Bikepacking Saddle Bag or Under-Seat Bag?

For multi-day rides, a bikepacking saddle bag carries clothing and a sleeping kit behind the seat. Our waterproof bikepacking saddle bag with roll-top closure holds 10 to 14 litres in 420D TPU with 600D reinforcement and attaches at both the seat rails and the seat post to limit sway. For everyday riding, a small under-seat bag carries a spare tube, tools and keys: our bicycle saddle bag, waterproof bicycle seat bag and dry bike bag under seat are all made from TPU.

How Do You Stop a Saddle Bag Swaying?

Two-point mounting, a firm roll-top and heavy items packed close to the seat post keep a saddle bag stable. Compress the roll-top fully before tightening the straps. For frame and top tube bags, see our Bike Frame Bag collection, and for the full range, our Waterproof Bike Bag collection.

Will a bikepacking saddle bag fit my bike?

It needs enough clearance between the saddle and the rear wheel. Check clearance with the bag loaded, especially on full-suspension bikes.

Are bike saddle bags waterproof?

Roll-top saddle bags with welded seams keep out heavy rain and wheel spray. Small zippered seat bags are rain- and spray-resistant.
