I'd say that yes, they are comparable. They approach seam sealing differently with internal tape on the Feral and a combo of liquid seal on the bottom part of the Colby+ and internal tape on the upper. I have NOT been gentle with the seams on my Colby and after a lot of use the suit still hasn't started leaking. In fact the Colby rarely flushes for me and usually it's due to an event where any suit would be expected to flush.aside from differences in cut/sizing is the Feral == Colby+ in all other aspects?
