I'd been thinking about a bivy for years, my tents fairly light (<2kg) but this thing is a mere 0.8kg.
The dark green color is really nice, the eVent upper and and nylon floor are both quite soft materials, so they feel comfortable and don't make too much noise.
The eVent stormhood is 3D, but not so obvious from the picture is that the insect mesh is 3D as well, you need to tie it to a branch or similar, but it works very well and keeps your face and shoulders free. It's looks like its also possible to have both the insect mesh and storm hood done up.
The stuffsack is just the right size. The eVent breaths quite a lot for a waterproof material.
I really like this bivy, I'm slim, and found this quite roomy. I never felt restricted in movement by the bivy (but rather, just the sleeping bag).
I haven't had a chance to test out the waterproof zip yet, though of note is that if you plan to setup camp in heavy rain, without a tarp you will get water in the bivy when you're getting in (I wonder if you could be creative and rest the bivy with the top against the ground, get in it, then roll over so its upright...)
I'm quite happy with the price, and very much recommend it.
