Frost + Sekers make very nice saddle bags in England. This is their version 1 Otis Saddle Bag with 16 liter capacity. It includes the quick-release mechanism which slides between your saddle and your seatpost (extra-long bolts for single and two-bolt seatposts included). It’s a sturdy system. The bag attaches to the QR bracket via two short Voile straps (stronger and more durable than the original leather). I include the original leather strap for the bottom seatpost mount but also a short Voile strap for that too (in matching black). Very little use on this, but of course the other day the trails were set and there’s a tad of dirt on the exterior (see photos). It’s made from a very tough canvas, with a waxed-canvas liner on the lid and the bib around the main compartment.
