Durex -UK- used to make one called "Gold" which was their flagslip and was pretty expensive if I recall. The rubber was one of their thinnest, teatless so it covered your knob just like a second skin and it was gold in colour. This I found to be the most comfortable.
The jap Akimoto or some kind of another is also pretty good on the thin side; but some can be pretty uncomfortable because the girth is too is not as accommodating as some of the other brands.
