The only one I've tried is the Terry, but my biking partner has a couple of the Sheila Moon. Her SM boleros have very long sleeves, which she is thrilled with because she's tall and has really long arms. It's cute (she got a couple of different colors) but rather thin, no warmer than a standard long-sleeve jersey fabric. Best for temps no lower than 60F, I'd say, unless you're more cold-tolerant than we are here in NC!

The Terry is warmer than the typical l/s jersey, with a fleecy inner layer that feels great next to the skin. The sleeves are also very long -- a bit too long on me since I'm petite, but better than too short. I really like it. Mine is several years old, so they may have changed them since then, but hopefully not as it's a very nice item. Perfect over a sleeveless jersey in the morning when it's going to warm up, or after a rest stop when starting back out.
