Anyone used these for keeping cool? The Evap-O-Danna is on Aerostitch:

The Cooldanna can be found here:

I'm wondering which kind to get. Or if there are other kinds out there someone likes, let me know.

 

I've used the Cooldana. Works great on those hot trips across South Dakota.

 

+1 on the Cooldanna. Soak a long sleeve T-shirt, too, if it's really hot. Keeps you cool and your body moisture wont evaporate from the sun/wind.
