The last years I've been using the SiTech Antares dryglove ring system. "Why?", you may ask. Because when I went for the Antares ring system I knew eff-all about dryglove rings, and my suit (Waterproof D7) came with silicone seals and arm rings easily compatible with the Antares system. No modification necessary, just buy a set of Antares rings, attach to the gloves and swap the inner ring on the suit with the one in the box. No gluing, no hassle.
But right now I'm pretty fed up with the Antares system. It's always been a tad finicky with getting it to seal properly, and it's a real PITA to doff the gloves. More than once I've had to doff my suit with the gloves still attached, and detach the gloves later since the method for detaching the rings dont... work as SiTech says it should. To top it up, last weekend I broke one of the clips on the glove ring. Luckily, the boat had a roll of electrical tape available, so I could secure the glove ring to the suit ring with tape and avoid a serious leak.
So now I'm seriously thinking about switching to another ring system. However, I want as little hassle as possible, and I want to be able to continue using my silicone wrist seals (I love them. They're less durable than rubber seals, but so much more comfortable, so I'm fine with sacrificing durability for comfort). I don't expect to avoid switching the rings glued into my suit, but continuing to be able to use the same silicone seals I'm using today is high priority. right now, I'm looking hard at Waterproof's Ultima system, but any suggestions or input would be appreciated.
