Saddle Roll

Lightly used with marks, etc.
Fully functional

Here is manufactures description
"The next step in the evolution of the saddle bag. Designed to hold two road tubes, tire levers, a multi tool, CO2, as well as miscellaneous small parts. A waterproof zippered Dyneema pocket offers a lightweight, abrasion resistant, yet still see-through solution for carrying patch kits, valve adaptors, and chain links.

Tools and other small items fit between both tubes when the roll is folded for a completely rattle-free ride. A leather patch protects against abrasion with seatpost hardware, while a Voile ski strap provides a sleek, strong single-strap attachment system that won’t wear out or chafe your shorts like traditional hook-and-loop fasteners."
