Try sealskin waterproof/windproof gloves, should still have reasonable dexterity (and also rubbery dimple grips fo erm.... grippyness!).My issue is cold hands. To combat that I put on layers but you need dexterity for setting camp up. This means only thin liner gloves at best. Wind goes through them and next to useless without proper warm gloves or mitts which mean no dexterity.
I meant an all round tight fit. However 2x compressed insulation is still better than 1x compressed insulation
Redwall is quite correct. The insulating properties of sleeping bags work best when used with minimal clothing on. If you sleep in your clothes then it is your clothes that you rely on to keep you warm, but they do not have the insulating properties of a bag. The result is that the air in your bag is colder than your body temp, basically your climbing into a fridge and zipping it up. If you remove the layers of clothing your body warms the bag and it stays warm. You then have a bag of nice warm air to sleep in. So its either in a bag of warm air semi naked, or fully clothed in a fridge. I know from lots of experience which i will choose. I would advise you to try it before you doubt it
Another good idea i use is to take a couple of the reuseable gel handwarmers. Warm them up 15 mins before you turn in and throw em in your bag, top and bottom. Your bag is heated then before you get in.
Complete tosh.
More layers simply mean more layers of warm air around your body. How on earth does your sleeping bag know what you are wearing? I'd be intrigued to know the answer to that one.
As for the air in the bag being colder than your body temperature and working like a fridge, well, I don't know what to say, it's just nonsense. A fridge works by circulating cold air, in a sleeping bag air does not circulate, but hangs around and warms up. Otherwise on very cold nights you would simply die of hypothermia.

The last chap that doubted my theory came out quite politely. Discarding my theory as complete tosh strikes me as being something of a throbber.
I am not here to rile anybody up and I certainly will not be adding another single post but now that two other people have come out of the woodwork backing up my suggestion I would like you to know that I am quite hurt by your comments. Think about that in future and sleep with all your layers on if you so wish.
You'll be telling us next that we should take off our jacket when we go inside or we won't feel the benefit later, or if we go out with wet hair we'll get a cold!
Put simply as I understand it, it is the air trapped in the fibres of your clothing or sleeping bag that provide most of the insulation (being a poor conductor) and your body that provides the heat from metabolism.
If you are wearing so much clothing that it compresses the fibres and therefore squeezes the air out of your bag and your clothing, then they will not work very efficiently.If there is enough room in your bag system (including your bivi bag if you use one) not to compress that fabric then it will provide better insulation.
A factor that complicates matters is overheating which can add moisture to the system which seriously increases heat loss through conduction.
Another comfort factor is having something cosy to put on in the morning to replace the insulation you lose by getting out of the sleeping bag. This could of course be offset by the increased activity during the day which reduces the effect of this factor.
Both systems have merits; "Yer pays yer money, and yer makes yer choice."
