Pros

Side block baffles prevent down migrating around the bag
Breathable 15/20D nylon fabric lessens sweating
Decently sized footbox
Storage and compression bags included
Splicing bag - M and L sizes can zip together to create a double bag

Cons

At ~1kg it is not ultralight
Regular version a bit narrow at 78cm
Differential fill means less down on the bottom than the top - if a side sleeper your back is less protected
M zips together with L only (not M-M or L-L) due to zipper placement
Medium size difficult to stuff into compression bag - large version comes with bigger compression bag
