Seral 7 w/Res

Stay hydrated, stay moving. The Seral 7 is a stable, lumbar-style bike pack built for longer rides where hydration and quick access to snacks and gear matter most. An included Hydraulics™ LS 1.5L Lumbar Reservoir with magnetic bite valve attachment puts water within reach without breaking stride, while a bike-specific airmesh wrap hipbelt and AirScape™ backpanel with center airflow channel keep things comfortable and stable on rough terrain. Dual hipbelt pockets handle snacks or a phone, and vertical front accessory straps secure a chin guard or extra layer — tucking away cleanly when not needed.
