On a hot day, I love my grey Camelbak Vent gloves. They even go great with the ACU. Basically the same protection against bb's as Mechanix Originals, that is to say... not much.
Heard about them on MM, many moons ago:

Bought them here (though they are discontinued, you can still find them, and what savings!)
