Background: my partner and I have tried most of the larger sized brands available through Lucky Bloke. The ones that rate toward the top for us are Unique Plus, Trojan Magnum Ecstacy, Naked Luxury, and Skyn.
Since fit is so specific for some brands, we wanted to share the dimensions of the user...20 cm in length, 11 to 14 cm girth. This converts to width of 43mm and 200 mm length, all of which means most condoms we have tried in the larger sizes fit comfortably around but they are almost always too short.
The Unique Plus, which we call the "plastic wrap" or "shrink wrap" condom, was the same. Sometimes they would crinkle or roll up during insertion because they just were not long enough to stay put on the outside. This bunching was uncomfortable and very reminiscent of plastic wrap, but overall we liked them well enough to keep using them. The sensation of closeness, ease of carry in their wallet safe pouch, lube compatibility and vegan values were appealing.
When we got to try the Unique Plus XXL we were happy to see they were making it longer! The additional length really solved the problem we were having with the Unique Plus while keeping the positives. No crinkling, no rolling up, very comfortable during use. Quite possibly our favorite. The only challenge we had was the large flare at the base was easy to catch accidentally during removal so the condom would start to come off inside out. This happens because they are very thin, so not easy to feel and tell if you have a good grip without looking. That thinness has benefits, namely comfort, so it's worth it to us to just use more care with pulling out and removal. Hope these are in stock for regular purchase soon!
