The Osprey Seral 7 is a versatile hiking waist pack designed to keep your essentials close and your hands free. With a modest 7-liter capacity and an integrated hydration system, it sits comfortably around your hips and offers quick access to gear and water on short treks, trail runs or everyday outdoor outings.
Despite its compact size, the Seral 7 holds up to 7 L of gear and comes with a 1.5 L hydration reservoir. Weighing in at just 0.38 kg, it stays snug against your body to minimize bounce and balance your load. The streamlined design and adjustable hip belt ensure you can carry snacks, a light jacket and your water supply without feeling weighed down.
A drink reservoir is a flexible water bladder that fits inside the pack and connects to a drinking tube with a bite valve. This system lets you sip on the move without fumbling for a bottle, and the 1.5 L capacity means you can stay hydrated longer between refills. The reservoir tucks neatly into its own sleeve, making it easy to remove for cleaning or filling.

Osprey says about the Seral 7
Bite Me. Designed to go fast, the Seral 7 is a bike-specific lumbar-pack featuring an internal hydration reservoir. Complete with the essential features for a day on the trail while staying out of the way during the technical phases of your ride, Seral is an excellent lightweight companion for time in the saddle.
Seral features a ventilated AirScape backpanel, providing comfort and airflow throughout, whilst the ventilated mesh hipbelt with pockets gives a close and stable fit. Dual compression straps on either side further improve the packs fit and stability during active riding. Inside, a specially designed Hydraulics Lumbar 1.5L Reservoir sits inside a sleeve, allowing plenty of space to store clothing, snacks and tools. The reservoir hose wraps around the body and magnetically attaches to the hipbelt, remaining out of the way until it’s needed. A front-panel pocket provides some organisation, including a scratch-free pocket for electronics or glasses, and a mesh pouch with key-clip. Finally, the lower LED Light attachment point and reflective graphics will help you be seen during your night-time rides.0
