The Seat Pack is a large waterproof pack capable of carrying a significant amount of kit on your next adventure. As with the rest of the Ortlieb bikepacking range this is a high quality product that is well designed, with a strong durable construction. 

Ortlieb says:

All systems go for your next bikepacking adventure! Conveniently mount the ORTLIEB Seat-Pack to your seatpost with the help of two extra strong Velcro straps. In addition to its other duties, the seatpost bag serves as a fender in off-road terrain. The spacious, waterproof Seat-Pack keeps your extra clothes dry. Go ahead and dial in the pack’s volume from 8 to 16.5 liters via the roll closure on the side to meet your stowage needs. Use the convenient compression valve to make your pack even more compact. And what should you do with your jacket on those uphill stretches? Simply stow it under the quick-access, X-link restraining cord on the top of the pack. And once you arrive at your destination, you can use the Seat-Pack as an ideal replacement backpack, no matter whether you’re out with a cross bike, mountain bike, road bike or electric mountain bike.

The Ortlieb Seat Pack - L is obviously a high quality piece of kit. The strong materials used to provide the waterproofing and solid straps illustrate the durability of this pack and the thoughtful design make it really easy to mount onto the seat post. There are other practical features which make this pack a standout such as the easy access chord on top to stow jackets or gear and the compression valve which allows you to get the air out of the pack to make it more compact.

The narrow, tapered design reduces the chances of chafing on longer rides and provides more space between the rear tyre. This verdict involved both hardtail 29er and full suspension mountain bikes and the additional stiffness in the design ensured clearance between pack and tyre across a range of challenging terrains which other brands can fail to deliver. 

The Seat Pack comes in two sizes with this one being large. It can be rolled up to accommodate anything from 8-16.5L meaning that it is capable of fitting in a significant amount of kit. The size will put some riders off as it can extend out to over 70cm from the seat post which when full has an effect on the bikes handling. This might all be seen as overkill if you don't need that much space on shorter trips. However, this is an excellent piece of kit that provides plenty of space and does not limit your adventuring.

6 days bikepacking and bag is broke

Not impressed with the Ortlieb seat pack, only 6 days into my bikepacking adventure and the product has failed. One of the straps which goes around the seat post has broke, the Velcro has come away only leaving one strap to hold bag onto bike. I feel for the money I have paid for this product it should last far longer then 6 days!
