Just for Nigel (ok, for me) I put and extra base layer on today (T-shirt style) going for the multiple thin layer approach, and dry gloves
So, a T shirt style base, a thin top and leggings base layer and set of Artics & dry gloves with fleece gloves below.
9oC in the shallows 8oC at depth. It was 60mins before I felt cold, and left the water after 74 mins, so was cold but not uncomfortably so. I didn't even fin about on the stops
