Having a Saddle bag is good, having a saddle bag made from high visibility woven PU material is even better. The Ortlieb Classic Seat Bag comes the large size.
It is huge and can almost be considered an alternative to carrying a backpack, giving you room for equipment, snacks, extra shells and tools for long day tours.
The Ortlieb Saddle bag sits perfectly under your saddle and can also act as a protector from mud and road spray. Riding with a muddy butt all day is no fun. (Trust us) This bag is 100% waterproof with a roll closure with buckles and d-rings for locking the bag.
