Waist bags fanny packs don't make your back sweat or twist your spine. You can carry the weight in your front, swing it around to the back, or sling it over a shoulder. They can go from the hiking trail to the bar without skipping a beat, and they can hold your train ticket and fit into a backpack while traveling. Best of all, they're so much more convenient than trying to fit your enormous phone into a pants pocket. These are our favorites. You're welcome.
