RE: HOW IMPORTANT IS IT TO BE CONCEALED WHILE IN YOUR STAND?
I carry a searate pack along with my self climber - no problem.
Being concealed in your blind is important but nothing is as important as (trying) to be as scent free as possible and hunting the wind.
You can be 100% concealed but if that deer picks up your scent, you'll never know he was ever there.
Nothing is a close second to scent control.
Just my 2 cents....
