One thing regarding the cloak that really helped me out in getting it on was snipping the two nylon threads leading up to the curved seam in the crotchtal area.
It's best compared to when you buy a new suit & the pockets are sewn shut. You have to cut those threads to open access to the pocket, so I figure you have to cut the tiny cloaks threads to put the thing on. With that seam going all the way through & around I feel confident that it won't damage the integrity of the stitching.
....well I'm at least trying to make myself feel confident. Anybody else resort to that?
