Some folks have hijacked my other thread so here is a new thread..
If you are using a quilt with a full insulated footbox with just a torso pad then 800+down will easily compress if even some part of the legs touch the the ground. Chilly legs are alright but what I want to know is whether they act as heat drains? If legs get chilly does body lose heat overall? that could compomise the insulation of my setup.

An expriment I am interested in is keeping my legs crossed while sleeping on my back and legs curled when sleeping on my sides. I will need a wider girth at the bottom of my quilt but the overall weight can be significantly reduced and it will be warmer because of less surface area.
I opened up the footbox of my quilt to try sleeping with my legs crossed. Too fussy. And foot girth is a bit narrow to prevent draft.
Then I slipped bottom bit of quilt under my the bed. less fussy. I think a 3/4 quilt with bottom attatched by zip or ominitape to 3/4 pad would be best for this style. But you will need to loosen up the whole quilt everytime you want to change pose.
