When we set off to the design the Rover Hip Pack, our number one gripe about other bags was their tendency to move around a lot on the lower back while riding. This made riding with a pack feel more distracting than helpful, especially while sending it on the declines. The strap system on the Rover is designed to minimize any of this movement. With its adjustable "wings" on each side of the pack you can fine-tune your fit, followed by securing the main straps with velcro tabs (shown in the video above) and your Rover will comfortably hug you down the trail without slipping and sloshing around.
