BikePacking Seat-Pack

The BikePacking range is ORTLIEB’s new adventure touring collection of waterproof bags for the more adventurous tourers to favour the backcountry and off-road adventures which may require bikes without pannier racks.

Spacious and waterproof, the new  BikePacking Seat-Pack fastens securely to the seat post of almost any bike going including those with carbon seat posts, the mounting just requires around 6 cm (or 2.3 in) of clear space on the seatpost.

Designed to keep gear dry regardless of the weather conditions, the larger version features an adjustable volume between 8 and 16.5 litres thanks to the roll closure and a compression valve to let out excess air when packing content.

A shock cord can be used to strap down additional gear on the outside of the pack. Robust fabrics, custom stiffeners and an optimised strap design ensure the Seat-Pack performs in harsh conditions. The larger Seat-Pack can also act as a handy mudguard by blocking the spray from your rear wheel.

As with all large volume bags attached to bikes, stability is a key requirement which is why the Seat-Pack uses highly reinforced fabrics and fittings to ensure secure, movement free fitting to the bike as well as long-term durability.

Latest Updates

The BikePacking Seat-Pack has seen not just a cosmetic update with the new Matte Black colourway which replaces the previous Slate but there are also some small refinements over the previous version.

Firstly, the smaller of the two Seat-Packs (the 11-litre version) now features the same bungee cord webbing as the larger version, the cam locks on both sizes have been improved to further improve their durability and finally, a small toggle has been added to the purge valve which should make them easier to handle and operate.

ORTLIEB has also slightly further reinforced the front of the bag to help minimise sway - the principle being that if the bag is firmer at the point it meets the saddle then there isn't much scope for the bag to compress and expand creating a swinging motion whilst on the go.
