the Cloud UP 1, are you choosing it because you want a tent that holds up in high winds? Naturehike has come out with a ultralight 1P tent the Star Trail EXT which weights 900 grams. I am considering buying it to replace my Lanshan for three season use. The Cloud UP 1 pro is too warm to use for summer.
