I used mine last year and loved it. I wouldn't tree stand hunt without it. I use a climber primarily and it's great to be able to climb the tree with all your gear on your back. It also provides a great padded back rest and station for your calls and gearwhen you strap it to a tree. I was so impressed with it I ordered their gun version of the pack for use after bow season ends. Look at Game Plan Gear's website and view all the particulars. If you dont mind spending a little extra its a great item.
