fleece footed pajamas

Moms that use sleep sacks...do you still put your little one to bed in them if they are already wearing warmer fleece footed sleepers? We received a bunch of fleece sleepers for Christmas and I want to use them but we love the sleep sack (since I think it gives him the feeling of being confined like his Swaddle Me used to do). We keep the house at 70 degrees but I'm not sure if he will get too hot in both? How do you all dress your babies for bed now that it's winter?
