I do not think there is a big problem using a drysuit with Kubi rings that are “Too Big” apart from the extra size getting in the way when using your hands in a confined space. We have fitted the SiTech QCP www.seaskin.co.uk/acatalog/SiTech-Complete--No-Gloves--QCP-Glove-Lock-System--SIT001_60520.html dryglove system for years on suits cut for people with very small body frames/hand size without the users have any issues. Air migration around the wrist area has got to be better when the correctly sized Kubi rings are fitted, but a big difference or even noticeable difference, no.
Can you link to the size guide pdf. I can't seem to find it, thank you.
How much of a problem is it when the ring is to big
