Perfectly! I have the bigger Red nano
The nano fits into this normal cles but only JUST - I haven't seen the new cles in real life yet but I assume it will judging from pictures that I saw and from everyone here saying they're much more roomier.
Notice that I haven't taken out the plastic wrap around the zipper yet - I'm contemplating returning this cles and wait to get the new one (it's not yet available in Australia). This cles fits my ipod nano but it doesn't fit anything else at the same time...
Hmmmph what to do? what to do? :s
