I took this bivy out for a Colorado trail bikepack/fastpack mission during this very wet summer with heaps of mosquitos. The mesh is such a game changer, and kept the mozzies out along with rain spray coming in under my tarp. I love how roomy it is (I'm a side sleeper, this is important) and the pad ties on the inside worked great to keep my pad from sliding around. And, it's even lighter than my old bivy which is a tighter fit and has no mesh, rolls up great in my bikepacking sleep kit burrito. I definitely recommend it!
