I don't think this relates to your question about the SI Tech system but I do think I have found an alternative for dry gloves. I had plain cuffs installed on my Viking Extreme last fall and have been trying to find the right glove system since. I do not have any wrist seals. I tape the gloves directly on to the cuffs and slide my hands in as I am putting the suit on. This requires using thin gloves so that you can continue putting the suit on, gearing up, etc. I have been using blue chemical gloves, size L that I bought at Lowe's for 5 or $6. I have been using those cheap disposable "hospital" gloves underneath to help slide in and out. I have been spending up to 1/2 hour in 36 to 40* water with them. My fingers do get cold at times and I shoot a little air up the sleeves occasionally. But I just recently bought the black latex/rubber chemical gloves at Lowe's [$6?] and installed them. They are a little thinner than the blue gloves and the cuff attaches a little easier inside the sleeve ring. Over these I wear a pair of Waterproof 3MM G1 "XXL" gloves that I put on when I am set to dive. Before I was unable to slide these easily onto the blue plastic gloves, but they puill over the black latex gloves with no problem. The beauty of these G1 gloves is that they are a zip up and have bite/grab tabs to help get them on. In the past I have used different types of gloves for the wetsuit and drysuit [before installing replaceable seal system] but have difficulty getting thick gloves on. The Waterproofs with the zipper wrists are much easier. I do get a tiny bit of leakage through the cuffs but I can deal with damp sleeves.
