Boao6 Pieces Skull Caps Helmet Liner Sweat Wicking Thermal Running Beanie Cycling Skull Caps for Men Women

Can i order them all black?

can I just get the caps in blue or gray , not the black?

Can you get a set of 6 in safety green?

Can you wet these to cool your head like the mission skullcaps? Or is the design different so it wont have the same effect?
