I can't say anything about humidity, but BP4025 seems to work in winter col=
d. I have used it during this winter at temperatures down to -28=B0C.
I did buy it for the less bulk than carrying around a rig of some kind. I w=
ill build and use a rig hopefully this year, but most of the time I'm gonna=
use BP4025 for the convenience since I have photographic gear to carry aro=
und as well.
I'm satisfied with it so far.
