I've hunted deer for years from a tree stand 15' off the ground. But I've always had to wonder if Mother Nature would shorten my hunting trips...until I discovered TravelJohn Disposable Urine Bags. Now, I'm even more relaxed than ever before, and when I need to go...I go! It's odor free and stays high up in the tree with me. And when the hunt is over, I carry it out without a problem or concern about spillage. I carry them with me when ever I travel. You won't be disappointed, as there is no smell, leakage, or any other unpleasant aspect to this great product.
