The Ortlieb gear is bombproof, waterproof, and a good seat bag is a main part of a bikepacking setup. This seat pack is smaller than the Ortlieb Large pack (obviously) and is the perfect size for the Ramble, shorter duration adventures or for those that pack light. It’s also a good choice is you ride a smaller frame. The most important thing to consider when choosing the proper size is what are your long term plans for bikepacking. 1-2 overnights where you won’t need a lot of gear and using other packs…this is a great choice. I you’re looking to do longer expeditions or through areas where you might need more gear (extra jackets, larger sleeping bag, etc.), then the larger bag makes sense. Just roll it down to suit your needs.
The ORTLIEB Seat-Pack M is compact and spacious at the same time. Offering a payload of 11 liters, the waterproof seat bag offers a lot of stowage space for sizeable items that are not so heavy such as clothing and personal care items. The inside and bottom of the bag are stiffened, which ensures stability even in bumpy terrain. Thanks to the roll closure, adjustable straps and an additional compression valve, you can reduce your loaded Seat-Pack to an extremely compact size.
Outfitted with highly adhesive Velcro straps, the waterproof Seat-Pack M easily attaches to your bicycle saddle rails and seatpost. And given that you only need 6 cm of available space on your seatpost, the Seat-Pack is also ideal for smaller frames, full-suspension MTBs and bikes with dropper seatposts. The attachment to the saddle rails reliably holds the Seat-Pack M in the right position, essentially turning it into an effective fender.
