I just received my from MLD Soul Bivy Side Zip, I ordered the Event option.
As a good geek I first tried it in my bedroom since I don't have a garden neither a terrace.
I closed it and at the beginning it was pretty strange, I looks like there were lightings in my bedroom…
Then i understood that it was inside the bivy with the static electricity.
It is actually very strong sparks each time i moved. it's pretty funny.
May be could be used to light fire ;-)
I'll post a more serious review after field testing.
Regards
