How do you secure these gloves to your dry suit? Is this just a friction fit over the rings? I've been using something similar to these gloves but they included a very large o-ring that helps to seal the glove. The o-rings are a challenge to put on with the gloves on and I've had one of the o-rings roll off the cuff and the gloves did leak. I have been considering other glove systems that would be easier to put on and remove but now I'm wondering if I'm missing a better and easier method to use these gloves.
