Yeah, the Lifestyle Ultra-Thin is a plain latex condom and the Supra feels like a higher grade product in comparison. They also say that "Polyurethane Condoms Transform Your Body Heat" much better.Trojan Supra is made of polyurethane (non-latex) material that doesn't have the same characteristics as natural latex, which is used on regular condoms. Supra otherwise feels great, though. The condoms itself is not small but rather medium even towards the larger size I would say. The problem is that if the head of your penis is a bit bigger, you might have some difficulties putting it on even if you are otherwise a regular size because the material won't stretch that much. Some sellers even categorize it as a large condom, but it might be an overstatement. Too bad that Trojan doesn't make these in an XL size as well.They seem to vary considerably in size, or at least the way they feel. I'm used Lifestyle Ultra-Thin and several varieties of Trojan, but nothing beats Trojan Supra polyurethan condoms. Then again, someone else here told me it felt real tight on him and it feels slightly loose on me (no danger of coming off though) but the funny thing is I remember us having comparable girth stats.
