It's not the lightest, but if you get the Castelli Sanremo Speedsuit you can ride with it unzipped the whole time, which to me is better than having a light jersey. Even when fully unzipped, because the jersey is stitched to the bibshorts, the pockets never sway or sag. Plus having no bibstraps is surprisingly comfortable too.

+1! I just wore mine for the first time this weekend in 90 deg F. The lack of straps is great, but the mesh back and sleeves are perfect for keeping cool.

This Leopard Radioshack jersey looks very breathable. Saw it in cyclingtips. Now where can we get that jersey?

My wife just surprised me with this yesterday, Rapha Super Lightweight jersey.

Will ride on Saturday and return with a report.



Tried it on last night and fit great, and felt very light. This thing will be mincemeat if one of our cats gets anywhere near it.

What does it weigh?

I'll put it on a scale tonight

This is size medium and I think the medium is claimed to be about 125g.

Mavic's Helium series is very good for hot rides. Check it out.

I also like this jersey. http://www.solocc.com/jerseys-and-base- ... ght-jersey . It's unique, because its a fairly new brand, but mostly, it's light weight and white....which although not flashy, is the best color to keep cool in the sun.

Craft Elite Attack, you can buy it lots of places, nice jersey.

That't hot.
