    Use for a VB layer/liner of any sort in UK climate is very limited.

    I do use them here very occasionally, and also in extreme cold, but prefer using breathable stuff as it's more comfortable.

    There is a good argument for using one inside a sleeping bag inside a waterproof bivvy as it stops down bags from damping out, but then you are faced with waking up with dampness next to skin.

    I wouldn’t have thought there was much need for one in the UK unless you’re camping for a long time in prolonged cold conditions (which don’t happen that often in the UK).

    VBLs are normally more use in cold, dry conditions.

    the youtube video seemed aimed to help people who had never camped in uk cold conditions--------a vbl seemed to be a very odd recomendation

    Unsure if this would ever work, based on a building IE you have the exterior/face material then the permeable barrier and set back 25mm from that is the installation.
    I would assume you would have to at least do the same here, but if you just tuck your sleeping bag/quilt into and against the permeable material the down would wet out faster than the synthetic, but the outer material of the synthetic would wet out the same time as the outer of the down therefore @mjh is right.

    That doesn't surprise me about Paul Messner.
