For the Long Haul or Short Day Trips, the 3-in-1 Gravel System Goes
The Gravel Travel System is 3 bags that work as one, giving you the freedom to create the ideal carry solution for adventures big and small. It consists of a bombproof 42-liter carry-on friendly backpack, a sling/hip belt, and an 11-liter day bag. All 3 pieces work together to create a compact kit, and uncouple easily to deploy on their own. A funded Kickstarter.
