Thanks for the tip Deb. I went ahead and ordered the zepher cap. Your review helped a lot! I didn't realize it would cover my ears from the picture, and I have been so impressed by quality of Ibex, even over smartwool. In fact, I added to the order some ibex glove liners so I'll be all decked out in ibex from head to toe on the bike now (to add to my arm and knee warmers). I'd struggled to find leg warmers that fit, but the ibex knee warmers in a small (sizes posted here on TE) fit like a dream (w diff. thigh measurement than leg warmers, odd but true) and are on a really good sale now at ibex site. They took a few rides to learn how to position, the lycra/windblocker fabric goes on the front, and they are right and left specific (follows the curve of your knee) but if you pay attention to positioning they work like a dream. I think they will effectively work like full leg warmers when paired with wool socks, and therefore are a very versatile piece, especically for touring. They are great now for our in between weather where mornings are still cold enough to have my knees covers but its warm to downright hot by afternoon.

I should add that I have a sugoi helmet cover to keep the wind out of my helmet's air vents if its really cold, but wanted something to use between lycra headband and balaclava weather. Seems like the zepher skull cap will fit the bill nicely!
