For you guys that "black out" in your blinds... what is your favorite black facemask/headnet?  Seems like the boys at Double Bull used to use some ninja brand that was very thin, stretchable, and lighweight?
I have a black ScentLok facemask that is a heavier fleece-lined material that I bought for deer hunting out of a pop-up blind.  It gets a little too warm in a blind with the sun beating down for it in the spring.
I like mine to have a little stretch or give to it, as I drop it down to find my anchor point before the moment of truth.
Any recommendations?
