Hi folks thanks for the advice. Been busy today not had a chance to reply.
I should have been a bit clearer.
I'm talking about a wet Winter in Scotland.
Wether I'm under a tarp or in a tent,using a bivvy bag or not.
My bag is always covered in a layer of condensation.
after a couple of days the bag is useless.
I'm a warm sleeper and think that the bag may be too warm for me.
