The EXFIL-11 is made out of super-durable and water-resistant, UV-treated 1680D Polyester and attaches easily to any steel gas tank with incredibly strong built-in magnets. The interior is lined with high-vis orange nylon and has a convenient mesh pouch at the rear, and under the lid. Multiple audio grommets allow for headphones or charging cords. The clear map pouch on top is touch-sensitive so your electronic devices can be used without opening it. Both sides feature quick-access zippers for easy access to important items. Baffles on each side can be utilized to help the bag wrap over the contour of a gas tank strap, or left close for flat surfaces.
