For going on a multi-day excursion on a bike not fitted with racks, Ortlieb's Seat Pack provides a secure and lightweight way to carry clothing, tools, and other equipment. The roll-top pack is completely waterproof, made from polyurethane-coated nylon with reinforced fabric at saddle contact points. Inside, the pack is structurally supported by a plastic stiffener and two aluminum brackets that also attach the pack's two hook-and-loop seatpost straps. Up top, attachment is completed by cinching down the camlock side-release straps to the saddle rails for a four-point mounting system that won't loosen up over rough terrain.

Other features include a switchable air valve on the side to purge air for compressing loads, reflective accents, and a rear daisy chain that can be used to attach a clip-on tail light. IP64 Standard dust and water resistant. PVC Free.

Love, love, love, love this seat pack!

Waterproof! Built very solidly and with outstanding materials that should last for many years to come. Very spacious, yet fits on to a seat post with a mirror 5.5 inches of clearance. Use it for a bikepacking, or simply keep it on your bike for rides where you may need to store your jacket, tools, spare inner-tubes, snackfoods, extra energy,/electrolyte drinks, or anything else for that matter. I am using this for bike packing, touring, as well as commuting.

Great bag, spacious and works great in the rain too

It took me some time to install it properly as I have an older TREK carbon frame with a horizontal bar and therefore less room under the saddle to secure a bag. But it did work in the end.

The bad is light weight and contains a lot. I can put overnight clothing in there

It is also completely waterproof which was very useful on several occasions.

Also this store gave me a nice price on it as I saw it costs significantly more on amazon.

Well worth it!

Another great Ortlieb product!!!!

Great waterproof large seat bag. Attaches easy to bike. Like the valve to let air out of the bag. Like the bungi cords on the top of the bag. Well designed bag. I have taken bag on two day rides and bag has performed to expectations. Thanks Ortlieb!!!'

Great but a bit wobbly

First and foremost, it holds a ton of gear. Unfortunately if it is not loaded enough it will become wobbly as you ride. Other than that it does exactly what is supposed to do. It is also very waterproof

The Best BikepackingTouring Seatpack

I have the Pika and the Outpost to compare this to, and the Ortlieb beats them both. Those are $120 and $99 respectively, however I really do think you get your money's worth if you spend a little extra and get this one. All straps, buckles, and the bag body are very high quality. The air valve is extremely well designed, I hope ortlieb starts to include these on all their waterproof touring bags. I've used it on one short two week tour right before the cold season hit and it worked beautifully. At first I used it solely for my clothing, but unless the clothes are packed down very tight the bag sometimes gets floppy. I'm a lazy packer, so I started to put my tentpoles in along with the clothes and that helped the bag keep its shape better. Ortlieb seat pack and two back rollers on front pannier racks should give you plenty of space for touring through countries like the US, Canada, Japan, etc.

awesome but expensive

this is a great piece of kit, but more expensive than similar items. I had to buy this one though as it is the one requiring the least distance saddle to tyre clearance. Really worth taking your bike to the shop to try them for size before deciding. Also great that it is waterproof as many others are not. The staff were really helpful with accommodating this.
