Sam —
When you suggest that the hoody and pants can be put "in their own 500 cu. in. (8.25L) sacks", are you saying that each one of them can be put in a separate 500 cu. in. sack?
I assume that's what you are saying since the combined weight of the cocoon hoody and pants is more than the 16 oz max recommended by Bozeman Mnt Works for 500 cu. in, at least for my XL hoody (11.1 oz) and pants (8.32 oz).
On the other hand, given Bozeman Mtn Works recommended max of 16 oz for a 500 cu. in sack, what is to be understood by the statement quoted below from BPL's website regarding the small (250 cu. in.) NANO stuff sack as suitable for either my "sub-12 ounce" cocoon hoody or my "sub-12 ounce" cocoon pants?
"The "Small" size, at about 250 ci volume, is suitable for storing a sub-12 ounce synthetic or down pullover, jacket, or pants; miscellaneous clothing, sleeping bag liners, bivy sacks, tarps, etc."
From the above, with it being OK to stuff either the pants or the hoody alone in a 250 cu. in. sack, it would appear that it would also be OK to stuff both of them together into a single 500 cu. in. sack.
Unless I'm missing something, seems to be a contradiction between BPL's recommendation and the recommendation by Bozeman Mtn Works for this issue.
For myself, to preserve the loft of the hoody and pants as long as possible, I intend to err on the side of using the larger capacity stuff sack. But I'm curious about the seeming contradiction, which may lead to unhappy results for someone following a possibly incorrect recommendation.
