The ring size is another reason I much prefer the Kubis. I had a SiTech system on a previous suit. The rings were huge on me. Even the Ultima were big on me, plus I had major issues getting them locked on without help (hand strength issues again). The Kubi rings are small enough (80mm for me) to make a difference and I can lock them on without issue. I have small hands (my glove liners are size small). The thin gloves give me good dexterity for dealing with clipping my tanks on (SM) and I don’t have the issue of fingers 1” too long like I’ve had with other gloves.
