Like giblett I have more of an issue seeing around my clothing when its cold. I'll admit it is harder for me to pull my bow...so I have no doubt it really does prevent people from coming to draw. But my 60# is borderline too low for me (hey, I'm big and in college...enjoy it while it lasts, right?) and I can hold draw for a solid minute without much stress. I'd recommend taking off 5lbs and learning the secrets to staying warm on stand. (keep that neck warm!!!!)
