I'm with Terry on this, I have a fleese one that i dont have a problem drawing arrows out of and don't notice any extra weight or noise! I started using one after being busted by deer on the draw, I figured out that what they were seeing is the movement of the lite collored fletching aginst a darker camoed back ground, even the slightest movement they would catch! Since I've started using a cover I've been able to draw on game undetected, now i just have to start hitting what i'm shooting at more often!LOL
That's one on my recurve in my avatar, it covers up the brite white and yellows of fletch and crowns!
