I dont know what happened to it but we used to have a conbination thing with two that fastened together to make a 15tog, but the two parts were different and one was a 4tog. The remaining bit sounds like you might expect 11 tog but from.memory was 9; presumably the insulation of the air in between them has a tog value as well. Anyway, it meant you effectively had 4, 9 and 15 which you could change to match the season, but it was all too much of a faff really. Wr have moved house a lot, changing bedroom configuration and whatnot so I suspect we have the largest collection of spare duvets iutaide a salesroom.
