The Fox Racing Lumbar 5-litre hydration pack is a low-profile hydration and storage solution. It is made from ultra-durable 600D polyester and measures 10.6 x 8.7 x 3.9 inches. It boasts a 2-litre HydraPak reservoir and a fleece-lined pocket for your valuables with a 5-litre storage capacity. It is comfortable and non-intrusive and, as it is a bum bag, doesn't put weight or pressure on your shoulders. It has a key clip, a magnetic hose retention and reflective trim.
