I think...I've worn my black trekker waist pack every day, for...five YEARS?! It's my fanny purse, my purse, my over-the-shoulder dinner bag, my grab 'n go. It's never broken, shredded, come apart, or ripped. In the supermarket you have both hands to shop, and the double zipper compartments make it very easy to grab your cellphone, and never lose it or leave it anywhere. It's really....PERFECT. My other gal friends go searching forever for the kitchen sink in their bladder bags, Lordie. Forget it. This is the BOMB. THANK YOU, for still having them!!
