The Made in Japan R'Air is possibly the best feeling tube that you can buy. It has the smooth supple riding feel of a quality latex tube yet has the functionality and durability of a standard butyl. It holds air longer than a butyl and can be patched with normal butyl patches.
The reason why the R'Air rolls so smoothly is that has a high elasticity index which helps the tube and tyre conform to uneven road surfaces, not just increasing comfort but also grip.
If you have been stuck riding standard butyl tubes the R'Air is definitely worth a try. Some say it feels like you a running a few PSI less
