Cool Wings - product review

[supercutie]

I just bought the De Soto Cool Wings - it was either Cool Wings or the Canari Cool Max Long sleeve jersey - but I decided the wings would give me more options, in the event I wanted to lose the extra layer I could just stuff it in a pocket. Plus the Bolero styling looked a lot more comfortable than the arm tube styling of Arm Coolers.
I'm in southern AZ where the temps are a 'chilly' 80 over night and 100-107 daytime, plus it's Monsoon Season so we have humidity ( 20-35%). When I got the Cool Wings I modeled them for my husband, we were standing outside at the time (106 in the shade), and as soon as I put them on they cooled my arm. (even my husband, who had to try them too, noticed a difference) I wore them this past Sunday on a 36 mile ride that took us 3 hours to complete, hole in tire = changing tube and repairing tire. They WORKED! The only time I thought they might not be 'all that' was while climbing a challenging hill in open desert. But once I was over the strenuous bit I was fine and figured I'd be feeling the heat no mater what I wore.
As for size... I decided on a medium. I have tiny wrists and the well developed upper arms of a 47 yr old woman who is also living with the reality of saggage.
I wore the Wings over a sleeveless jersey and had no issues with gaping at all. I did have a bit of skin showing at the glove line but that is only because I can't stand anything around that part of my wrists. All in all, a hit. Now I'm thinking about that Canari jersey again... any input on that?
