Osprey Seral 4L Hydration Lumbar Pack
If you need storage while out for a fast day on the trails, the Osprey Seral 4L Hydration Lumbar Pack could be a perfect choice. Designed specifically for use on the bike, the lumbar pack has an internal 1.5 litre hydration reservoir and its hose wraps around to magnetically attach to the hip belt allowing for easy access when needed. Separate to this is the main compartment, with plenty of space to carry an extra layer, food or other bike gear. An external back pouch is designed for small, easy access items like glasses and keys, keeping them ready to grab when it's time to head home. All your luggage is secured by dual compression straps that make sure bounce and sway are minimised when riding, helping you to forget the bag is even on when you ride.
The pack's low profile design is complemented by its use of Osprey's signature Airscape Backpanel which allows air to flow between your back and the bag so you stay cool whatever the temperature. Another important finishing touch comes in the form of reflective detailing that helps you to stay visible if your session goes on into the night as well as a strap to attach a visibility light.
