side/edge seal on UQs- how important?

[BillyBob58]

If you assume all things are equal and all the design issues are resolved, then there are 2 sides to this. A truly insulated hammock isn't capable of being vented during times where you might want to do that... but it won't vent on you during times where you don't want it to do that. There are no issues of sealing it around the edges.

Now that brings up an additional question. What about being sealed on the sides? How much of a factor is that?

The reason I am asking is because of my use and theories of the pod approach. I quickly became of the OPINION ( based on no actual evidence) that one reason why my PeaPod seemed to work so good- so darn easy to stay warm with almost zero learning curve- was because the edges were sealed with the bag overlapping the hammock edges as the pod closed in the center top. It seemed to me that this 100% eliminated cold air sinking down along the edges and, if any gap at all existed, getting under your back. Plus it was pretty well sealed on the ends. Thus the result was, if completely closed up or mostly closed up with a top quilt, about like being sealed in a mummy bag. Or, even if not closed at all, the edges were still sealed.

While using my SS or UQs, sealing along the ends or sides can present various challenges, depending in part upon which system is being used with which hammock. ( EDIT: and though this can usually be worked out by correct adjustment, things might still change if you shift position too much during the night, like going from back to side or from left side to right side, etc) The issue of "closing the windows" on the ends is well discussed( or opening them for ventilation when warm), but how much of a factor, if any, is sealing along the sides/edges?
