A solid, spacious seatpost bag that is durable and waterproof. It's easy to attach, pack and unpack and can fit everything you'd need for a long day out on the trails.
Versatile and lightweight: one simple tool free manoeuvre is all it takes to fix or remove the waterproof Seatpost-Bag made of PU coated nylon and Cordura®. The integrated mounting allows quick change from bike to bike. The roll closure with elastics ensures safe closing of the bag and allows tight packing. The Seatpost-Bag is available in two sizes, the 1.5 litres version being suitable as additional bag for longer trips, the 4 litres model might even replace a backpack. Both versions will protect the rider from splashes and dirt.
The Ortlieb Seatpost-Bag 4L is a solid, well constructed piece of kit. The seat post attachment is solid but simple to use and can be adjusted to fit snugly around your seatpost. It is made with a couple of durable waterproof fabrics that ensure everything stays safe and dry inside. There is a plastic frame inside the bag to keep the shape and provide a little extra strength.
There is a large internal storage space with two small mesh pockets to keep things organised. The main part rolls closed and has two simple elasticated fasteners to keep it simple and easy to access. On top you can stow jackets or other bits under the adjustable elasticated strap. It is bulky and things do rattle around in it due to the shape if its not full so that may be something to think about.
