What Our Gearhead(R) Experts Are Saying:"The Syncro 5 is perfect when I want to go fast and light. The airflow on my back is unreal-no sweaty hot spots-and it's got just enough room for a spare tube, tools, and snacks. The included reservoir and rain cover mean I'm ready for any weather or trail."When the goal is speed, simplicity, and staying hydrated, the Osprey Syncro 5L Hydration Pack delivers exactly what we need for fast-paced rides. Its compact, low-profile design carries essentials without adding bulk, while the AirSpeed(TM) suspension keeps air circulating to keep us cool and dry through long climbs and hot conditions. The included Hydraulics(TM) LT 2. 5-liter reservoir with a magnetic bite valve ensures easy hydration on the go, and the bike-specific BioStretch harness hugs close to the body for stability over rough terrain. The front mesh pocket and internal tool organization keep spares and snacks right where we need them, and when the weather turns, the integrated high-visibility rain cover keeps our gear protected. Built with recycled, bluesign(R)-approved nylon and PFAS-free coatings, the Syncro 5 is the ultimate minimalist bike pack for riders who value comfort, ventilation, and hydration efficiency on every ride.
