The Pro rainfly has been upgraded from 15D PU & Silicon nylon to 20D double coated Silicon nylon, and Pro is 3 times more robust and tear-resistant than the regular version. So pro is more suitable to be used in extreme conditions. In landshan Pro tents, inner tent layer and rainfly are connected together.
So Pro is single-skin, smaller packing size and more lightweight. But as you know, single-skin tents are not so good at dealing with condensation.
Now you make the choice... Rainfly Roof: 20D nylon coated with silicon on both sides.3-season Tent: 20D breathable nylon mesh. 4-season Tent: 20D nylon cloth. Bottom Of The Inner Tent: 20D nylon coated with silicon. Size(Length Width Height): 230cm 120cm 125cm. Color: Green / Gray / Khaki.
Note: This tent needs to be seam-sealed by yourself! Your need to prepare the glue on your own.
