We’re calling this the Transformer of fanny packs. The Sidekick Medium can be worn as a traditional lumbar pack or as a cross-body sling bag. Or you can remove its 1.5-inch waist belt and use its hook-and-loop tabs to connect it to MOLLE attachments or various points on your get-out-of-dodge bag, thereby increasing your carry capacity. You could even connect it to the handlebars of your mountain bike or motorcycle. It’s made from 305-denier Cordura HP with a 210-denier nylon embossed liner and YKK zippers. Weighing just 6 ounces, the 1.9-liter Sidekick Medium can hold up to 7 pounds of gear.
