Forgot about this thread.
I have the Sublite Tivek with mesh door. The door looks exactly like in the sil version.
I forgot to take any pics of the door itself but you can see the zip in this shot.
As mentioned in another thread it handles condensation very well, in fact as the Scarp fly was wet outside and under the top inside, the Sublite remained dry apart from a small area at the apex where it felt damp but not wet. It also protects very well from the hot sun giving (fully zipped up, both doors) the same temperature inside as in the shade outside at 39 c (102 f). It took a decent amount of rain over two days still remained dry inside. Having both the bottom vent and the Tyvek door open it feels pretty airy and not claustrophobic at all as I sort of expected.
Pretty easy to set up, not as fast as the Contrail (for me) but should be easier for most. And yes, I can see how the Sil version can be a 3.5 type shelter.
