The JHMCS does work at night and has a clear visor, but you give up the NVG's. There is supposed to be an NVG adaptation to the JHMCS but I'll probably retire before it comes out.
JHMCS is a great piece of gear. It takes between 2-4 hours for the PR's to fit it to your noggin. They have to cut the visor to fit your face / mask and adjust the padding in the ear cups and the top of your head. There are different thickness Zeta liners that help a lot. Then some fine tuning after the first couple of flights.
The time is well worth it.
