"Also if you do hunt with one on, which do you use... i was looking at this one from cabelas."
I have one of these and never leave the house without it. keeps your clothes out of the way while still protecting your arm.

Or you can get the mail and take the rubber band off and use that....

i ALWAYS do when i have bulky clothing on! JUST to compress the sleeve...

If i'm wearing bulking clothing i use rubber bands, they work great and are cheap

I missed a 12 yard late season doe because I forgot to put my arm gaurd on. [:@]
String hit my arm, threw the shot left, the arrow whizzed just in front of her brisket, and stuck in the snow just behind her. She heard it hit, and turned toward it to check out the sound, bu tI never got a second shot because of the other doe she was with. Too many eyes.

All the time.

I use the Realtree EZ Arm Guard when I am wearing long sleeves. It does a good job of keeping the sleeve out of the way.

I do wear one when hunting in a heavy coat or my thicker leafy camo..
When just shooting I do not but while hunting.. Yes...
