Having a Saddle bag is good, having a saddle bag with different sizes is excellent. The Ortlieb Classic Seat Bag comes in three sizes, Small, Medium and Large.
The small version is perfect for roadies or those who want just a tube or some C02. or the medium which is perfect for Mountain Bikers with tools, combs and bottle openers. The large however, is huge it is a alternative to carrying a backpack, giving you room for equipment, snacks, extra shells and tools for long day touring, randonneuring brevets, or maybe minimalist commuters without racks.
The Ortlieb Saddle bag sits perfectly under your saddle and can also act as a protector from mud. And, trust us, riding with a muddy butt all day is no fun. This bag is 100% waterproof with a roll closure with buckles and d-rings for locking the bag.
