A micro sized seat pack for packing ultralight on multi-day adventures or storing some extra clothes on a long day ride.
The Pack Sack has a max volume of 5L, which when paired with a handlebar bag can be just enough room for a lightweight overnighter. The 25mm low profile seat post strap means it is possible to use with a dropper post, you would of course need to check for tyre clearance and possibly use a clamp such as the Wolftooth Valias to reduce travel.
A piece of webbing passes over each saddle rail and down into a ladder lock buckle on either side of the bag, enabling you to cinch the bag up tight to the seat. The opening at the end of the bag is a simple roll-top design - roll then end down and place the strap over the end and into the buckle near the back of the seat. Tighten it up and you are ready to go.
