Osprey Seral 4

Designed to go fast, the Osprey Seral 4 Hydration Waist Pack is a bike-specific lumbar pack featuring an internal hydration reservoir. Complete with the essential features for a day on the trail while also staying out of the way during the technical phases of your ride, Seral 4 is an excellent lightweight companion for time in the saddle.

Seral 7 boasts a ventilated AirScape™ back panel, providing comfort and airflow throughout, whilst the ventilated mesh hip-belt with pockets gives a close and stable fit. An ErgoPull waist strap closure system further allows for a snug and stable fit. Inside, a specially designed Hydraulics™ LT Lumbar 1.5L Reservoir sits inside a sleeve, allowing plenty of space to store accessories, snacks and tools. The reservoir hose wraps around the body and magnetically attaches to the hip-belt, remaining out of the way until it’s needed. Finally, the blinker light attachment point and reflective graphics will ensure you remain seen during your night-time rides.
