Instead of a bulky tool roll, we opted for a slim shape and rear-facing zipper which make it possible to access your small items in a hurry (plugs!) while leaving the bag on the saddle.
The YKK waterproof zipper and water resistant lining mean that your tool and plugs won't get drenched.
Fit - Does your seat have rails? Then it'll fit via the included velcro strap. For added security synch the zipper pull under the velcro. Bonus - Reflective details at the rear.
