Just wondering why baffles run Across the body versus head to foot.

It seems that for a quilt, head to foot baffles would provide a better seal at the pad than would cross-body baffles.

They might require a tricky mid-body cross baffle, but other than that, why not?

What is the history, logic, propensity... behind our current cross-body norm?

With a full-length tube it would be too easy for all the down to migrate to the ends, leaving the middle bereft. Cold ...

Cheers

Roger,
My thoughts exactly.

Except - if you 'magically' put a cross baffle in at, say the hip region, then each tube would then be shorter than a typical circumferential tube - 40" versus 55" for a quilt.

So it seems like a better arrangement, IF you can get that cross baffle in place.

The cross baffle certainly makes mass production harder, but posted elsewhere is the comment that Golite does this in their Ultra 20's.

But then I have to ask 'Since it is not done this way, what Are the reasons?' and hence this post.
