Though Fizik makes other under-saddle storage options, here at Excel Sports, the standard Saddle Pak (Medium) is a staff and customer favorite. The lightweight, highly water resistant Cordura fabric is durable, and has reflective properties. A single sealed zipper with a long tab gives direct access to the storage space- in this case .6 liters. Simple rail and seatpost velcro straps make mounting/removing easy and quick.

The Medium offers storage for two tubes, a small CO2 inflator, tire levers, and few thin extras, which is perfect for most road rides. The bag is still compact and when fastened tightly, won't sway or move. The rear facing tab can be used for a clip-on light, and has reflective zones. In our experience, the Fizik Saddle Pak has been durable, easy-to-use, and requires little thought. In other words, perfect for what it is- a compact saddle bag that gets the job done.
