I have seen a few bags that are made with WPB materials and welded seams (Ajungilak Shield, Exped waterbloc, Crux torpedo…
Im intrigued with this:
1) do US companies make these as well(I know FF and such make bags with WPB but are they welded – ie completely closed to water?
2) do they really work as advertised? can you literally sleep in the rain with them like a bivi?? (putting condensation inside the down aside for a minute
3) and back to condensation – so it makes sense to use a vbl??
enlighten me!
