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.
