I've got the sleeves (both DeSoto and Zoot) so I'm not sure how much the sizes relate. I don't run or ride in anything sleeveless, so a bolero wasn't an option for me. But one thing to know about the DeSoto fabric is that there's VERY little stretch to it.

Not that I really wanted to know how much upper body muscle I've lost since my shoulder injury ... but I just measured and I'm 11" above the bicep/below the delts, at the smallest part of my upper arm. Even though this is smaller than I was when I originally bought them, the Small would not even go on my arm, that's how tight they were. Size 3 "fits," but the sleeves are an odd shape, which wouldn't be an issue if you get the bolero.

Zoot fabric is very different and they behave differently getting "up to temperature." I don't know much about Houston's climate. I'm guessing it's pretty humid. I think in an arid climate, the DeSoto fabric might work better, but in moderate to high humidity they both get saturated pretty quickly, and once they're saturated both of them function pretty much equivalently.

The Zoot sleeves don't have grippers, just fabric-covered elastic at the top, and they stay up very well. The fabric is also stretchier. So if most of your jerseys have sleeves that might still be an option for you.


I've heard very good things about the Craft cooling garments too, but haven't even seen them IRL.
