Oh - it was me with the arm coolers - still swear by them! They're made by Desoto sports - here:

3rd item on the list. I'm serious - these rule. We have so many people asking about them!

Also, Boure (Ned Overton's company in Durango) makes an SPF50 jersey that my BF swears by - it's green and yellow, but he's worn it all summer long (on days he's not using the arm coolers) riding in Miami, and he loves it.

Note to admin: y'all should consider adding some of these products to your lineup!
