When you're riding, you don't want to think about your pack-and the Syncro 5-liter pack's streamlined profile ensures that you won't. With an included updated Hydraulics LT 2.5-liter reservoir, ventilated AirSpeed suspension and included raincover, this low-volume, minimal bike pack is the perfect option for desert heat or humid climates where you need nothing more than hydration and a few essentials.
