I prefer the Okamoto 0.02 over the 0.01
0.01 rips very easily
0.02 is a good balance
Japanese condoms are mainly Polyurethane (don't really recoil, which is the main disadvantage)
American condoms are mainly Latex
Both stretch, so... you "XL" guys are just hilarious... give me a break, it is just a lot of marketing... and yes, I have used trojan XLs as well.
